Polyurethane Spraying Prefabricated Insulated Steel Pipe Automatic Production Line
Description
HDPE Jacket Pipe Extrusion Line is high-efficient with high speed and energy saving for producing HDPE thin wall pipe, which is used as protective cover of PU foam thermal Pre-insulated Pipe according to international standard.
The HDPE jacket pipe is produced by vacuum calibrating method with smooth internal and external wall, long service life, good anti-corrosion insulation and mechanical performance.

Die-head is mainly composed of mandril, neck mold, spiral body, cover, die-head body, bolts, and heating rings. The inside surface touching with plastic materials is polished and chrome plated to ensure plastic materials flow smoothly and to ensure no rusting. The uniformity of pipe wall thickness can be adjusted by bolts. The copper calibrating sleeve fixed in die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diameter.
