Chiller Pipe Projects

 Wright-Patterson Air Force Base

The Wright-Patterson AFB is located northeast of Dayton, Ohio, and has a rich aviation heritage. The pioneering work of Orville & Wilbur Wright from 1899 to 1903 enabled them to achieve the first manned, powered flight. After their success at Kitty Hawk, they returned home to Dayton where they perfected their flying skills in early 1900s. The AFB was in need of a trenchless solution when a 4" underground chilled water pipe was found to be broken between two 90 degree fittings. They contacted a Flow-Liner Installer to see if there was a solution that avoided the costly and excessive demolition of the pipe and fittings. The Flow-Liner Installer recognized the challenge in lining through a break in between two fittings and, to ensure a successful project, prepared an in-house "mock up" to test the process. The mock up proved the installation procedure and CIPP product would be a successful fix to their complex issue. After cleaning of the pipes, the Flow-Liner Installers successfully navigated the bends in the pipe, sealing the break and holding the necessary pressure. Quick-Lock seals were used at the pipe ends. See our Flow-Liner Certified Installer's happy customer review below.

"The challenge to line back-to-back 90 degree elbows in the middle of the 140 foot run drove one of your competitors away from the job; we are glad it motivated you to research, prototype and prove you were up to the challenge.  I’ll give you the best compliment I can and spread the word about what a great job you did.  Please pass on my congratulations and appreciation to your team."

Comfort Systems - Cooling Lines

Comfort Systems USA is a leading building and service provider for mechanical, electrical and plumbing building systems. Today, they are composed of more than 35 operating companies in over 140 locations across the United States. A Comfort Systems location found a need for trenchless technology in their cooling lines. A certified Flow-Liner installer was contacted to rehabilitate the pipes.
Two pipes were in need of CIPP. Both were voided of all liquids, cleaned, and lined using Flow-Liner's CIPP Inversion, successfully navigating the 90-degree bends inside the pipes. Flow-Liner End Seals were used to ensure a tight seal and protect the CIPP where it enters the pipes. The customer reported their satisfaction with the project, and recommend Flow-Liner's CIPP to others in need of pipe maintenance and repair.


Rockville, MD Pharmaceutical/South Mountain Mechanical

South Mountain Mechanical, a general contractor for a Pharmaceutical company in Rockville, MD, contacted a Certified Neofit+Plus Installer after discovering leaking supply pipes to a cooling tower. The Neofit+Plus Installer was able to line the 300 feet of the 1-1/2 copper cooling pipes successfully, sealing all leaks and navigating multiple long sweep 90 degree bends located throughout the pipe.

The crew was very professional and courteous, they did a great job for us in a timely manner. The Neofit pipe lining saved us from having to dig up and replace the 1 1⁄2” cooling tower fill pipe, which would have been very costly and inconvenient. -South Mountain Mechanical, Contract Manager


Erie Affiliates - Dayton Federal Courthouse

A Flow-Liner® Certified Installer was contacted by General Contractor Erie Affiliates to implement trenchless technology at the Dayton Federal Courthouse. A leak in the cooling water supply line was discovered. The line ran underneath the parking lot, making this the perfect job for non-invasive trenchless technology. After cleaning the pipe, the Certified Flow-Liner® Installer successfully navigated several bends throughout the pipe and efficiently lined the entirety of the pipe without issue, despite the discovery of a significant belly in the pipe.
"Your crew came on the project and worked professionally and cleaned up after themselves. There was a problem with the existing pipe in that a "belly" in the line caused an excessive amount of water, but the men took care of it without complaint and completed the job in a timely manner." - Erie Affiliates
