Problems solved by technology

[0003] However, such tubes with a single-layer film structure cannot withstand the mechanical stress imposed by high-pressure water flow or air flow
In addition, such single-layer tubes are bulky and difficult to maneuver
Also, the presence of a single layer makes the tube vulnerable to damage from strong corrosive chemicals such as ozone and chlorinated derivatives
Additionally, monolayer films lack mechanical strength, reducing the overall efficiency of the tube

Abstract

A multi-layer pipe 100 for conveying fluids comprises at least three concentric layers, and the three-layer concentric layer pipe includes: an upper layer 102 , a middle layer 104 and a lower layer 106 . The upper layer 102 and the lower layer 106 are made of linear low density polyethylene and low density polyethylene, while the middle layer 104 is made of high density polyethylene. The present invention discloses that the middle layer is woven from fabric in a warp and weft pattern 108, which is then applied to the lower and upper layers laminated by a laminator.

Description

technical field [0001] The present invention relates to a multilayer pipe for transporting liquids, gases and the like, and more particularly to a multilayer pipe comprising structurally separate layers of polyethylene. Background technique [0002] It is generally accepted that tubes are used to transport various substances, such as liquids, gases or the like, around. Pipes traditionally made of steel or cast iron are being replaced by plastic pipes. These tubes are made from a single layer of film. As technology develops, tubes are made of various materials with better mechanical properties. Such tubes can be connected as required. [0003] However, such tubes with a single-layer film structure cannot withstand the mechanical stress imposed by high-pressure water flow or air flow. Furthermore, such single-layer tubes are bulky and difficult to manipulate. Also, the presence of a single layer makes the tube vulnerable to damage from highly corrosive chemicals such as o...
