High density polyethylene structure wall hot winding pipe is a new profiled structure
wall pipe, produced by hot winding forming craft. Material is HDPE, ancillary shoring pipe material; PP or PE. At the begining, this pipe was imported from Germany
carat company, so in domestic, it’s called carat pipe. In China, the acture name is HDPE structure wall hot winding pipe, domestic standard is: GB/T 19472. 2-2004 B
structure wall pipe. This pipe is environmental safety product, light weight, strong b
earing ability, high quality nozzle, long life, corrosion resistance, easy operation, etc. Used for city water supply, drainage, long distance water transmission and farmland irrigation, etc. Diameter: DN300-DN4000, it’s the first choosing for under ground drainage pipe
material:
PE-80 or PE-100
