Two New Hydro Vacuum Excavation Projects

The hydro vacuum excavation services that our company offers come in handy in many different contexts, for many different types of clients. That’s because these services are totally safe for buried utilities, even sensitive lines like fiber optic cables. Over the years, Thompson Industrial Services has conducted many hydro vacuum excavation projects and has never yet damaged a utility line—despite the fact that we uncover those lines during nearly every project! This month, we wanted to highlight two recent projects that illustrate two very different applications for this flexible excavation approach.
Locating a water pipe leak using hydro vacuum excavation

Making Way for a Pipeline
Digging two holes in preparation for laying a new pipeline may not sound like a project that would require a specialized excavation approach. But it definitely is when the pipeline is being laid at a power plant! For the sake of safety, the preparation could not make use of traditional digging equipment, and that meant calling in the Thompson Industrial Services safe excavation team. Our job was to dig two holes, each measuring four feet deep and twelve feet in diameter, one hole at each end of the new pipeline at the point where it would tie into existing pipe. Clearly, it was very important to dig the holes without causing any damage to the pipe that was already in place. Our digging method, which uses pressurized water to loosen soil and then vacuums it away from the excavation site, quickly  and safely did the job. There was an additional factor that threatened to complicate the project, though: once our team dug the holes, water began to fill them again. Fortunately, our hydro vacuum excavation equipment is also equipped to remove water from the excavation site, so we kept the holes clear and dry while workers installed the new pipeline. The client was very pleased with the results and has indicated an interest in working with Thompson in the future!
Finding a Water Leak
The second of our hydro vacuum excavation projects involved, not a new pipeline installation, but locating a leak in an existing water pipeline. At another power plant, a water leak was negatively affecting production and it was essential to locate it quickly. Again, mechanical digging equipment was not an option, since it could easily damage pipelines even further. There were also buried power lines at risk, which would be disastrous to strike with a backhoe or even a hand shovel. Our hydro vacuum excavation team got to work, digging near the pipeline to pin down exactly where the leak was located. At one point along the pipeline, it was necessary to dig through a sidewalk—no problem for the highly pressurized water that we use in our excavation process. As of this blogpost’s writing, the project is still underway, although our team believes it has identified the source of the leak. Feedback from the client during the project has been very positive; as with most of our jobs, the employees at the facility have been surprised at the safety and speed with which our team has worked.
Safe Digging for Different Projects
These two jobs illustrate the value of hydro vacuum excavation for projects at power plants, where mechanical equipment may not be used to dig on the property. But any time there are known utilities buried in the area, or there is the possibility that they may exist, our services can accomplish the necessary excavation without jeopardizing the lines. Another important application of this service is excavating in contamination-sensitive environments. As soil is loosened and removed from the site, our vacuum equipment contains and removes it, storing it for later disposal or for replacement once the work at the excavation site is complete.
The companion application to our hydro vacuum excavation service is pneumatic vacuum excavation. This process comes into play when an environment is so sensitive that even the moisture created by pressurized water blasting is a problem. Pneumatic digging uses pressurized air instead of water and is also extremely gentle on utilities and communication lines.

Taking Boiler Tube Cleaning into the Future

At Thompson Industrial Services, our innovation in automated cleaning solutions has transformed many of our processes, whether they involve hydroblasting, chemical cleaning, or spraying a specialized product like FINFOAM. In each application, replacing a hands-on approach with remotely controlled robotic tooling has helped us make important progress in safety, speed, accuracy, and power. Boiler tube cleaning provides what may be the clearest example of just how much progress is possible when we make the best use of automated technology. If this is a maintenance topic that has always been a “thorn in the side” of your facility, keep reading—Thompson Industrial Services can help!

Automated boiler tube cleaning transforms this core maintenance task.

Automated Boiler Tube Cleaning Equipment
The equipment we use for automated boiler tube cleaning is compact—it’s small enough to be inserted through the mud drum manway, gaining access to boiler tubes very quickly as it is manipulated remotely by one of our expert, highly trained technicians. Once the unit is in place, a camera system allows the technician to clearly see what the cleaning needs are, track progress, and document the results once the cleaning job is complete.
The automated tooling is expertly designed to clean boiler tubes completely, safely, and quickly, delivering up to 50 pounds of push force to clear plugging. One important factor in the speed of this cleaning approach is the fact that the tooling cleans in both directions as it is manipulated—essentially performing twice as much work as a human technician would be able to perform through a hands-on cleaning approach.
Customized for Your Equipment
Each boiler tube cleaning job is unique, and we customize our flexible automated equipment in order to bring the highest possible level of service to each of those jobs. This is an incredible efficiency benefit for each of our clients; the more closely the solution is customized for a piece of equipment, the more thoroughly the unit will be cleaned and the more effective it will be when it is back online.
Our teams use a detailed, careful project planning approach before beginning any job. No matter how “routine” a cleaning job may seem, a creative solution may be able to remove tough, years-old deposits that previous cleanings were not able to touch. It may also cut downtime by hours or even days, thanks to increased cleaning power and the ability to keep human workers out of harm’s way throughout the job. This commitment to look at each project through the lens of innovation and to never be content with the way things have always been done is part of the integrity that our clients value in our industrial cleaning teams.
Boiler Tube Cleaning Expertise
This state-of-the-art automated boiler tube cleaning equipment is powered by decades of experience. Our technicians understand the capabilities of the tools they use to clean boiler tubes and other industrial equipment, and they carefully determine the safest, most effective solutions for each cleaning project. If a client’s proposed boiler tube cleaning method—or the one that other service providers have used in the past—does not appear to be the optimal one, our team will propose an alternative that may preserve the client’s equipment and lead to better results for the long term.
Waste containment during any boiler tube cleaning job is an aspect that our technicians take very seriously as well. The debris and chemicals removed from equipment are often hazardous to the environment and to human workers, and we use advanced equipment and methods to safely dispose of them. In some cases, the client’s facility policies even require that we collect all debris, fluids, and chemicals produced during a cleaning job and transport them off site without allowing any to escape. Our experience and advanced equipment, including vacuum technology and high-capacity units, allow us to meet these expectations while still minimizing downtime for the client’s process lines.
Automated boiler tube cleaning may be an incredibly valuable service for your facility, and our teams are uniquely qualified to perform it safely and quickly. We encourage you to contact us and tell us about your cleaning needs, as well as safe excavation, combustible dust removal, wet and dry waste vacuuming, and other complex industrial cleaning services.

Automated Hydroblasting Benefits a Paper Mill

If you ask any of our clients what they like most about working with Thompson Industrial Services, there will undoubtedly be a few common answers. Our commitment to safety is one of the most mentioned factors during follow-up conversations. Another big one is our integrity and the many accountability measures we implement during each job, including reports detailing improvements in efficiency following a job. A third popular benefit is the fact that our continually developing automation methods cut down on the amount of downtime needed for routine maintenance tasks. At a paper mill in Georgia, this minimized downtime was on display during a recent evaporator cleaning job. Since we had performed the same process in the past using hands-on techniques, it was easy for us to compare those results with those of our automated approach, and there was quite a difference, as you will see.
Automated hydroblasting improves both safety and performance at once.

Evaporator Tube Hydroblasting
At the paper mill in question, two evaporators had lost efficiency due to plugging. Our task, as before, was to unplug the evaporator tubes during scheduled downtime and get the equipment running normally again. Each evaporator has about 2,000 tubes, and 60 and 20 percent of the tubes, respectively, were plugged. The time-consuming, tedious nature of clearing the tubes is already obvious, but the situation is made worse by the fact that the tubes are only accessible through confined spaces. During hydroblasting by hand, these confined spaces create a serious safety hazard for the technician and slow down the cleaning process quite a bit.
In the past, the job required seven to eight twelve-hour shifts, with ten technicians on each shift and two water pumps operating the entire time. While manufacturing plants have largely grown accustomed to these lengthy outages for routine maintenance, in many cases our technology is changing the game and getting equipment back online much more quickly.
Automated Hydroblasting Cuts Downtime Drastically
Instead of hydroblasting by hand, this time our team implemented a complex system of powerful hydroblasting equipment, manipulated by a triple flex lance machine. Our operators controlled the equipment from a distance, keeping them out of the hazardous confined spaces and actually giving them greater control over the tooling.
Because the automated hydroblasting does most of the work, we only needed four men per shift instead of ten. In addition, we only ran one pump instead of two. And because the automated equipment cleans with full pressure on both the upward and downward stroke, our team actually performed twice as much cleaning in total as they would with a hands-on approach. The savings associated with this manpower and equipment reduction alone for the paper mill totaled $60,000.
Even better, the cleaning work was completely finished in less than five twelve-hour shifts instead of eight. By the time our team left the site, the evaporator tubes were 100% clear and ready to resume normal operations. Many factors resulted in the shorter timeframe; for instance, with no confined space entry by our personnel, we avoided the associated safety precautions. Additionally, the automated positioners are so precise and powerful that the actual hydroblasting work takes place much more quickly than when the equipment is in the hands of human technicians.
Important Benefits for Paper Mills
These dramatic cost-saving results have attracted the attention of those in the pulp and paper mill industry, particularly in the southeastern U.S. These facilities often rely on units with confined spaces, long-neglected cleaning needs, and debris buildup that is very difficult to remove. Automated hydroblasting solutions like the one we used at the Georgia paper mill often present ideal answers to questions that paper mill managers have been asking for decades.
This story is just one example of the many solutions that our researchers are constantly developing in order to better serve our industrial and commercial clients. Every time we are able to accelerate a boiler, evaporator, or heat exchanger cleaning project using automated tooling, we save thousands of dollars for our clients without sacrificing anything in the way of quality. In fact, the more powerful equipment and higher level of precision gets equipment more thoroughly clean than ever before.

Dry Ice Cleaning: Incredibly Green and Incredibly Powerful

We bring in our dry ice cleaning services to solve many of our clients’ most challenging, delicate, and unusual industrial cleaning needs. Explaining just how this cleaning process works doesn’t take very long, but we could go on forever describing its fascinating scientific properties. The more you learn about how we clean sensitive surfaces and equipment with frozen carbon dioxide, the more you understand why this is such an important, valuable asset to our customers. Today, we’ll tell you about a few surprising dry ice cleaning facts, then finish up with a real-life example of what is possible with this incredibly green, incredibly powerful method.
A dry ice cleaning project in progress
No Carbon Footprint
You will probably recognize “carbon dioxide” as one of those greenhouse gases that the government is always looking for new ways to limit. One of the questions you might have when you hear that Thompson Industrial Services blasts frozen carbon dioxide as a cleaning medium is, “Doesn’t that produce large amounts of polluting greenhouse gases?” In fact, the source of the frozen CO2 that we use is the secret to keeping the process totally green. Some of our other cleaning services produce CO2 as a by-product, and we capture that gas for later use in dry ice cleaning. We freeze the CO2 as pellets, then use them to remove all types of contamination and coatings from delicate equipment and surfaces. Thus the only CO2 released into the atmosphere during a cleaning job is the gas that was captured during another process earlier on.
From Dusting to Blasting
Dry ice cleaning can be incredibly powerful, in the “normal” sense of that word. Stripping paint from a surface in an environment where moisture, heat, and conductivity are unacceptable is quick and easy with a high-pressure cryogenic cleaning application. But we are also able to adjust our approach and use the same basic process to clean surfaces as delicate as paper and books. The science behind the process—tiny, controlled explosions at the surface to be cleaned as the frozen CO2 suddenly evaporates into the atmosphere—allows for a huge range of different specific applications that blast away debris while leaving the underlying surface unharmed.
Food Grade CO2
Cleaning foodservice or, more importantly, pharmaceutical manufacturing equipment can require a huge amount of preparation, downtime, cleaning, and testing if the cleaning process involves chemicals or other substances (as in sandblasting) that absolutely cannot be allowed to come in contact with the production line. Dry ice cleaning, on the other hand, utilizes frozen carbon dioxide that is actually approved by the FDA, EPA, and USDA as food grade and totally safe for use in these highly controlled industries. This means that in many cases, we can perform maintenance on equipment used in food/beverage and pharmaceutical manufacturing with minimal or even no downtime at all.
A Brief Case Study
Electronic equipment is one of the major categories that we use dry ice cleaning for. Hydroblasting can damage electronics through the introduction of water, and the tiny particles used in sandblasting can also cause damage. Recently, we conducted a cleaning at an automobile manufacturing facility in order to remove production debris from some robotic equipment. The debris buildup was having a negative effect on the final product, and in order to restore quality, it had to be removed. Our team determined that, because of the electronics involved, the safest and quickest way to remove the debris was to use our dry ice cleaning process. Within the client’s designated timeframe for the cleaning job, we successfully blasted the robotic equipment with frozen CO2, cleaned it thoroughly, and restored the process line to its original efficiency and quality. The client was particularly impressed with our team’s planning phase, noting that our technicians took the time necessary to understand the problem, take into account all the relevant factors, and settle on the best possible solution before starting work.
Dry ice cleaning may be the process that your facility needs in order to remove particularly troublesome contamination in a sensitive area.

Cleaning Heat Exchanger Tubes in Short Order

A great deal of the work that we do for our clients is in the form of scheduled maintenance. We have many clients that have us come to their facility on an annual or other regular basis, and it’s not uncommon for a new client to schedule us to accomplish a long-overdue, exceptionally difficult cleaning job. But another important segment of our work at Thompson Industrial Services is responding to emergency cleaning needs. Cleaning heat exchanger tubes that have suddenly fouled out, vacuuming spills of hazardous substances, and clearing blocked lines are a few examples of our emergency cleaning services, which we approach with the same sense of urgency that the client is experiencing when a situation jeopardizes the production or safety of their facility.
A before/after comparison of the heat exchanger tube bundle

Responding to the Call
Our emergency cleaning hotline (1-800-849-8040) is open 24 hours a day, 365 days a year and staffed with full-time Thompson personnel. That’s because no one can predict when a spill, blockage, or contamination event is going to bring production to a halt or endanger employees and property. That’s what happened exceptionally early in the morning as a major oil refinery in Tennessee experienced fouling in one of its crucial heat exchanger tube bundles. The production schedule required the tubes to be cleaned as soon as possible, so the unit manager made a wise choice: he called Thompson Industrial Services and asked for our immediate help.
Cleaning heat exchanger components is one of our core services, so we were ready to respond to the refinery’s call. We sent out a highly skilled four-man team, and they arrived at the site early to scope out the job and set up the necessary equipment. That initial work was finished by 9:00 AM, and the team was ready to work well before the bundle was opened up at 11:00.
Minimal Downtime
Cleaning the heat exchanger tube bundle was a particular challenge since the deposit had been “cooked” due to severe overheating. There were 480 tubes in total, and our team needed to clear the plugged fouling as quickly as possible in order to minimize downtime. The clock was ticking once our team began work at 11:00—every hour represented downtime and lost production, so we worked as quickly as possible while upholding our zero incident safety policies. Just after 3:00 PM, we completed the cleaning and an IRIS inspection was conducted to verify that the tubes were cleared of the fouling and ready to return to operation. As expected, the cleaning was a success and the oil refinery returned to full production.
Relieved Management
As always, we contacted the facility’s manager overseeing the team cleaning the heat exchanger bundle later in the afternoon to get his review of our team’s performance. The minimized downtime had made quite an impression, and the manager specifically thanked our team for their speed in getting to the site and getting set up for the cleaning process. He also noted that the team’s leader stayed present at the bundle from the beginning of the job to the end, closely monitoring everything that the team did and ensuring that the cleaning observed all safety precautions for the unit.

Business as Usual
Accomplishing an urgent, pressing job like cleaning heat exchanger tubes on short notice is business as usual at Thompson Industrial Services. By keeping advanced cleaning equipment on hand at all times, such as automated lancing equipment, we maintain a state of readiness to respond to emergency needs like that of the oil refinery in Tennessee as well as pulp and paper mills, power plants, manufacturing facilities, and other industrial sites. Our commitment to automated technology research is changing the game when it comes to emergency cleaning processes that used to require many hours or even days of downtime. Once we set up our remotely controlled positioners and hydroblasters, the incredible precision and power of the equipment dramatically accelerates the pace of cleaning compared with traditional methods.
Many clients that contact us for an emergency cleaning end up engaging our services for cleaning heat exchanger and other industrial equipment on an ongoing basis as well. It’s always a pleasure for us to see the relief on the faces of facility managers when we resolve a potentially disastrous problem for them in record time, minimize lost production, and earn their trust for regularly scheduled cleaning in the future.

Three Things Hydrolazing Can Do

Like many of our industrial cleaning processes, hydrolazing is very versatile. We think you’d be quite surprised at the range of different projects that we have accomplished using this technique, often after the clients have been repeatedly disappointed by failed attempts to do the same job using other methods. Unfortunately, we can’t tell you the whole story for each of these projects, but we would like to give you an introduction to hydrolazing by explaining three things that it does very well. If any of these problems sound familiar to you, it might be time to contact our experts and arrange a meeting!
Our automated hydrolazing equipment hard at work
1. Surface Preparation
A homeowner might feel like he has a big job ahead of him if he has to scrape “popcorn” texturing off the ceiling before painting it. But we are talking about jobs far beyond that—surfaces in commercial and industrial facilities that have been coated with heavy-duty materials such as non-slip coatings. These coatings are made to last, and removing them from a surface can be a prohibitively long, expensive process using traditional methods. Another common situation is the presence of multiple paint layers, all of which must be stripped away before the new surface coating can be applied.
Our hydrolazing experts have handled these surface preparation challenges with flying colors. One project even required our team to remove over 20 layers of paint from a very large surface area—to the client’s surprise, we wrapped up the job well within the estimated time frame.
2. Process Line Cleaning
Depending on the type of process line, debris buildup can be hard enough to withstand normal cleaning applications. The manager can easily come to the conclusion that the facility’s only option is to perform frequent “partial” cleanings, removing part of the buildup but leaving the toughest deposits intact. Even decades-old layers of debris, however, are no match for an experienced hydrolazing team. The ultra-high water pressure (“UHP”) generated by our equipment cuts through essentially all types of buildup without causing damage to the surface underneath.
Our hydrolazing approach is ideal for pre-commissioning system cleaning (e.g. steam piping, hydraulic and lube oil equipment), boiler tubes (internal and external), heat exchangers, pipe, reactor chambers and pressure vessel cleaning, restoring equipment to its full efficiency—this is no partial cleaning!
3. Automated Solutions
Part of the secret of our hydrolazing success is the arsenal of automated, robotic positioners and associated equipment that we use in tandem with our ultra-high pressure water blasting tools. The simple truth is that there are limitations to the accuracy and thoroughness that a human technician can achieve when handling an extremely hazardous hydrolazing tool in person. In addition, tight spots are difficult or impossible for a human technician to reach and clean completely. By planning the entire cleaning process ahead of time, setting up cleaning tracks, and mounting hydrolazing equipment on specially designed positioners, our teams aim not just for a successful job, but one that is completed on time, within budget limitations, and to a degree that exceeds the expectations of the client.
About Hydrolazing
Hydrolazing is also referred to as ultra-high pressure (UHP) hydroblasting or water blasting. Obviously, it is similar in its basic concept to our standard hydroblasting services, but the extremely high water pressure (40,000 PSI) expands its capability to demolish layers of even the toughest deposits and surface coatings. Another major difference is the low total water volume that hydrolazing uses. A typical cleaning only uses two to four gallons of water per minute, and by utilizing our vacuum recovery equipment, our teams have the capability to avoid environmental contamination completely during a job.
Because hydrolazing removes layers of deposits so thoroughly, clients often find that they can cut back on scheduled equipment cleanings compared to past requirements. With fewer overall cleanings, reduced downtime for cleanings, and dramatically higher efficiency for equipment that is cleaned completely, hydrolazing offers huge financial savings for facilities that take advantage of its power.
To learn more about hydrolazing, our industry-leading automated solutions, or our additional hydroblasting services, get in touch with us today. If a surface preparation, process line debris buildup, or other difficult cleaning need has defied all attempts so far, our hydrolazing experts can tell you whether this revolutionary approach is the answer you have been looking for.

Vacuum-Excavation Services: “Potholing” and Other Tasks

The word continues to spread about the multitude of benefits from Thompson’s vacuum-excavation services. Industry magazines have published stories about them, and clients that have had our teams perform excavation projects for them regularly refer us to others. What is so different about what we do? Our approaches to safe digging—often times referred to as “daylighting”—which utilize either semi-high pressure water or compressed air strategically in harmony with our vacuuming service safely in lieu of intrusive heavy equipment (AKA “yellow iron”), which allows us to do what used to be extremely impractical or dangerous: dig in areas that may have buried utilities without causing any damage to even delicate wires and cables. Using a recent successful project as an example, we’d like to introduce you to the huge benefits that our pneumatic and hydro vacuum excavation services provide for our clients.

One of our vacuum excavation trucks

Anticipating Buried Utilities
Many times, a client of ours needs to excavate a site in order to begin construction, but can’t risk damaging water pipes, gas lines, buried power cables, communication wires, fiber optic cables, or the many other utilities that run below the surface of the ground. Prints of these sites may be long outdated or simply incomplete, if they exist at all. This was just the case at a port on the coast of North Carolina, where a client needed some “potholing” done to prepare for the construction of a new structure. Our team got to work digging the holes, and after just a few days of work, we discovered the same fact that we discover on almost every vacuum-excavation job: there were, indeed, buried lines that no one knew about. Thanks to our process’ gentle and non-aggressive technique, the lines were readily exposed but not harmed whatsoever, and the client was able to avoid the expense and project interruption that would have occurred if traditional digging equipment had been doing the work.
Keeping it Contained
While our work at the North Carolina port was in a relatively open area, our pneumatic vacuum excavation services often operate in much tighter circumstances or even remote distances from our vacuum truck. Within the context of a nuclear power plant, for instance, clouds of dust from mechanical excavation dumping or generating mud from hydro-excavation may not be ideal or even acceptable. The “vacuum” element of our excavation services helps our team keeps the radius of the excavation very small, minimizing the effect of the work on the surrounding area. With pneumatic-excavation, our compressed air tools dislodge the soil loose and to the proper, size, complemented by vacuuming the debris immediately and either dispose of it or store it for use as (dry) backfill when needed for same.
Hydro-Vacuum Excavation Services
Hydro vacuum excavation is the complementing partner technique to our pneumatic approach. In some cases, using pressurized, low volume water instead of air is more effective—for cutting through rocky soil, for instance—while still safely exposing buried utilities. Generally, hydro-vacuum excavation incremental rate is faster than the pneumatic version, but in many specialized situations, the introduction of water complicates the project or task at hand. It can make it difficult, for example, to shore up the sides of an excavation site, and if electrical lines are involved, the conductivity of water is a serious concern. Another significant benefit of utilizing a dry (i.e. with air) process is the ability to “step down” the terrain slope and thus minimize shoring, plus readily permitting work in a dry trench without the mud to contend with, not to mention the ability to backfill with the extracted matrix immediately without having to wait for it to dewater and dry out. In these situations, the slightly slower pace of pneumatic-excavation is a great trade-off for the benefit of the increased safety, feasibility, and stability during the digging project.
Repeat Clients
There is one unmistakable sign that our pneumatic-vacuum excavation services are getting the job done right, and that is when a client calls us again to do additional work. After we completed the potholing job at the North Carolina port, the client asked us to take our vacuum-excavation services to some of their other job sites to perform similar work. Once a company sees firsthand the safety, efficiency, and financial benefits of this unique digging approach, it is very common for managers and field supervisors to develop an ongoing working relationship with Thompson Industrial Services for other excavation needs.
Pneumatic excavation truly shines when we put it to work in settings that seem to make digging all but impossible. If you have been puzzling over an upcoming excavation project at a nuclear plant, another highly sensitive area, or a site that has no reliable information concerning buried utilities, we hope that you will email us or give us a call. Our vacuum-excavation services may be the perfect solution for your difficult problem. We look forward to telling you more about them as well as our many industrial equipment maintenance and emergency cleaning services.
