a pe tube

Abstract

The invention belongs to the technical field of pipes and particularly relates to a PE (polyethylene) pipe. The PE pipe comprises a pipe body and a rebound mechanism; the rebound mechanism is arranged in the pipe body; the rebound mechanism comprises extruding cavities, elastic layers, springs and supporting rods; the extruding cavities are arranged in the wall of the pipe body uniformly; the elastic layer is arranged on the inner side of each extruding cavity; the elastic layer and the inner wall of the pipe body are connected integrally; each elastic layer has a certain degree of flexibility; the supporting rods are fixedly arranged in the elastic layers horizontally and uniformly; and the supporting rods are connected through the springs. The PE pipe is mainly used for solving the problems in the prior art that a PE water discharging pipe is blocked because the PE water discharging pipe is liable to enable stone to enter the pipe when a filtering net is not mounted and the PE water discharging pipe is used in a mine as well as the inner wall of the pipe is scratched continuously and the durable degree of the PE water discharging pipe is greatly reduced because the stone is liable to generate relative friction with the inner wall of the PE water discharging pipe when the stone is conveyed in water and in the pipe.

Description

technical field [0001] The invention belongs to the technical field of pipes, in particular to a PE pipe. Background technique [0002] PE is polyethylene plastic, the most basic kind of plastic, plastic bags, plastic wrap, etc. are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. According to the wall thickness, it is divided into SDR11 and SDR17.6 series. The former is suitable for transporting gaseous artificial gas, natural gas and liquefied petroleum gas, while the latter is mainly used for transporting natural gas. Compared with steel pipes, the construction process is simple and has a certain degree of flexibility. What's more, it does not need to be used for anti-corrosion treatment, w...

AI Technical Summary

Problems solved by technology

The invention is mainly used to solve the problem that when the PE drainage pipe in the prior art is used in mines without installing a filter net, it is easy to cause stones to enter the pipe, thereby causing the PE drainage pipe to be blocked. Relative friction occurs on the inner wall of the pipe, which causes the inner wall of the pipe to be scratched continuously, resulting in a problem that the durability of the PE drainage pipe is greatly reduced
