Fireline refers to a type of water pipe system that is used to extinguish fires. Underground pipes attach to fire hydrants or fire suppression systems and deliver pressurized water at an accelerated speed.

Fireline is installed by pipeline contractors. The process is similar to other types of water pipe and entails excavating the land, preparing trenches, laying pipe, and attaching components.

Underground fireline pipes may require more water pressure compared to domestic water pipes. For the most part, a "hot tap" method is commonly used, depending on governing authority over the fireline. The other method is called a "cut-in" connection.

Hot taps are the preferred choice for customers because they do not affect the pressure of municipal water mains. For the pipeline construction expert, this method needs a more cautious approach in the handling of the pipe than the cut-in method. Extreme caution is necessary to avoid damaging the water pipe main. A live or "hot" water main that is still active and running under high water pressure, it is extremely sensitive to how it is handled, compared to when the water line is not pressurized.

The drawback of using cut-in method is that water main valves will need to be shut off, and a "fire watch" alternative method of fire prevention will need to be conducted by the fire department, and other coordination efforts by contractor and project owner, over a given property or project site, until the water main valve is turned back on again.

Fireline systems also need various components that convey water through the system via fire hydrants or internal sprinkler systems. Every element of these systems must be installed in accordance with state and local regulations, such as the National Fire Prevention Authority (NFPA) codes, as well as maintained on a consistent basis, to ensure proper working order in the event of a fire.

Municipal fireline systems make use of underground and aboveground systems that are pressurized for maximum water flow. Once installation is completed, pipes need to get flushed and rid of any debris or sediment that could cause interior fire sprinklers to fail later on.

Most residential communities utilize fire hydrants, while commercial buildings are protected by interior fire suppression systems. Commercial systems are sometimes self-contained and used solely for that building. Commercial systems are more sophisticated than residential systems and make use of multiple components including hydrants, sprinklers, post indicator valves, and fire department connections (FDC).

FDC devices, usually attached to buildings, or standing nearby, are needed in order for the fire trucks to feed water from a nearby fire hydrant into the specific building connected to the FDC. FDC's are located above ground which allows firefighters to easily connect their fire truck from the fire hydrants to the FDC's.

Underground fireline pipes are primarily manufactured from polyvinyl chloride (PVC) or metal ductile iron pipe (DIP). Materials used in fireline construction must comply with regulations of Factory Mutual (FM) Research Corporation or Underwriters Laboratories (UL).

Municipal fireline construction materials are required to pass through further testing to comply with county codes pertaining to plumbing and mechanical engineering. Most often, these codes are established by local fire departments.

Whenever fireline is installed it is vital to employ experienced fireline construction contractors, such as Kana Pipeline. Our team of dedicated professionals excels at installing new fireline systems for all types of new construction projects.

We are experienced in installing municipal, commercial, institutional and industrial fireline systems. Most pipeline contractors have a dedicated team of fireline installers who work on fire suppression systems.

Kana Pipeline has been recognized as an industry leader in this field of underground pipeline construction. If your municipality or business is in need of fireline services then Kana Pipeline should be your first choice.
