Double-wall corrugated high density polyethylene pipe is made of high-density polyethylene is extruded simultaneously through a corrugated outer wall and an inner wall of the first layer of smooth extruded solution knot. In addition to its high resistance to corrosion ordinary plastic pipe has good, high insulation, wall smooth, flow resistance characteristics of small outside, due to the use of a special hollow annular structure, it also has excellent ring stiffness and good strength and toughness , light weight, high impact resistance, not damaged and so on. Double-wall corrugated pipe is widely used in municipal sewage drainage, irrigation, mine ventilation, chemicals, telecommunications cable sheathing and other fields. Practice has proved that meet the same strength and stiffness requirements under corrugated PVC pipe production line, double-wall corrugated pipe than ordinary plastic pipe material savings of 30% -50% corrugated pipe production line, easy to install and transport, reduce the labor intensity of construction personnel, but also reduces the total investment of the project, concrete pipe, ideal replacement of cast iron pipes is PVC single wall corrugated pipe equipment Products: I produced the PE, PP, PVC, PA single wall corrugated pipe production line pipe production line manufacturers, by Gear module, a template string water cooling, air cooling products to enable the production of corrugated pipe forming speed, a corrugated shape uniform, consistent joints, outer wall smooth. This product is excellent, the production speed, beautiful appearance. To produce products of high temperature, corrosion resistance, wear resistance, high strength, good flexibility and so on. Features: 1, bellows forming machine as the closed structure, and provide vacuum forming; 2, the special structure of the screw, mold design reasonable corrugated pipe production line in Qingdao, convenient and reliable to replace the mold; 3, through the corresponding mold forming a smooth inside and outside corrugated uniform bellows products; 4, high production speed, fast cooling. PE corrugated pipe production line, day Nobuyasu (online consultation), corrugated pipe production line Qingdao day letter provided by Thai Plastic Machinery Co., Qingdao day letter Thai Plastic Machinery Co., Ltd.
