High-strength corrosion-resistant polyethylene composite pipe

Abstract

The invention discloses a high-strength corrosion-resistant polyethylene composite pipe. The high-strength corrosion-resistant polyethylene composite pipe comprises an inner-layer pipe, a middle reinforcing layer, a plurality of reinforcing rings and an outer-layer pipe, wherein the inner-layer pipe is made of a polyethylene material; the middle reinforcing layer is made of a high-strength aluminum alloy and comprises a plurality of reinforcing strips attached to the outer surface of the inner-layer pipe; the reinforcing rings are arranged on the outer surface of the middle reinforcing layer at intervals and are fixed to the reinforcing strips of the middle reinforcing layer in a welded mode; the reinforcing strips are made of a high-strength aluminum alloy; and the outer-layer pipe is made of the polyethylene material and covers the outer surfaces of the middle reinforcing layer, the inner-layer pipe and the reinforcing rings. The middle reinforcing rings and the reinforcing strips are wrapped through the inner-layer pipe and the outer-layer pipe, the overall strength of the pipe can be enhanced through the middle reinforcing rings and the reinforcing strips, and therefore the polyethylene composite pipe has the advantages of high strength and corrosion resistance and can be suitable for places with the requirements for strength and corrosion resistance.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a high-strength, corrosion-resistant polyethylene composite pipe. Background technique [0002] Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. Existing pipes can be mainly divided into metal pipes and plastic pipes according to their materials. Although metal pipes have relatively high strength, they are easily corroded. Although plastic pipes (such as polyethylene pipes, etc.) are relatively corrosion-resistant, they have strength. Low problem, so the advantages of high strength and corrosion resistance cannot be achieved. Contents of the invention [0003] In order to overcome the pipes in the prior art that cannot meet the requirements of high strength and corrosion resistance at the same time, the problem to be solved in the present invention is to propose a h...
