Hydrostatic pressure test
In order to assess the product's strength against hydrostatic pressure test is carried out. , placed under constant internal pressure.
Any defect in the samples (cracking, bulging, local swelling, leakage and fine cracks) to mean the product has failed.
Burst pressure test pipes
Tube without cracking or bulging with the longitudinal slot is unsafe for consumption.
Tips for test pressure polyethylene pipes
The purpose of this test to measure the internal pressure resistance of thermoplastic pipe is fixed at a specified temperature.
This test is carried out under the following conditions:
Water as a reference fluid inside the pipes
Water, air or a liquid identified as the environment around pipes
This method can be short-term or long-term tests at different temperatures to be used.
Type of burst test (short test):
This type of inspection is a test to determine the type of polyethylene pipes is done. The results of this test sample behavior when placed in the short term will be determined by hydrostatic pressure.
In this test-tube floating in a basin with a constant temperature, placed under increasing internal pressure, so that over time 60 to 70 seconds and then burst tube is inflated.
2. Hydrostatic pressure test (long term test):
. After a set time samples should have a crack, swelling, leakage or any shortcomings are.
Devices for testing:
which is kept at a specified temperature
