Polyethylene of raised temperature resistance, abbreviated as PE-RT. As a new type of plastic pipe, PE-RT pipe has become the main force in building hot water system and floor heating system, especially in floor heating pipe system, with its long-term hydrostatic strength, temperature resistance, pr......

With the enhancement of people's awareness of environmental protection, the requirements for building water supply and drainage are higher and higher, and various new structural PVC-U pipes came into being. Its functions and characteristics are different.

The PE extrusion production line overcomes the friction generated by the pipe passing through the sizing sleeve and the sealing gasket of each cooling water tank through forced traction. The stability of traction speed determines the wall thickness uniformity of the pipe. PE pipe haul-off adopts cat......

Vacuum setting device is an important part in PE pipe production line. The design of vacuum setting device directly affects the stability of production and the quality of internal and external surfaces of pipes. An excellent vacuum setting device should provide strong cooling capacity; stable vacuum......

In pipe extrusion production, the quality of extrusion die also plays a very important role in product quality. For processing polyethylene materials, an optimized pipe extrusion die should meet the following requirements:

The setting device in the die is the main component in the PE pipe extrusion system. The molten material is cooled on the inner surface of the sizing sleeve to form a solid surface layer to ensure the accurate outer diameter of the pipe. It also ensures the stability and normal traction extrusion of......
