Which pipe is best for fire fighting?

Steel Pipe. Steel pipe has long been the mainstay of piping materials for sprinkler piping systems. Steel is considered strong, durable and resistant to fire. With a melting point of about 2,700°F, steel pipe can withstand the heat within a burning building.

What size is fire sprinkler pipe?

The sprinkler pipe size from the water supply source to a sprinkler shall be not less than 3/4 of an inch (20 mm) in diameter. Threaded adapter fittings at the point where sprinklers are attached to the piping shall be not less than 1/2 of an inch (15 mm) in diameter.

What is a fire water line?

A fire service line is the portion of a water line preceding the backflow prevention assembly (BPA), supplying water to the fire sprinkler or private fire hydrant. A fire sprinkler system is the portion following the BPA. Fire protection systems should be protected with a minimum of a double check valve assembly (DC).

What is ERW pipe?

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond.

Should I use PVC or CPVC?

We recommend the use of PVC for recreational use/building, cold water systems, vent systems, and drainage systems. CPVC is recommended for applications where the maximum temperature will exceed 140 degrees Fahrenheit, but stay under CPVC’s max rating of 200 degrees Fahrenheit.

Does PVC have a fire rating?

PVC, like all plastics, is classified as a combustible material per ASTM E 136. PVC has low flame spread, but smoke developed ratings may be as high as 900, so PVC will not pass the 25/50 criteria of the ASTM E 84 test and may not be installed in plenum spaces.

Where is CPVC pipe used?

CPVC (chlorinated poly (vinyl chloride) is a strong and rigid thermoplastic material that is used for hot and cold potable water applications in residential construction. Because of its makeup, CPVC is immune to damage from highly chlorinated domestic water and has a higher temperature tolerance than PVC.

What glue do you use for CPVC pipe?

Unlike green pipe (PPR) and metal pipes, which require heat and flame to weld joints together, FlowGuard® CPVC pipe and fittings use a process called solvent cement welding.
