Six quality defects of water supply pipe and treatment methods and PE water supply pipe fittings of the technical requirements of the specific issues

I. Ripples appear on the surface of the pipe. Reason: 1 insufficient cooling, sealing ring size is not appropriate, the formation of vibration phenomenon. Solution: Increase the water absorption of the sizing casing, or increase the distance between the port type and the shaping casing. Check whether the size of the vacuum tank seal is small, reduce, replace or appropriately reduce the vacuum of the vacuum tank, PE homogeneous siphon fittings company to increase the degree of the second vacuum tank vacuum.

Second, the surface of the pitting (mainly the inner wall). Reason: 1 raw materials containing impurities 2 mouth, cleaning and core between the inner wall is not clean 3 part of the temperature. Over the height. This may be the main reason for aging. Solution: 1 check the raw materials 2 cleaning or transition time 3 test temperature sensor

Third, the surface crater. Cause:1 raw materials damp, foam rupture 2 uneven use of water. Solution:1 drying of raw materials 2 adjust the amount of water or replace the low-pressure water pipe

Fourth, the surface bright spots. Ningbo electrofusion fittings sizing bushings insufficient water. Solution: Increase the amount of water in the calibrating jacket and exchange the amount of water in the large calibrating settings Reason: the raw material's water content is too high. Solution: raw material drying treatment 6, the surface of the glass fibre reinforced plastic grating original melting temperature is not appropriate or raw material problems. Solution:Adjust the melting temperature or replace the raw material PE water supply pipe cutting. Cutting degree index is a very important indicator, for the use of pure PE resin and black mother with the production of water supply pipe manufacturers, leading to pipe fittings such indicators of good and bad main reasons are: Taizhou electrofusion pipe fittings the choice of new materials, black mother, in the case of equipment, mixing methods, process control personnel operation, sample preparation and test methods, such as repeated tests to compare and analyze the breaking elongation rate, when the most important factors are analyzed.
