Fireline Contractors

Fireline contractors handle the installation of underground fireline that supplies water to fire hydrants and fire suppression sprinkler systems. Contractors also repair, remove, or relocate systems and monitor condition and positioning of pipes.

Fireline contractors undergo substantial training and usually must be licensed to work on fireline systems. These fire pipe systems work different than domestic or reclaimed water pipe systems because the water in fire line pipe remains stagnant for the most part, because it is least often used. Its only intended purpose is for putting out fires.

One of the most essential elements of fireline is having adequate pressure. When firefighters tap into fire hydrants the pressure needs to be sufficient to push large volumes of water through long sections of hose or supply multiple sprinkler showerheads.

Underground fireline is connected to municipal water pipelines. Most fireline contractors use a hot tap method that allows for water pressure in the main water lines even when in use by the fire department. Others contractors may be required to use a cut-in connection method to connect new underground fireline pipeline, which requires a temporary shutdown of main water lines during the installation of fireline pipeline systems. In such case, local authorities would require a "fire watch" to ensure that local fire departments are put on notice whenever fire suppression systems are temporarily shut down for construction purposes.

Fireline systems are complex systems comprised of pipes, connectors, detector check assemblies, indicator valves, and fire hydrants. Each component has to be synchronized to prevent serious consequences that could literally mean the difference between life and death.

Fireline contractors have to use underground pipeline materials that meet regulations of the fire department having jurisdiction. Most pipes and fittings are constructed from polyvinyl chloride (PVC) and metal ductile iron pipe (DIP).

Fireline materials in most cases have to be approved by Underwriters Laboratories (UL) or Factory Mutual Research Corporation (FM). Materials used with municipal jobs often have to undergo further testing to ensure they meet standards of plumbing and mechanical codes.

Proper installation of fire department connections (FDC) is vital for making certain pressurized water is available to extinguish fires. FDC's are positioned above ground so that fire departments can connect their hoses to fire hydrants or wall-mounted connectors.

Fire hydrants are constructed from cast iron or brass and positioned above the main water pipe connection. Firefighters loosen the large nut on top of the hydrant to open the underground valve.

Fire hydrants also have a connection device that is used to attach the fire hose to a pumper truck. These trucks are used to supply water to all fire trucks at the scene until the hose is connected to the hydrant.

The color and size of hydrants, along with the number of outlets and water flow requirements are governed under local jurisdiction. Most hydrants are bright yellow or red but again will vary depending on which city municipality they are installed.

Residential communities depend on public water mains and fire hydrants to provide suppression services. Industrial and commercial systems utilize a matrix of advanced fireline systems that include dedicated water pipes, fire sprinklers, fire hydrants, and FDC's.

It's vital to work with experienced and reputable fireline contractors that comply with installation and material guidelines and state and federal regulations. At Kana Pipeline, we have a team solely dedicated to engineering and installing fire suppression systems.
