Pipeline Support Services Fire Suppression Projects. Pipe rehabilitation using non-destructive techniques.
Fire Suppression Pipeline Rehabilitation As with all mechanical systems, fire suppression system pipes have an expected useful life before repairs or replacements are required. Nu Flow’s epoxy coating can be applied to repair damage and increase the life expectancy of fire suppression and sprinkler systems. A growing list of companies have used Nu Flow to preserve and protect their fire suppression pipes while avoiding the cost and disruption of system replacements.
‘Nu Line’ Technology Patented ‘blown-in’ epoxy lining system. Non-invasive process that uses epoxy to coat the inside walls of pipes without destruction to interior or exterior surfaces of building structures, hardscape, or landscape. A long term solution to prevent corrosion and leaking. Restores and preserves the life of the existing pipe system. For use on all pipe materials ranging from 13mm (½”) to 300mm (12”).
Common Applications Fire sprinkler and suppression systems
Gas service lines Compressed air systems Hot and cold potable water systems Lead pipes HVAC/Hydronic and chiller systems Process, Conduit & Chemical piping

Case Study: Washington DC Metro Stations. Eight stations in the Washington Metropolitan Area. 90m (300ft) of fire suppression mains at each station consisting of ductile, black iron and galvanized pipes. Diameters ranged from 40mm (1½”) to 150mm (6”). Aging pipes suffered from leaks and corrosion build up that could jeopardize the performance of the system.
Case Study: Washington DC Metro Stations. Significant downtime of the subways operations would have occurred if a pipe replacement was chosen. Nu Flow restored the aging system by applying an even layer of epoxy to the internal walls of the pipe. Preserved and extended the lifespan of the system and saved the customer from the cost and logistics of repairing and replacing it.
Case Study: San Diego Yacht Club, California. Over 200m (700ft) of fire suppression supply pipe located several feet beneath the club’s carpark. 150mm (6") diameter pipes made of ductal iron and other miscellaneous materials. Leaks and corrosion present in the system. A long-term, minimally disruptive solution was sought.
Case Study: San Diego Yacht Club, California. Traditional repipe would have required the carpark to be excavated, which would have been unsightly in the pristine property. Nu Flow successfully rehabilitated the underground fire supply pipes without inconveniencing the yacht club’s visitors. The failing fire suppression supply lines were cleaned and lined within a week. This was done using two access points. During the work, 95% of the carpark was open and temporary water was available for the pipe system so that it was still functional.
Case Study: Grimaldi Forum, Monaco. Approximately 600m (2,000ft) of fire suppression iron mains with a 150mm (6") diameter and a large number of 90° elbows. Pipes were located above, and hanging from, ceilings in many of the building’s rooms including theatres and storage rooms.
Case Study: Grimaldi Forum, Monaco. Inspection of mains revealed corrosion and the customer feared this would lead to leaks and expensive damage. Pipe replacement would have been extremely expensive and caused several months of disruptions. Schedules for the theatre, opera, and conference rooms would have to be postponed and changed. Existing access points in the mechanical room were used to clean and line the fire suppression pipes using Nu Flow’s Nu Line technology. The project was completed in a couple of weeks. The patented Nu Line process prevented any demolition or disruption to the property, saving the customer a lot of money.
Case Study: Fort Drum, New York. U.S. Army aircraft hangar at Fort Drum in New York, occupied by numerous attack helicopters. The aqueous film-forming foam (AFFF) distribution system consisted of 420 open sprinkler heads on six deluge systems.
Six bays, each with its own fire-suppression station. Totalled over a mile of 25mm (1”) to 150mm (6”) black iron pipes.
Case Study: Fort Drum, New York. Pinhole leaks, failing joints and tuberculation in the AFFF system were causing failures and false alarms. Nu Flow used existing sprinkler heads to access, clean, and reline the fire-suppression deluge system. Renovate and protect a fire-suppression deluge system using Nu Flow’s patented epoxy coating. Successfully completed the project without interrupting military operations.
Case Study: Sandia National Laboratories, New Mexico. An engineering and science lab operated by Sandia Corporation for the U.S. Department of Energy’s National Nuclear Security Administration. A high-security campus on Kirkland Air force Base in Albuquerque, New Mexico. 150m (500ft) of fire suppression main with diameter of 150mm (6”). Ductile and cast iron pipe running six feet below the foundation and into the riser rooms of each building. The pipe had 90° elbows and an 80m (260ft) section was below finished concrete and interlocking pavers.
Case Study: Sandia National Laboratories, New Mexico. Microbiologically Induced Corrosion (MIC) was causing pinhole leaks, tuberculation and flow reduction. Nu Flow sandblasted the inside of the pipes to remove the corrosion in the system. Once complete, the pipes were rehabilitated by applying two evenlycoated layers of epoxy inside the pipe’s walls.
A pressure test was carried out upon completion of works to ensure the pipes were leak free before reconnecting the system.
Case Study: Ballylumford Power Station, Northern Ireland. Ballylumford power station is a natural gas-fired power station in Co. Antrim, Northern Ireland. Owned by AES Bord Na Mona, it is Northern Ireland’s largest power station. 355mm (14”) fire suppuration system. Significant underground section of the system was leaking. Nu Flow successfully rehabilitated the pipeline without causing any disruption or damage to the busy power station.
Case Study: Howard Hughs Medical Institute, Maryland. Fire suppression pipeline located underneath the walkway between two dormitory buildings at the world renowned research centre. Cracked and leaking 100mm (4") diameter ductile iron pipe. A repipe or reroute would have caused a large expense and inconvenience for the medical centre and taken several months to complete. A structural liner was installed using existing access points to ensure all breaches in the pipe were covered. Our patented Nu Line system was then installed to prevent corrosion and other failures from occurring in the future. Digging was avoided during the entirety of the project and no disruption was caused to there was not any disruption to the research facility’s normal operations.
