Changshu smooth plastic products factory talk about plastic extruder pressure test

Plastic extruder before put into operation for pressure test, pressure test including strength test and water tightness test two. Changshu below smooth plastic products factory talk about plastic extruder pressure test.



when testing generally recommend using water as the test medium. After rule out test of the air inside the pipeline, to stabilize the pressure rise speed to increase the pressure to the requirements of the pressure value, the placement of pressure gauge as far as possible in the test section of the lowest place, stress tests can be done before or after the pipeline backfill, pipeline turns the soil at regular intervals, especially for crawling pipeline, pressure test, pipeline should be fixed in place. Open flange connection parts should be exposed in order to check for leaks.



pressure test of the test pressure shall not exceed the HDPE pipe pressure level or a minimum pressure in the system level parts level 1. 5 times, in the beginning, it should be test pressure value of the pressure rise to stay and enough time to ensure full expansion pipes, a process that requires 2 - After 3 hours, when the system is stable, the pressure rise to work pressure of 1. 1 hour five times, voltage regulator, carefully observe the pressure gauge, and along the tour, if there is no visible leakage in the process of testing or obvious pressure drop, the pipe through the pressure test.
