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 What is SDR in HDPE pipes?What is SDR in HDPE pipes?In HDPE pipe, "SDR" indicates the ratio of outside diameter to wall thickness. The bigger the thickness of the pipe wall, the smaller the SDR value and the higher the strength of the pipe. For example, if the outer diameter is 315 mm and the wall thickness is 18.7 mm, the SDR ratio is 17, that is SDR 17.Reference krahpipe.net/What-is-SDR-in-HDPE-Pipes-id3412275#:~:text What is pipe working pressure?What is pipe working pressure?"Working pressure" is defined as the pressure that a pipe, tubing, or other part is under during standard operating procedures.How to Calculate Working Pressure Sciencing What is the temperature rating of PVC pipe?What is the temperature rating of PVC pipe?PVC pipe is usually rated as being able to withstand temperatures between 140 to 160°F. The trick is to insure the heat trace cable will maintain the contents within the PVC pipe at a desired temperature, but never to approach the pipe rating temperature.PVC - Heat Trace Cable - Plastic Pipe Freeze Protection

According to standard of HDPE Pipes testing temperatures must be less than 100 degrees F (38 degrees C). At temperatures above 100 degrees F (38 degrees) still test pressure temperature must be reduced. Before applying of hdpe pressure testing time may be required for the test medium and the test sample to temperature equalize.HDPE Testing Procedure - Insulated pipe and fittingsBefore applying test pressure, allow time for the test medium and the pipe test section to equalize. At temperatures above 100°F (38°C), test pressure must be reduced.
