HDPE Large Caliber winding pollution discharge pipe machine
HDPE Large Caliber winding pollution discharge pipe is a new type of plastic drain pipe in the 90s. At present widely used as an alternative to concrete pipe in drainage project. At home initial development of plastic pipes is UPVC corrugated pipe, as large caliber pollution discharge pipe, UPVC corrugated pipe equipment investment is big, compressive strength is not enough, so winding pipes appears. The earliest winding pipes is lap joint winding, although on the spot can be wound for forming, but the interface strength is poor. Recently the developing material is double wall winding pipe, which uses the melt filling joint.
