PE Large Aperture Insulation Pipe Production Line

plastic machinery PE large aperture insulation pipe production line is a new product developed by our company on the base of absorbing and digesting advanced technology of late 1990s from the world. The electric components of main machine adopt frequency conversion technology. The production is characterized by high output, good plasticizationand quality.The devices of the production line are mainly used for producing HDPE casing pipes for the protection of heating power pipeline, i.e., inner layer is steel pipe,outer layer is HDPE pipe, the part between steel pipe and HDPE pipe is poured into rigid foamed polyurethane, which is widely used in post and telecommunication,construction, chemical and agriculture industry. As it is characterized by heatpreservation, heat insulation, sound insulation and high mechanical strength,it has good graces in chemical and construction
