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

The invention discloses an ultra-high molecular weight (UHMW) PE composite plastic water feeding pipe. The UHMW PE composite plastic water feeding pipe is characterized in that the innermost layer of the water pipe is provided with a UHMWPE core pipe. According to the UHMW PE composite plastic water feeding pipe, a polyethylene weather-proof layer can be resistant to erosion by various corrosive media like acid, alkali, salt and organic solvent. A first binding layer and a PE middle binding layer both can combine different materials, and compression strength of the pipe is enhanced. After the UHMWPE core pipe is combined with the first binding layer and a stainless steel mesh layer, the compression strength of the pipe can be further enhanced, the pipe cannot be cracked easily, and the strength of the pipe is even several times of that of a steel pipe under the same load condition. Meanwhile, good shock resistance is achieved, the requirements can be met only through a thin pipe wall in application, and thus the UHMW PE composite plastic water feeding pipe can be widely applied to the field of high-end engineering like medical treatment, sanitation and chemical engineering.

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...
