Guidance for Field Hydrostatic Testing Of High Density hdpe pipe pressure testing procedure in norway

The factors which affect the hydro-testing of HDPE pipe during commissioning procedures are the creep characteristics of the PE pipe, the percentage volume of trapped air in the pipeline, and temperature variations. The self-limiting creep expansion of HDPE pipe is normal behavior for plastic materials when an What is pressure testing of plastic pipes?What is pressure testing of plastic pipes?Pressure testing of plastic pipes, especially PE, is complicated because the pipe material creeps under pressure therefore the pressure reduces without any leakage so results can be misleading. A water loss method is therefore not practical. This is true for all PE pipes irrespective of the method used to install them.Testing Inspection - HDPE PE pipe (polyethylene pipe) What is the leak pressure for polyethylene pipe?What is the leak pressure for polyethylene pipe?For leak testing purposes, the maximum allowable test pressure in polyethylene pipe is 150% of the pipes design pressure rating for the application and the application service temperature. Do not subject lower pressure rated, non-polyethylene parts or devices to pressures above their pressure rating.Technical Note 802 Leak Testing of Polyethylene Pipe For hdpe pipe pressure testing procedure in norway

What is the procedure for PE pipe?What is the procedure for PE pipe?This will result in a drop of pressure or require the system to be topped up' to maintain the required pressure. The test procedure for PE pipe must include a period of time to allow the pipe to stabilise or should include a method whereby the pressure drop due to pipe expansion is calculated to discriminate from the pressure drop from leakage.Pipe testing procedures - HDPE PE pipe (polyethylene pipe)

When we test, we pressurize the pipe to 120 lbs, hold for a hour. The pressure always drops as the pipe expands. Then we drop the pressure to 30 - 40 lbs. Then we watch the pressure over the next hour.
