High-density polyethylene (HDPE)-reinforced winding corrugated pipe

Abstract

The invention discloses a high-density polyethylene (HDPE)-reinforced winding corrugated pipe. The high-density polyethylene-reinforced winding corrugated pipe comprises an inner-layer pipe body, adhesive resin layers, a steel belt corrugated framework and an outer-layer corrugated pipe body. The steel belt corrugated framework is arranged between the inner-layer pipe body and the outer-layer corrugated pipe body. The steel belt corrugated framework is bonded with the inner-layer pipe body and the outer-layer corrugated pipe body through the adhesive resin layers correspondingly. The inner-layer pipe body and the outer-layer corrugated pipe body are both made of HDPE materials. The steel belt corrugated framework is made of inverted-U-shaped spiral steel belts which are formed by high-quality cold-rolled steel sheets through one-time rolling. The HDPE-reinforced winding corrugated pipe is made of HDPE, and compared with cement pipes and other polyvinyl chloride (PVC) pipes, the HDPE-reinforced winding corrugated pipe is lighter, higher in strength, nontoxic, resistant to corrosion, free of scaling and capable of being recycled. The HDPE-reinforced winding corrugated pipe can be used in the environment with the temperature of minus 60 DEG C without breakage, the anti-cracking capacity during medium delivery is high, the scratch sensitivity is low, the tenacity is high, the adaptability to the differential settlement of a pipe base is high, and no base is needed under the good soil condition.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to an HDPE reinforced winding corrugated pipe. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, the pipes used in home decoration have also experienced the development process of ordinary cast iron pipe → cement pipe → (reinforced concrete pipe, asbestos cement pipe) → ductile iron pipe, galvanized steel pipe → plastic pipe and aluminum-plastic composite pipe . [0003] Spiral corrugated pipe is a kind of pipe material, which can solve a series of problems such as heavy load. The spiral corrugated pi...

AI Technical Summary

Problems solved by technology

Due to the lack of high-quality cold-rolled steel plate skeleton, the spiral corrugated pipe produced in the past has poor compressive capacity, and the flow is affected by compression deformation. It is easy to corrode and has a short service life, which is difficult to meet the needs of special environments.
