High density polyethylene (HDPE) pipe and piping components have been used successfully and safely for natural gas distribution around the world for several decades. The primary concerns for a 50 year life for buried HDPE piping Puhui Pipe manufacturer in China

Typically, for ductile, viscoelastic HDPE pipe, the hoopstress during hydrotest should exceed 30% of the specified minimum yield stress (SMYS) but remain less than 42% of the SYMS. The following test pressure ratios for HDPE pipe may be used, as decided by the pipeline owner, depending upon the owner’s needs and test objectives.

pressure of 100 psi and a surge pressure of 150 psi. SDR 17 HDPE pipe has a wall thickness of approximately 2.3 inches with an OD of approximately inches (1,000 mm), leaving little room to maneuver it within the existing


The determination of the required testing pressure is based on the MOP (maximum operation pressure) and would result in a testing pressure of only 4.2 bar for a MOP of 10 bar. The PE100+ Association takes that into consideration and raises it''s requirement in terms of the testing pressure in the S4 test up to minimum 10 bars.
