2. The elongation at break of the PE water supply pipes is not less than 350%. Our test results showed that the elongation at break is more than 450%.
3. The elongation at break of the gas pipes used for buried PE pipes shall not be less than 350%. Our test results showed that the elongation at break is more than 450%.

Hydrostatic testing machine
2. Check the hydrostatic strength of the PE water supply pipe. The standard requires 5.5MPa as the hoop stress, and the test pressure is calculated according to the formula. In the 80±2°C water temperature environment, the pressure is maintained for ≥165h without leakage and cracking. Our test results showed no leakage and rupture after 165 hours of pressure maintenance.
3. Detect the hydrostatic strength of PE buried gas pipes. The standard requires 5.4 MPa as the hoop stress, and the test pressure is calculated according to the formula. In the 80±2°C water temperature environment, the pressure is maintained for ≥165h without leakage and cracking. Our test results showed no leakage and rupture after 165 hours of pressure maintenance.

Electric thermostat
2. Check the PE water supply pipe at 110°C for the specified time. After cooling at 23°C, measure the distance between the marking lines before and after placing the sample in the oven. The standard stipulates of the length change rate is ≤ 3%, and the length change rate for our PE water supply pipes is ≤ 2%.
3. Test the moisture content of the buried gas PE pipe, Its standard is ≤300mg/kg, and our test results are all ≤260 mg/kg.
