PPI Hydrostatic Pressure Testing Manual for HDPE Pipe
The ASME Code for Pressure Pipe, in B31.4, requires hydro-test at 1.25 thetimes the MAOP (maximum allowable operating pressure) for steel pipe. 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.
