Description

Wear-resistant PE pipe

Technical Field

The utility model relates to a carry tubular product technical field, concretely relates to wear-resistant PE pipe.

Background

Compared with the traditional cast iron pipe, galvanized steel pipe, cement pipe and other pipelines, the plastic pipe has the advantages of energy conservation, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scaling, simple and convenient construction and maintenance, long service life and the like, and is widely applied to the building industry, municipal administration, industry and agricultural field such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid delivery, agricultural irrigation and the like.

The PE pipe has the advantages of good impact resistance, flexibility, reliable connection and the like, but the surface of the existing PE pipe is poor in wear resistance and easy to wear. And the pipe can be dragged unavoidably in the transportation and installation process, and the pipe is easily abraded. In the subsequent use process, because the thickness of the worn part of the pipe becomes low, the stress of the pipe is uneven, the problem that the pressure bearing capacity of the worn part is insufficient appears, pipe explosion occurs, and potential use risks are caused.
