How to conduct water tightness test for PE pipe fittings
PE pipe fittings can be used in water supply pipeline, in fact, there are upv-c pipe, steel pipe, gray cast iron pipe, glass reinforced plastic sand pipe and nodular graphite pipe.
The test pressure for the watertightness test of PE pipe fittings shall not exceed the pipe pressure grade, or 1.5 times of the lowest pressure grade fittings in the system. When the pipe pressure reaches the test pressure, it shall keep a certain time to make the test medium temperature in the pipe consistent with the pipe environment temperature. The timing shall start after the temperature and pressure are both stable. In general, the water tightness test should be stable pressure for 24 hours, after the test, if there is no obvious leakage or pressure drop, it is considered to pass the test.
PE pipe fittings are ideal for water supply engineering due to their advantages of low cost, convenient construction, good hydraulic conditions, non-toxic, corrosion resistance, low temperature resistance and mechanical vibration resistance.
PE pipe should be fully prepared before use
PE pipe fittings are widely used in the construction industry, because PE pipe fittings have good advantages, but before the use of PE pipe fittings, should be fully prepared to avoid any problems in the later stage.
Before installing PE pipe fittings, it is necessary to dig trenches, and trench is dug out of the soil to have a reasonable pile up place, and can not be too close to the trench, to have more than two meters of distance. And dig out of the earth to timely transport to the outside, so as not to affect the future work. PE pipe fittings in the construction, must use mechanical operation, with mechanical excavation to the design of the groove at the bottom of the elevation of more than 20 cm, the rest of the part can be invited to dig workers.
In order to ensure the safety of the construction, construction period and construction quality, before the construction must be to the construction of the soil quality, underground water level and other parts of the construction area for full understanding and investigation, so as to ensure that there will be no accidents during the construction!
