Testing the 18” diameter gas header, which operates under vacuum. Pressure testing of HDPE pipes takes place at almost every landfill lining system and landfill gas collection system construction project. The pipes must be tested to make sure the fusion welds Puhui Pipe manufacturer in China
Identifying pressure spikes through a pressure test The documentation of measured values during the testing of pressure profiles in plant can also help to identify pressure spikes. To determine the cause and intensity of pressure surges, it may be useful to access Puhui Pipe manufacturer in China
PE Testing and Commissioning Field pressure testing PE pipelines may require special consideration due to the creep response and stress relaxation of the material. When a PE pipe is sealed at test pressure, there may be a pressure decay, even in a leak free
