A fire protection pipe is a component of a fire protection system. Water is supplied to sprinkler heads from the water supply by means of a fire protection pipe. In a dry pipe system, the fire protection pipe remains dry until the alarm is tripped, causing valves to fill the pipes with water. Other types of fire protection systems have one thing in common: they all require fire protection pipes to supply water to the fire.

That’s because unless you keep PVC pipe under intense heat and flame, it doesn’t burn very well at all. PVC pipe needs a temperature of around 734 degrees Fahrenheit (390 Celsius) to catch fire which is quite high. Other building materials, for example, wood, have much lower burning temperatures. Wood burns at around 500 degrees Fahrenheit.
