Steel has traditionally been the material of choice for fire sprinkler system pipes and fittings worldwide. Steel’s advantages like its very high melting point and easy availability made it a logical choice.
What materials are used to make sprinkler?
These include aluminum tubing, plastic, and rubber . The aluminum forms the oscillating arm. The base of the sprinkler is generally of injection molded plastic. The motor or the mechanical head that forces the sprinkler to oscillate is generally of plastic gears as well.
What material are fire sprinklers made of?
The most commonly used steel pipe for sprinkler systems is black steel pipe . Copper tubing is another piping material listed for sprinklers in NFPA 13. Also, plastic pipe (namely, CPVC and PEX tubing) is permitted for certain types of sprinkler systems.
Can fire sprinklers be PVC?
Plastic pipe fire sprinkler systems are available in CPVC and PEX from several manufacturers and are designed to be installed in certain residential and/or light hazard applications. Plastic systems are specially listed for use in wet fire sprinkler systems.
Why is fire sprinkler pipe orange?
A slick, impermeable surface keeps bacterial contamination at bay in both pipes, although the extra chlorine in CPVC adds an additional layer of protection. ... The CPVC pipe and fittings used in fire sprinkler systems is orange.
Which pipe is best for sprinkler system?
Polyethylene is the best bet for special situations in areas where sprinkler and irrigation systems require flexibility. Both types of pipe are durable and can withstand many elements in the environments where they excel.
What is Victaulic coupling?
Victaulic couplings, or mechanical grooved couplings (also called mechanical pipe joining systems), are components that join mechanical pipes together to create a watertight joint . ... The metal housing – a sleeve of sorts – is then placed over the gasket and joined pipes and tightened with nuts and bolts.
Which pipes are used in fire fighting?
Fire fighting pipe is a type of normal carbon steel pipe used to convey fire suppression agent such as water or gas. Usually it is red in color. But light-wall pipes have a galvanized exterior of a silvery appearance. Installation of red steel pipe is limited to wet pipe sprinkler systems only.
What size pipe is used for sprinklers?
When you install a sprinkler system, you might use PVC or polyethylene piping to deliver water to the sprinkler heads. If you use PVC, the typical diameter of the pipes is between 1/2 inch and 2 inches .
Can you use copper for sprinklers?
Copper types K, L, or M can be used for fire sprinkler systems, offering lighter weights and increased flexibility as the diameter shrinks.
Can I use PVC instead of CPVC?
CPVC and PVC Similarities
It is safe to use CPVC in applications where PVC may be used. Both PVC and CPVC have been deemed safe for potable water transport, i.e. cooking, drinking, and bathing water, but only plumbing that has received ANSI / NSF 61 certification should be used.
Is CPVC and PVC the same?
CPVC is altered by a free radical chlorination reaction that effectively increases the chlorine content of the material. CPVC is also a thermoplastic that is molded into many of the same products as PVC . This difference in makeup allows CPVC to withstand a wider range of temperatures.
Is PVC pipe fire resistant?
Though PVC (polyvinyl chloride) is naturally fire-resistant . It contains a large number of chlorine ions in the molecular structure and these are particularly difficult to break off when exposed to heat. If it does catch fire, PVC has a particularly slow spread of flame.
Is CPVC expensive?
CPVC is a more expensive product so it is usually the chosen material for hot water applications, while PVC is used for cold water applications like irrigation and drainage. So, if you’re stuck between PVC and CPVC on your next project, remember to take into account at least two important factors: temperature and cost.
What is orange pipe used for?
| Red Electric power lines, cables, conduit, and lighting cables | Orange Telecommunication, alarm or signal lines, cables, or conduit | Yellow Natural gas, oil, steam, petroleum, or other gaseous or flammable material | Green Sewers and drain lines | Blue Drinking water |

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.
