Abstract

The invention discloses an ultrahigh molecular weight PP composite plastic water pipe. The ultrahigh molecular weight PP composite plastic water pipe is characterized in that an innermost layer of the water pipe is an UHMWPP core pipe; the UHMWPP core pipe is wrapped by a first combination layer; the first combination layer is wrapped by a stainless steel wire net layer; the stainless steel wire net layer is wrapped by a PE middle combination layer; and the PE middle combination layer is wrapped by a HDPE weather resisting layer. The ultrahigh molecular weight PP composite plastic water pipe has such characteristics as high performances, high adaptability, high combination strength, bacteria resistance, no poison, no irritation, corrosion resistance and difficult rusting. A polyethylene weather resisting layer can resist erosion of such various corrosive mediums as acid, alkali, salt and organic solvent. The first combination layer and the PE middle combination layer both can be combined with different materials, and improve the pressure resisting strength of the pipe; the UHMWPP core pipe is high in strength, free of poison and environment-friendly; after the UHMWPP core pipe is combined with the stainless steel net layer by the first combination layer, the pressure resisting strength of the pipe can be further improved, and the pipe is not easy to break; under the condition of the same load, the pipe is higher than a steel pipe in strength by several times; and meanwhile, the pipe is excellent in impact resistance.

Description

technical field [0001] The invention relates to a pipe, in particular to an ultra-high molecular weight PP composite plastic water pipe. Background technique [0002] Water supply and drainage pipes are widely used in water supply and drainage fields such as roads, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields, etc., as well as underground irrigation and drainage systems for agriculture and horticulture. Because traditional metal water supply and drainage pipes are buried underground for a long time, they are particularly prone to corrosion and rust, and even cause serious problems such as perforation and blockage. At present, plastic water pipes are developing rapidly, and most of them are dominated by polyethylene (PE) and polyvinyl chloride (PVC) pipes. Although the problem of metal pipes being easy to corrode and rust has been solved to a certain extent, the common problem is poor impact resistance. , Low compressive strength a...
