Introducation:
Evaluating the pressure resistance of UPVC threaded pipe fittings is a key step to ensure their safe and reliable operation in practical applications. Here are some common assessment methods:
Evaluation of pressure resistance
Hydrostatic test
Install the UPVC threaded fittings and seal both ends, then inject water and gradually increase the pressure. Observe the performance of pipe fittings under certain pressures. Typically, the test pressure is higher than the designed working pressure of the pipe fitting to simulate use under extreme conditions. During the test, the pipe fittings should be checked for leakage, deformation or rupture.
Burst pressure test
Under more stringent conditions, bursting pressure tests can be carried out on pipe fittings. This is done by exposing the pipe fittings to pressures far higher than they are designed to work under. Until the pipe ruptures, thus determining its ultimate pressure resistance. This test is usually used for research or special applications to understand the ultimate performance of pipe fittings.
Material strength test
The UPVC material was tested for tensile, compressive and bending strength. The pressure resistance of pipe fittings can be evaluated indirectly. These tests can determine key parameters such as the yield point and breaking strength of the material. Thus, the pressure resistance of the pipe fittings can be deduced.
When conducting the above tests, ensure that the test conditions comply with the relevant standards and specifications. Use appropriate test equipment and instruments. At the same time, the test data were recorded and analyzed. The pressure resistance and impact resistance of UPVC threaded pipe fittings are evaluated objectively and accurately.
