Pipe Lining Delivers

Neither flooding, nor backups, nor sewer smells stays these couriers from the swift completion of their appointed rounds. Learn how pipe lining was the clear solution for this Nevada post office.

Mail delivery is a non-stop 24-hour operation. After decades of round the clock production, a mail sorting facility in Nevada needed some major repairs. The building’s outdated plumbing infrastructure was causing ongoing issues that were affecting the employees. With thousands of businesses and households relying on the postal service daily, shutting down for repairs was not an option.

When assessing the project, the contractor knew the sewer pipes would need a major overhaul. The pipe system is located under a concrete subfloor that is fitted with large mechanical equipment that sprawls throughout the 500,000 sq ft building. Replacing the pipes would be next to impossible without disrupting operations and would likely take months to complete.

Pipe lining was the clear alternative to fix the pipe problems without disrupting the daily service of the post office. The mechanical contracting company knew they needed to an expert to rehabilitate the aging system, so they called a NuFlow Certified Contractor. They had previously worked with the NuFlow contractor on a similar project and trusted them to not only repair the pipes, but to complete the project in a timely and professional manner, so they could stay on track for the overall project timeline.

The crew conducted a thorough camera inspection of the entire pipe system, creating a map of the infrastructure with detailed assessment of the condition of the pipes. They planned a phased approach to tackle the project, starting with cleaning the pipes to remove years of sludge and debris that had built up on the inside. The technicians then lined the pipes with an epoxy resin, creating a structural “pipe within the pipe”, that will resist breaks or corrosion for many years to come. When the project was complete, the contractor lined a total of 1400 linear ft of cast iron pipes in 4, 6, and 8 inch sizes. Like the mail, the NuFlow Certified Contractor completed the project on time so they could finish the project of upgrading the facility to a modern day work place.

City of San Diego

NuFlow completed a large fire training center pipe-lining project in which they renovated the pressurized water system with its effective alternative to traditional pipe replacement. The work was done in three stages, avoiding disruption to the ongoing daily training.

Project: To coat fire suppression water lines consisting of black steel pipes of various sizes.

Customer: The City of San Diego, CA, which manages the Naval Base San Diego’s Fire Training Center, a decommissioned U.S. Naval Base.

Site: Six buildings in the Training & Safety Division Facility housing a state-of-the-art computerized fire simulator built for the U.S. Navy. The center trains more than 35,000 military personnel each year and is also used to train municipal firefighters and civilians.

System: Over half a mile of black steel pipe ranging from 1 1/2” to 6” in diameter including multiple elbows, tees and transitions in pipe diameter.

Situation: Several buildings at the facility were experiencing multiple plumbing leaks. Re-piping was considered but rejected due to high costs and lengthy down time.

Solution: NuFlow coordinated the project by stages and formulated a work schedule that promoted clear lines of communication with the naval base personnel regarding the ongoing coating work. After using compressed air and garnet to clean the inside of the entire piping system, NuFlow applied an evenly coated layer of its epoxy to stop leaks and prevent corrosion.

Washington DC Metro

NuFlow lined over 1 mile of fire suppression systems within the Washington Metropolitan Area Transit Authority. The need to replace those pipes would have required significant downtime and impact on the operations of the subway.

Project: At each of eight Metro stations, coat 300 feet of variously sized fire suppression pipes.

Site: Eight stations within the Washington Metropolitan Area Transit Authority.

System: Fire suppression main for each station consisting of 300 feet of ductile, black iron, and galvanized pipes ranging from 1 1/2” to 6” in diameter.

Situation: The fire suppression systems were showing leaks and corrosion buildup that could jeopardize the performance of the fire suppression system.

Solution: NuFlow saved the customer from the high cost and complex logistics of repairing and replacing the entire system.

California Chooses NuFlow Pipe Retrofit During Remodel

In a situation where a pipe is located underneath or within a building, pipe replacement is not an optimal solution, as it causes disruption to ongoing operations. NuFlow has the technology to rehabilitate pipe systems without digging trenches or access points by using their patented NuFlow process.

Project: Restore California State Office Building’s failing rain leaders.

Customer: The State of California, Department of General Services, which serves as business manager for the State of California.

Site: California State Office Buildings 8 and 9 located in Sacramento, CA.

System: Galvanized rain leaders on the exterior decks of the two 17-story buildings. The project included 120 five-foot segments and 120 ten-foot segments of 3” drain pipe. Each pipe extends from a surface drain directly into the concrete structure.

Situation: Both office buildings had corrosion and buildup in the rain leaders, causing the pipes to leak within the concrete that encases the pipes. Traditional repairs would have required the removal and reconstruction of a significant portion of the concrete building to access the pipes. A pipe retrofit from NuFlow was chosen as part of an overall remodel of the building.

Solution: NuFlow saved the customer from the cost and logistics of replacing the system, which would have caused extensive damage to the office buildings. First, NuFlow removed all buildup and corrosion, returning the pipes back to their original diameter. Then NuFlow rehabilitated the pipes with the patented NuFlow process by pulling a seamless structural liner into place through access points on the outside ledge of each floor, greatly extending the pipes’ useful life. The work was performed around the schedule of the state workers to avoid disruption.

Corrosion and leaks are common symptoms of a failing pipe system whether in commercial, industrial, or residential buildings.

Retrofitting pipes without disruption to ongoing operations in the buildings is one of NuFlow’s many advantages.
