Background

The polyethylene double-wall corrugated pipe is a novel pipe with smooth inner wall and annular corrugated structure, which is produced by using high-density polyethylene as a main raw material and adopting three processes of pipe forming, cutting and flaring. The pipe is characterized by being firm and durable: the material has strong chemical stability, aging resistance and environmental stress cracking resistance. The ring rigidity is greatly enhanced due to the hollow and annular corrugated structure; the cost is low: compared with concrete pipes and cast iron pipes, the pipe is low in purchase price and simple in construction and installation, and construction cost and labor expenditure are reduced to a great extent; the flux is large: the smooth inner wall reduces the friction coefficient, increases the flux in unit time and enhances the anti-silting and anti-blocking capability.

The pipe is used for drainage and ventilation of mines and buildings; outside network pollution discharge of municipal works and residential districts; irrigation, water delivery and drainage of irrigation and water conservancy; the drainage and the delivery of sewage treatment plants and garbage disposal plants; chemical ventilation and fluid transportation of chemical industry and mines; integrally processing the pipeline inspection well; pre-buried pipelines of the expressway; protection of high voltage cables, post and telecommunications cables, etc.

When the corrugated pipe is used, particularly when the corrugated pipe is buried underground for use, the wave crest of the corrugated pipe is easy to be pressed to generate large deformation due to external pressure, so that the corrugated pipe is damaged, and the service life of the corrugated pipe is shortened.
