BlazeMaster® Fire Fighting Systems are the most specified non-metallic sprinkler systems in the world

BlazeMaster® Applications

Under BIS | NFPA 13 | UL and C-UL | LPCB | FM

BlazeMaster® CPVC fire fighting system pipe and fittings are listed by the BIS, Underwriters Laboratories (UL and C-UL) and the BRE Global Loss Prevention Board (LPCB) for use in:

  • Light hazard occupancies as defined in the Standard for Installation of Sprinkler Systems, NFPA 13 (regardless of the height of the building).
  • Residential occupancies as defined in the Standard for Installation of Sprinkler Systems in Residential Occupancies up to Four Stories in Height, NFPA 13R.
  • Ordinary hazard installations. Section of NFPA 13 (2016 Edition) and of NFPA 13R (2016 Edition) permit the use of pipe or tube listed for light hazard occupancies to be installed in ordinary hazard rooms of otherwise light hazard occupancies where the room does not exceed 400 ft2 (37 m2). BlazeMaster® CPVC pipe and fittings may be installed in these installations in accordance with the manufacturer’s installation instructions and BlazeMaster® System’s design manual.
  • Residential occupancies as defined in the Standard for Sprinkler Systems in One and Two Family Dwellings and Manufactured Homes, NFPA 13D.
  • Air plenums, as defined by the Installation of Air Conditioning and ventilating Systems, NFPA 90A.4
  • Installation of Private Fire Service Mains and Their Appurtenances, NFPA 24
  • System risers in residential buildings up to four stories in height, NFPA 13R and 13D.
  • See UL Fire Protection Equipment Directory, categories VIWT and HFYH.

Temperature and Pressure Rating

Operates across a wide range of temperatures and pressure

BlazeMaster® fire fighting system pipe and fittings, size ¾ in through 3 in (20 mm to 80 mm) are rated for continuous service of 175 psi (1207 kPa) at 150°F (65°C). Their use is suitable in areas where ambient temperatures are within the range of 35°F to 150°F (2°C to 65°C)

In an area where the temperature will exceed 150°F (65°C), such as an attic, BlazeMaster® CPVC can be installed if ventilation is provided or if insulation is used around the pipe to maintain a cooler environment.

The piping systems must be laid out to ensure the piping is not closely exposed to devices that generate heat in excess of 150°F (65°C), such as light fixtures, ballasts and steam lines.

If the installation is in an area subject to freezing temperatures, the sprinkler system must be protected from freezing. A frozen system will not only be deactivated, but the pressures that may build up can cause the sprinkler heads to open or damage the pipes.

Product Ratings, Capabilities and Material Properties

On par with the best global ratings and standards

Pipe dimensions and weights

BlazeMaster® pipe is produced in SDR 13.5 dimensions. SDR, or standard dimensional ratio, means the pipe wall thickness is directly proportional to the outside diameter. This results in consistent pressure capabilities across all diameters.

The pipe is produced to the specifications of ASTM F442. Fittings are produced to ASTM F437, F438, or F439 specifications depending on the system size and configuration.

The CPVC pipes shall be manufactured in SDR 13.5 and confirm to IS:16088 2012 for use in Automatic Fire sprinkler system and installed in accordance with IS: 15105 , IS: 16088 / NFPA 13, 26 (For underground piping).

SDR, or Standard dimensional ratio, means the pipe wall thickness is directly proportional to the outside diameter. This results in all diameters carrying the same pressure capability.

Thermal Expansion and Contraction

Operates across a wide range of temperatures and pressures

Thermal Expansion

CPVC pipes, like all fire fighting piping materials, expands and contracts with changes in temperature.

The coefficient of linear expansion is: (0.0000340 inch/inch-°F)0.000061 cm / cm °C) and linear expansion is the same for all pipe diameters.

For example, a 25°F (13.9°C)change in temperature will cause an expansion of 1 inch 2.5 cm for a 100 foot (30.5m) straight run of BlazeMaster® pipe.

For most operating and installation conditions, expansion and contraction can be accommodated at changes in direction of the pipe run. However, in certain instances, expansion loops or offsets may be required when installing long, straight runs of pipe.

Thermal Expansion


Pipe deflection

BlazeMaster® fire protection piping is inherently ductile, which allows it to deflect—within permissible limits—around or away from objects during installation.

This ductility allows for greater design freedom, reduce installation time and lower installed cost. The maximum installed deflections for BlazeMaster® piping are as follows, in both feet and meters:
