International Case study: matla power stationNu Flow’s innovative pipe rehabilitation solutions are implemented by some of the most powerful companies in the world, including some of the world’s largest energy companies. Nu Flow is the only inside infrastructure company that manufactures and installs its solutions, providing our customers a monumental amount of quality control, quicker project completion time and the ability to create a tailored solution.

Project: Use the Nu Line process to rehabilitate chiller pipes in-place.

Customer: Eskom, established in 1923, is the largest producer of electricity in Africa. It is the primary public electricity utility company in South Africa (95% of all electricity for the country), provides Africa with about 45% of its electricity and controls the only nuclear power plant on the continent. Eskom is also listed in the world’s top 7 electricity companies for their generating capacity.

Site: The coal-fired power station in Mpumalanga, South Africa, called the Matla Power Station. It was commissioned in 1983.

System: Chiller pipes with a diameter of 110mm (4 inches) that run through 6-story structural columns and floor slabs throughout the entire building.

Problem: The chiller pipes experienced heavy corrosion and scale build-up that reduced their efficiency. There was also the threat of leaks, which could damage the building. The customer wanted to find a long-term solution that would not cause destruction or business downtime.

Circumvention: If the customer had chosen a traditional repipe, where the structural columns and flooring would be destroyed in order to replace the pipes, the work would have taken four months. Scaffolding would have been erected around the entire building block, the building would been defaced, floors removed, structural columns torn down, the pipes pulled out, then replaced and new concrete would be poured over the pipes. The extremely strict health and safety regulations at the power station further ruled out the option of replacing the pipes.

Solution: Nu Flow’s patented Nu Line process was used to rehabilitate the pipes and the project only took three days. First, the chiller pipes were descaled using an abrasive agent pushed through the pipes with clean, compressed air. Once the pipes were back to their original diameter, the pipe system (throughout six stories) was rehabilitated with our epoxy coating process. Using a unique, blown-in technology, our red epoxy was pushed throughout the pipes to cover their interiors, creating a barrier coating that will prevent scale build-up, corrosion, pinhole leaks and other common failures.

This entire process was completed utilizing existing access points, so there was not any destruction to the building. Since there wasn’t any destruction and the job was completed in such a short amount of time, there was not any business disruption or lost revenue for the customer. Nu Flow’s unique pipe lining solutions keep predominant businesses and facilities running.

A traditional repipe for this power station would have taken four months. Nu Flow completed the work within three days.

Case study: California County Central heating power plant

Case study: mall on Las Vegas strip

Traditional repipes take the existing pipe systems out of commission, resulting in lost revenue for businesses that rely on those pipe systems for normal operations. Nu Flow is dedicated to creating unique solutions to ensure minimum disruption to our customers. In this project, our team created a bypass piping system so that the prestigious mall’s food court would be fully operational while we rehabilitated a failing grease line.

Project: Use Nu Drain to rehabilitate grease pipes in-place.

Customer and Site: The food court within the landmark mall located on the Las Vegas Strip, in Las Vegas, Nevada. This mall has high-profile tenants, such as the M&M’s World, the Coca-Cola Store, Outback Steakhouse and Hard Rock Café.

System: A horizontal grease line that services the restaurants’ kitchens in the food court. This cast iron pipe line has a 4" diameter and penetrates a concrete wall that is two feet wide.

Problem: During a renovation for this mall, the customer wanted to repair the failing grease line. But part of the grease line goes through a two-feet-thick concrete wall.

Circumvention: If the customer had chosen a traditional repipe, the food court would have experienced business closures. The concrete wall would have been destroyed, resulting in weeks of additional work, higher costs and a massive mess from tearing down the wall and rebuilding it.

Solution: Nu Flow technicians utilized several existing access points to clean and retrofit this horizontal grease line. The job was completed in one day, as opposed to the weeks of work a traditional repipe would have taken.

First, using existing access points, a Nu Flow pneumatic cutting tool was used to break apart the build-up inside of the pipes and return them to their original diameter. Then, our Nu Drain system was installed using a patented Pull-in-Place process. Once the epoxy cures, a seamless structural liner was left inside the host pipe. This protective liner will prevent breaks in the pipe, corrosion build-up and other common failures; greatly extending the useful life of the pipe system. The Nu Drain process was installed without causing any destruction to the building, and a grease bypass system was installed so there were no interruptions to the restaurants while our technicians rehabilitated the pipes.

“The mall chose Nu Flow because they were seeking a solution that would avoid costly outages, disruption to revenue for their tenants, the destruction expense and

chaos that comes with traditional plumbing repairs.”

- Andrew Felsburg, Account ManagerNu Flow

Las Vegas Mall’s Food Court Remains Open During Pipe Lining

Nu Flow completed its first project for a California county and is looking forward to expanding its presence in the political subdivision market. With a long customer list of municipalities and government entities across the United States and Canada, the world’s leading small diameter pipe lining company provides many fiscal and operational benefits for counties and municipalities, alike. The below-mentioned project demonstrates that pipe system rehabilitation for a county facility can be achieved without causing any destruction to a property or causing any disruption to operations.

Project: Use the Nu Line system to rehabilitate an HVAC system without causing destruction.

Site: A California county’s central heating power plant provides heating and cooling for several county office buildings in the downtown area.

System: Steel HVAC pipes that run 300 feet from one heating and cooling tank to a return tank within the plant. The 4" diameter pipes are located four feet underground, surrounded by 480 volts of electrical conduit lines. The pipe system is more than 30 years old.

Problem: An evaluation of the pipes revealed that they have a lot of interior corrosion. The customer wanted to repair the aged pipes, but did not want to take the chance of cutting any electrical lines, due to the high voltage.

Circumvention: If the customer chose a traditional repipe instead of Nu Flow’s innovative technology, then normal operations within the plant would be disrupted. The concrete above the pipes would have to be jackhammered and removed. The pipes would also have to be carefully removed without touching the electrical conduit lines, which could be infeasible. A traditional repipe would be severely inconvenient, messy, destructive and dangerous for the central plant.

Solution: The customer was excited to see the benefits of pipe lining versus a traditional replacement in their facility. Nu Flow technicians used existing access points to clean and line the HVAC system, preventing the need for any destruction to the county property. Clean, compressed air pushed Nu Flow’s High-Temp epoxy through the pipes, creating a barrier coating after it cured. This epoxy coating will protect the pipes that carry water up to 200 degrees Fahrenheit, and in addition, prevent future corrosion build-up, pinhole leaks and other common failures. Nu Flow’s non-intrusive pipe lining process, Nu Line, preserved the electrical conduit lines and prevented any disruption to the facility’s normal operations, while greatly extending the useful life of the pipe system.

Nu Flow’s non-destructive pipe lining technology is a preferred choice when the building is going through a remodel. Our innovative, Pull-in-Place solution can be installed without causing any disruptions or obstructions to other contractors’ renovation work. The property management company that hired us for this project was so pleased with our fast and efficient work that it continues to utilize Nu Flow’s pipe lining solutions for its buildings.

Project: Use Nu Drain to rehabilitate failing storm drain pipes without disturbing the building’s renovation process.

Site: An eight-story building that was constructed in the 1980s. The building went through a remodel after the county’s police headquarters bought it.

System: More than 250 feet of 3" and 5" diameter cast iron storm drain pipes. The four vertical stacks run from the roof into the basement, and horizontal storm drain lines are located in the basement’s ceiling.

Problem: The storm drain pipes experienced cracks and severe corrosion, which are common failures for cast iron drain pipes. In addition, the building was undergoing a remodel for the new tenant, the county police headquarters, so the customer required a solution that would prevent destruction and disruption to business operations.

Circumvention: If the property management company had chosen a traditional repipe instead of Nu Flow’s non-destructive solution, the police station’s remodel would have taken much longer to complete. The work turning the basement into a criminal evidence warehouse would cease while the ceilings would be torn apart and the pipes replaced. The four vertical stacks that go through the building would also need to be replaced, causing an enormous amount of destruction to the building and a relocation of some offices.

Solution: A narrow timeframe for which the job needed to be completed was provided by the customer, and Nu Flow was able to complete the project within that window. The storm drain pipes were so badly corroded that half of the pipes’ interiors were blocked, so Nu Flow technicians used our pneumatic cutting tools to return the pipes back to their original diameter. Then the Nu Drain liner was installed using existing access points in the basement. This protective liner is a long-term solution against corrosion, build-up, leaks and other failures.

Nu Flow’s drain lining technology was installed without causing any disruptions to the other remodeling contractors. While renovating commercial buildings, property managers benefit when they utilize Nu Flow’s innovative solutions to extend the useful life of aged pipe systems, as well as prevent the unpalatable disadvantages of a traditional repipe, which include extended project duration, destruction, higher expenses and tenant displacement.

Nu Flow Is The Preferred Choice During Remodels



Whether you are planning to install brand new pipes in easily accessible areas or rehabilitate failing pipes in hard-to-access areas, Nu Flow has the nondestructive solutions that will save you money, time and hassle. In this particular project, Nu Flow highlights its unique ability of being able to line a wider variety of pipes than its competitors.

Project: Use dual technologies to rehabilitate an HVAC system in-place, as well as brand new HVAC pipes before installation.

Site: The multi-story office building for the Iowa Farm Bureau Corporate Headquarters, located in West Des Moines, Iowa.

System: Approximately 2,000 feet of HVAC pipes. These black iron pipes have 8", 10" and 12" diameters and include dozens of elbows. The pipes are hidden inside walls and other challenging places.

Problem: The HVAC system was past its useful life, so the building engineers looked for a company that could rehabilitate difficult-to-access pipes in-place.

Circumvention: If the customer had chosen a traditional repipe instead of Nu Flow’s nondestructive technology, the building would have encountered severe demolition and the building tenants would have experienced business disruptions, including temporary office relocation.

Solution: Building engineers looked for a company that could rehabilitate difficult-to-access pipes in-situ and chose Nu Flow because of our powerful resume of past high-profile jobs and our ability to work in remote areas. Nu Flow was able to provide the customer with an innovative and unique solution: a hybrid system of our pipe lining technologies. Technicians used our patented Nu Main system to install felt liners with our unique High-Temp and chemical-resistant epoxy inside the 8", 10" and 12" diameter stacks. These epoxy-soaked liners cured to create new pipes inside of the failing host pipes. Our Pull-in-Place technology utilizes existing access points, so there wasn’t any destruction to the building.

The exposed HVAC pipes that are easily accessible were replaced with brand new pipes that had already been pre-lined (using the same Nu Main process as explained above), in order to extend the life of the brand new pipes.

Only Nu Flow can provide its customers with out-of-the-box, tailored solutions to fit our customers’ needs. This customer benefited from a faster project completion time, lower cost, no business disruptions and an effective, long-term solution against failing HVAC pipes.

“We are saving this customer an extraordinary amount of time and money by structurally relining

the existing pipes and the new pipes. This customer is doing a lot of preventative measures

right now, and this is one of them. This will guarantee a long-lasting system.”

- Paul Eaves, Regional Manager,Nu Flow

Cleaner Magazine, March 2014

A contractor cleaned clogs from a 290-foot-long gravity grease line at Circus Circus Hotel and Casino in Las Vegas, Nev., for a year. As service calls increased in frequency, director of facilities Ron Brown realized he had a serious problem.

The 45-year-old pipe ran 4 feet beneath a concrete service hallway on the first floor. Excavating to replace it would be expensive and interfere with daily operations. A recommendation sent Brown to Nu Flow.

“We inspected the line, but couldn’t see much because the pipe was full of water, grease and debris,” says Nu Flow regional project manager Nick Ghosn. “Our biggest challenge was the unknown in this dark, dirty, forgotten part of the casino.”

To rehabilitate the line, Ghosn chose the Nu Drain start-and-stop pull-in-place structural lining method, which eliminated reinstatements and was more economical. The eight-day project dealt his crew a few surprises.

discovery period“We were told to expect a straight run of ABS pipe,” says Ghosn. “Our two-day inspection proved otherwise.”

The SeeSnake camera/locating system (RIDGID) revealed 20 feet of 4-inch cast-iron line running from the street clean-out to a 90-degree elbow. From the bend, 4-inch ABS pipe ran 130 feet before upsizing to 6-inch ABS, which ran 140 feet to the upstream clean-out. Both lengths of pipe had two pairs of 45-degree elbows that dropped elevation 10 feet.

The number of turns in the pipe and its condition made additional access points necessary. Per Ghosn’s specifications, Brown hired a contractor to install two downstream clean-outs and excavate a 4-foot-square hole midway in the line where it upsized. Everyone worked in the hallway during the day, yet most staffers were unaware of the activity.

Ghosn’s crew also found a communal line serving three second-floor kitchens at the upstream end of the grease pipe. He engineered a bypass system, then the casino maintenance staff installed it. At the first-floor level, a 4-inch line from the main buffet dishwashing room and a 3-inch line from the employee dining room teed into the upstream end.

getting a clear pictureOn the third day, the team parked their truck and a 300-gallon trailer-mounted jetter (US Jetting) at the curb by the street clean-out. They spent the morning using a pneumatic heavy-duty Micro-Cutter cable machine (Nu Flow) and various cutting tools to break up the grease in the downstream segment. That afternoon, they jetted the debris, collecting it in a 16-gallon wet/dry vacuum (RIDGID).

Technicians repeated the process the next day, cleaning upstream from the access pit. “The door at the end of the hallway was 15 feet from the curb and our jetter,” says Ghosn. “We dragged in the hoses and went to work. The only reason we ever entered the kitchen was to grab a bite to eat.”

As the pipe’s interior walls emerged, the camera detected a crack running along 80 percent of the crown. Although technicians saw evidence of exfiltration, erosion was not an issue. “The line had a Heat Trace cable to warm the pipe and keep grease flowing,” says Ghosn. “Heating the pipe caused it to crack.” During two and a half days of cleaning, workers removed food, kitchen utensils, plate fragments, 10 pounds of broken glassware and a dozen pieces of flatware from the pipe.
