After the PE pipe is filled with water, the air in the pipe is first discharged. The pressure change duration shall not be less than 10min, and the pressure should be filled with a manual pump. 1h after the surge tube exceeds the required test pressure, the test gas pressure shall not exceed 0.06MPa. It uses a PE pipe to charge compressed gas, the pipe is additionally equipped with a refrigeration shaping sleeve, so that the surface of the pipe fitting is pasted in the shaping sleeve to quickly refrigerate and harden the bottom and set the external specifications. The pipe fitting is evenly drawn out by the traction device. Shandong PE pipe manufacturers

PE pipe is not easy to rust, can replace the general iron water supply pipe fittings. Due to the limitations of other pipe fittings, many PE pipes are now used to replace the previous pipes. Because of the friction resistance of PE pipe and the superior performance of the insulation layer, coupled with its own resistance to gas pressure and good pull and push, now in many power engineering assembly line construction process, often used.

PE pipe specifications are all refers to the diameter, matching the difference in pressure level, the thickness of the water supply pipe may be different. Users can choose their own interface mode according to the pipe diameter, pressure, application site and other places. In the underground environment of PE pipe, due to the influence of underground movement and end load, it is necessary for the water supply pipe buried in the soil to have good flexibility.

PE pipe is not transparent, pipe fittings according to the size of S5, S4, S3.2, S2.5, S2 five series of products. The pipe series S has a clear relationship with the nominal diameter, and the pipe series S is used for pipe specifications. The key test pipe nominal outside diameter, average diameter and the thickness corresponding to the pipe series, pipe socket connection specifications and the corresponding nominal outside diameter.

The unique flexibility of PE pipe also makes it resistant to underground movement and top bearing capacity. From the surface, plastic buried pipe in the strength and stiffness than cement drainage pipe and metal hose, but in practice, plastic buried pipe belongs to the "flexible pipe", under the appropriate design and paving, with the surrounding soil bear the bearing capacity.
