Therefore, we need to strictly control the PE pipe when testing it. Next, we will introduce some related methods. After the air in the PE pipe to be tested is excluded, the pressure is increased to the required pressure value at a steady boosting speed, the pressure gauge should be pe pipe pressure test procedure in namibia

Modified pressure rebound method.DISINFECTION, PRESSURE TESTING AND Pressure test The test pressure for any MDPE/HPPE pipes should be 1.5 times the pressure rating of the pipe. For example, if the pipe the customer has laid is rated at 8 bar, the test pressure should be 12 bar. If the pipe is rated at 10 bar the test pressure will need to be 15 bar. This applies to both water mains and service pipes.

USA. 1988Hydrostatic pressure testing of PE pipelines (handbook) as pe pipe pressure test procedure in namibiaThis is known as the 10 Minute Test. All joints are left exposed and checked visually during the test. Test pressure is 1.5 times the pressure rating of the lowest rated component in the system. Flow and pressure are logged throughout the test. Pass/fail criterion is based on the flow of water required to maintain the test pressure in the pipe.Hydrostatic test of polyethylene pipeThe test pressure is always a combination of the pump pressure and the pressure difference between the height of the water (head) inside the polyethylene pipe (for every 10 meters, the difference in pressure height is about 1 bar), so the barometer should be at the lowest point at the beginning of the tube which has the highest pressure.

This pressure is variable - but fairly constant for houses close to each other on the same feeder pipe. This pressure depends on where the house is located on the municipal supply line, and also on the water pressure available to the authority supplying the water.PE Testing and Commissioning - Vinidex Pty LtdAll openings must be sealed prior to testing, and air pumped slowly into the PE pipeline until a test pressure of 50KPa is reached. This test pressure should be maintained for a minimum time of 3 minutes, and if no leaks are detected, or pressure loss observed on the gauge, the air supply control valve should be turned off and the test pressure held for a minimum time of 1 minute.

C) The limits of the pressure test and test pressures shall be as follows. The service connection to the main need not be included in these tests if it is not feasible to do so. However, it must be given a leakage test (i.e., soap tested) at operating pressure and documented as part of the pressure test when placed into service (See Section 12.0).Pressure Tests of Piping systems-Hydrotest Vs Pneumatic TestIf the fluid handled is vapor or gas then the internal design pressure dictates the testing method. For pipe design pressure 10 bar and above the pipe is hydro tested. For pipe design pressure below 10 bar pipe is pneumatically tested. If fluid handled is stream then hydro testing is suggested.Pressure testing of drinking water pipes Norva24Methods for pressure testing The method for pressure testing also depends on the type of pipes to be tested.
