HDPE plastic-wrapped drain pipe is a leading technology product introduced by our company and produced according to national standards. This product has excellent comprehensive performance, excellent cost performance, and can wind water pipes on site according to engineering needs.
The HDPE plastic-wound drain pipe is made of steel-plastic composite profiled strip by spiral wound welding (extrusion welding on the lap joint). The formed pipe has a spiral straight rib structure, and the outer surface of the pipe wall is reinforced by ribs surrounded by spirals at equal intervals. The ribs are made of a common carbon structural steel strip coated with polyethylene, and the steel strip is integrated with the polyethylene by polyethylene coating. The polyethylene pipe wall constitutes a closed fluid passage, and the reinforced steel belt constitutes the ring stiffness of the pipe. The thickness and width of the reinforced steel strip are designed and determined according to different pipe diameters and ring stiffness requirements. Therefore, HDPE plastic steel winding drain pipe has the advantages of excellent cost performance, large diameter, convenient transportation and simple installation. The product perfectly combines all the advantages of ordinary pressureless plastic pipe and strengthens the high strength of steel ribs, which can fully meet the engineering application. Various needs.
Clamp type elastic link:
This type of connection is suitable for Dn ≤ 1200mm pipe. The connecting structure consists of three layers, the innermost thin-walled rubber sleeve, which is tightly sleeved at the tube end to seal the intermediate layer with a certain thickness and a good elasticity of the foam rubber sheet. Filling up. Through the deformation, the tight pressure of the outer stainless steel looper can be uniformly transmitted to the inner sealing rubber plate, thereby eliminating the influence of the unevenness of the pipe end surface, the uneven height of the rib and the ellipticity on the sealing performance; The outer layer is an open stainless steel looper. The fastening bolt on the looper can adjust the tightening force of the looper to the inner layer rubber to ensure the seal, and the stainless steel looper can compensate the ring stiffness of the pipe joint.
