Temperature/pressure derating

The rated working pressure of an HDPE pipe is determined at 20°C. Where the operating temperature of the fluid in the pipe exceeds 20°C, the pressure rating of the pipe has to be de-rated in order to maintain the designed safety factors of the pipe.

HDPE pipe is not recommended in applications where the fluid temperature exceeds 50°C.
