PPR, PP, PE Single Layer or Multi-layer Pipe Co-extrusion Production Line

1. PP-R, PP, PE single-layer or multi-layer water supply pipe features:

In current construction and installation projects, PE, PP, PPR pipes (pieces) are mostly used for heating and water supply.?Its advantages are convenient and quick installation, economical, environmentally friendly, light weight, hygienic and non-toxic, good heat resistance, corrosion resistance, good thermal insulation performance, long life and so on.

2. About the production line:

The extruder is controlled by PLC or temperature control instrument, the temperature control is accurate, and the plasticizing quality is effectively guaranteed; the special screw design ensures high efficiency and high output; the helical gear design with high hardness and low noise brings reliable and stable extrusion performance and long service life.

The diverter of the pipe die adopts spiral distribution type or blue type diverter.?The large flow space ensures sufficient residence time of the melt; the internal stress in the pipe is small, and the inner and outer surfaces are smooth; the die design has high flexibility and is suitable for co-extrusion of all polyolefin materials (two-layer, three-layer, four-layer) forming.?The multi-layer pipe is a newly developed equipment of our company in recent years, such as the three-layer pipe, the inner and outer layers are pure raw materials, and the middle layer is recycled plastic and glass fiber material, which effectively improves the toughness and strength of the pipe and reduces the product production cost.
