PE pipe fittings Common quality problems and solutions:

PE pipe fitting Surface ripple

Causes: The size of the seal ring is not appropriate during production, resulting in vibration and ripples on the surface. Another condition is insufficient cooling.
Solution: check the size of the vacuum groove seal ring, and replace it if it is small http://www.zbpeg.com Or properly reduce the vacuum degree of the vacuum tank near the front section and increase the vacuum degree of the second section. Increase the sizing sleeve water inlet or increase the distance between the die and the sizing sleeve.

Pits appear on the inner wall surface of PE pipe fittings

Cause: between die and core die http://www.hdpegc.com The inner wall is not cleaned up, the local temperature is too high during production, which leads to aging, or the raw materials contain impurities.
Solution: Check whether the raw materials are clean before production. If they are not clean, they must be cleaned. Check the temperature sensor regularly.

The surface of PE pipe fittings is not smooth

Causes: improper melt temperature or raw material problems.
Solution: Adjust the melt temperature or change the raw materials before production.

There are scratches on the outer surface of PE pipe fittings

Causes: There are sand and stones on the calibrating sleeve, support plate or sealing ring.
Solution: Regularly clean the calibrating sleeve, support plate or sealing ring.
