Method for producing plastic pipe fitting with insert made from polyphenylene sulfide alloy material

Abstract

The invention relates to a method for making a plastic pipe with an insert made from a PPS alloy material. Materials such as PPS, nylon, etc. are treated with steps of blending, extrusion, strip stretching, cooling, pelletizing, homogenization, injection molding, etc. so as to obtain the plastic pipe with the insert made from the PPS alloy material. The making method of the invention has simple and easy technique; the alloy material has the advantages of small specific weight, good heat and corrosion resistance as well as good dimensional stability; in addition, the obtained pipe has good sealing, high notched impact strength, etc. The plastic pipe provided by the invention has wide range of application and can be applicable to water supply and drainage systems and drinking water pipe systems, gas transmission systems and industrial pipe systems, heating systems and agricultural pipe systems.

Description

technical field

[0001] The invention relates to the field of building materials, in particular to a method for making plastic pipe fittings from polyphenylene sulfide composite materials. Background technique

[0002] Plastic pipes are mainly used in the construction industry for water supply and drainage and water pipe systems, gas transmission and industrial pipe systems, heating systems and agricultural pipe systems. Plastic types for making plastic pipes and fittings include HDPE, PP, PPB, PPR, PPH, PVC, ABS, and PA, etc. Plastic pipe fittings are also called plastic fittings, which include joints, elbows, tees and crosses, etc. The inserts in the current plastic pipe fittings are basically made of metal copper, that is, the metal copper rods are used as materials and made through five machining processes such as blanking, rough turning, fine turning, turning and milling. The connection between fittings and plastic pipe fittings is integrated by one-time injection mold...
