Description

Protective multilayer explosion-proof PE pipe Technical Field The invention relates to the technical field of PE pipes, in particular to a conformal multilayer explosion-proof PE pipe. Background In the field of pipeline transportation, the PE pipe is widely applied to various industries such as water supply, fuel gas, chemical industry and the like by virtue of the advantages of light weight, corrosion resistance, convenience in installation and the like. However, conventional PE tubing suffers from a number of significant drawbacks in dealing with abnormally elevated pressure within the tubing. Conventional PE tubing lacks an effective pressure relief and self-protection mechanism when the pressure in the tubing suddenly increases for various reasons (e.g., equipment failure, operational errors, abrupt temperature changes, etc.). Excessive pressure can create significant stresses on the tubing, causing the tubing to expand and deform, and even fracture. Once the pipeline is broken, not only leakage of the conveying medium is caused, resources are wasted, but also pollution to the surrounding environment is possible. For example, in a fuel gas conveying pipeline, serious safety accidents such as fire and explosion can be caused by fuel gas leakage, life and property safety of people is threatened, and in a chemical raw material conveying pipeline, ecological environments such as soil, water sources and the like can be damaged for a long time and difficult to repair due to leakage of harmful chemical substances. In addition, when the pressure of the traditional PE pipe is abnormal, the traditional PE pipe is difficult to quickly and effectively prevent further expansion of leakage, and due to the lack of an active plugging mechanism, the leakage can continue until a worker finds and takes maintenance measures, so that the difficulty and the cost of maintenance are increased, the production stopping time is prolonged, and huge economic loss is brought to enterprises.
