Jul. 20, 2022

PE pipe fitting in the production process due to the impact of the environment, will form certain defects on the surface of the pipe, such as rough surface or appearance of groove defects.


If the product surface of PE pipe fitting manufacturer is rough, it may be because the temperature of the main engine head is too high or too low, resulting in rough surface. The core die temperature is low, the body temperature is too low, easy to cause rough inner surface. The cooling temperature is too high and the surface is rough. Reduce the cooling water temperature, PP-R optimal cooling water temperature of 20 to 30 degrees Celsius. In this case, the PE pipe fitting manufacturer should check the waterway, check whether there is blockage and insufficient water pressure, check whether the heating ring is damaged, check the performance of the raw material, consult the raw material supplier, clean the temperature of the mold core, if the temperature is higher than the mold section, open the core temperature adjustment device, check and clean the mold whether there are impurities.

And if the appearance of pipe groove, PE pipe fitting manufacturers should check and adjust the sizing jacket water curtain outlet, pressure balance, adjust the spray nozzle Angle, make the pipe cooling uniform, check the sizing jacket, cutting machine and other objects whether there are sundries, burrs.


Repair method of PE pipe fitting:

When the damaged part of the outer wall of PE pipe shows broken pipe wall or holes within 0.1m in length, use a scraper to completely remove the broken pipe wall or holes. Clean the surrounding parts within 0.05m with ring ketone, and brush the plastic adhesive with good water resistance. Then from the same pipe corresponding parts to take the damage area of 2 times of the arc plate, the inner wall coated with adhesive buckle paste in the damaged parts, fixed with lead wire binding. If there is rib on the outer wall of the tube, remove the rib within 0.05m around the damaged part, scrape away without rib marks, and take the same method as above to remedy.

When the outer wall of PE pipe produces local or small part cracks or holes within 0.02m, the water can be removed inside the pipe first, clean the damaged part with cotton yarn, and then brush the base surface with ring ketone, brush the plastic adhesive with good water resistance; The plates of similar shapes and sizes are taken from the corresponding parts of unused pipelines, and bonded, wrapped and fixed with geotextile, and the soil can be recovered after curing for 24 hours.
