Embodiment 1

[0014] Embodiment 1: as figure 1 , as shown in 2, the innermost layer of the ultra-high molecular weight PE composite plastic water supply pipe is a UHMWPE core tube 5, the UHMWPE core tube is wrapped with a first bonding layer 6, and the outer layer 6 of the first bonding layer is wrapped with a stainless steel wire mesh layer 7, and the stainless steel mesh Layer 7 is wrapped with PE intermediate bonding layer 8, and the outer wall of PE intermediate bonding layer 8 is wrapped with HDPE weather-resistant layer 9; An embedded metal wire 81 is also provided between the PE intermediate bonding layer and the HDPE weather-resistant layer. The embedded metal wire 81 and the stainless steel wire mesh layer 7 form a data transmission loop. If the sensor is installed in the pipeline, the embedded metal wire and the stainless steel mesh layer can be directly connected to the sensor to form a data transmission channel, which greatly reduces the wiring of the sensor. trouble.

Abstract

An ultrahigh molecular weight polyethylene (PE) composite plastic water supply pipe is characterized in that an ultrahigh molecular weight polyethylene (UHMWPE) core pipe is arranged on the innermost layer of the water supply pipe; the UHMWPE core pipe is wrapped with a first bonding layer, the first bonding layer is wrapped with a stainless steel screen layer, and the stainless steel screen layer is wrapped with a PE intermediate bonding layer. The ultrahigh molecular weight PE composite plastic water supply pipe has the characteristics of being high in performance, high in applicability, good in antibacterial performance, high in bonding strength, nontoxic, free of stimulation, resistant to corrosion, not prone to rusting and the like. Both the first bonding layer and the PE intermediate bonding layer can be combined with different materials, and the compression strength of the pipeline is improved; after the UHMWPE core pipe is combined with the first binding layer and the stainless steel screen layer, the compression strength of the pipeline can be further improved; under the same load condition, the compression strength of the pipeline is even several times higher than that of a steel pipe, and meanwhile, the pipeline has good shock resistance; when the ultrahigh molecular weight PE composite plastic water supply pipe is applied, requirements can be met only through a thin pipe wall so that the ultrahigh molecular weight PE composite plastic water supply pipe can be widely applied to the high-end engineering fields such as the medical field, the health field and the chemical field.

Description

technical field [0001] The invention relates to a pipe, in particular to an ultra-high molecular weight PE composite plastic water supply 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 str...
