PE (polyethylene) material is widely used in the field of water supply pipe manufacturing because of its high strength, corrosion resistance, non-toxic and other characteristics. Because it does not rust, it is an ideal alternative to ordinary iron pipes. PE pipe surface is much smoother than cast iron pipe, and its small friction coefficient and fluid resistance also can reduce the fluid transport energy consumption of more than 5%; Besides,Good comprehensive energy saving effect can reduce manufacturing energy consumption by 75%; Easy to transport and install. It is widely used for building water supply, building drainage, buried drainage pipe, building heating, pipe, electrical and telecommunications protection casing, industrial pipe, agricultural pipe and so on. It is mainly used in urban water supply, urban gas supply and farmland irrigation.


We are familiar with the uses and characteristics of PE tubes, but only a few people know how they are made. Today, I will explain the production process of PE pipe fittings for you.

PE pipe production technology for extrusion molding process, the first in the feed hopper of polyethylene (PE) raw material by gravity into the extruder, the extruding machine cylinder heating extrusion blending, Canon from after sufficient plasticizing extruder die extrusion, enter the calibrating bench, after finalize the design of the PE pipe by tractors, through determination of fixed length, cut off by cutting machine, and pipe storage after inspection. The corresponding pipe fittings are produced by injection molding.

PE pipe production process: PE raw material → vacuum suction feeding → hopper storage → feeding → extrusion forming → cooling forming → traction → cutting → inspection → storage pipe production process: PE raw material → conveying feeding → hopper storage → feeding → heating and melting → extrusion injection molding → cooling forming → mold opening → inspection → storage.
