Nu Flow successfully completed a pipe-retrotting project at a Naval Base in San Diego without the need to destroy

the base’s runways. Nu Flow technicians used our epoxy coating technology to upgrade the durability of the

compressed air piping system and extend its useful life.

Project: Rehabilitate the failing

compressed air system used to start

ghter jet engines without causing

destruction to the runways.

Customer and Site: The tarmac for 

the Naval Air Station at the North

Island Naval Base on Coronado Island,

California, commissioned in 1917. The

NAS North Island is part of the largest

aerospace-industrial complex in the

U.S. Navy and in 1963, the station was

ofcially recognized as the “Birthplace

of Naval Aviation.”

System: More than 1,300 feet of 6”

steel pipe approximately 4 feet under 

the concrete runway, as well as eight

3” risers to each of the F-18 aircraft

canopies. This pipe system delivers

compressed air used to start the

engines on the F-18 ghter jets.

Situation: The 6” steel pipe line had multiple leaks and breaks that eventually prevented the three compressors

from maintaining adequate air pressure, even if they ran non-stop. The U.S. Navy looked for a long-term solution

that would create minimal disruption and demolition to the runway.

Solution: Nu Flow used a proprietary process to clean the line while removing the corrosion and oil sludge build-

up in the pipe. Using the existing vault access points to the pipe, Nu Flow retrotted the pipe with a hybrid solution.

First, technicians installed Nu Flow’s structural liner to

repair the broken section of the pipe. Once completed,

Nu Flow applied a double coat of their blown-in epoxy,

creating a barrier coating on the inner pipe walls. The

two-part epoxy is a product of Nu Flow Technologies

Inc., manufactured in North America. The need for 

digging was unnecessary and in this case, the runway

was left untouched and disruption to Naval ight

operations was avoided.

Compressed air systems are common in commercial

and industrial environments. Whether you are

experiencing problems now or are interested in

preventing the inevitable failure of your plumbing

system, Nu Flow is available to restore your peace of 

mind.

Nu Flow cleaned and lined more than 1,000 feet of 

pipe located beneath the concrete runway without

digging or disrupting Naval ight operations.
