Polyethylene gas pipe

Abstract

The invention belongs to the technical field of gas pipelines, and particularly relates to a polyethylene gas pipe which comprises an outer pipe, an inner pipe, an anti-explosion mechanism and a linkage mechanism. The outer pipe is connected to the outer side of the inner pipe in a sleeving mode, a certain cavity is reserved between the outer pipe and the inner pipe, the outer pipe and the inner pipe are made of polyethylene materials, and an anti-explosion mechanism is arranged between the outer pipe and the inner pipe. Fixing rods are uniformly and fixedly connected into the inner wall of the outer pipe; a mounting plate is fixedly connected between every two fixing rods; a first buffer bag is fixedly connected to the inner surface of the middle of the mounting plate. When cavities in the first connecting frame and the second connecting frame are compressed, the second connecting frame can extrude the second buffer bag, so that the non-Newtonian fluid in the second buffer bag and the covering film is solidified instantly, and the outer surface of the inner pipe is solidified instantly; and therefore, when the gas pipe is subjected to impact force, the inner pipe can also form corresponding impact resistance, and the inner pipe is protected.

Description

technical field [0001] The invention belongs to the technical field of gas pipes, in particular to a polyethylene gas pipe. Background technique [0002] PE pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most eye-catching. PE pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. Vinyl. When processing different types of PE pipes, according to the different application conditions, the corresponding resin grades are selected, and ...

Problems solved by technology

When the gas pipe is constructed in advance or the buried depth is shallow, the gas pipe is easy to be cut through during the construction of other supporting pipe networks or road construction in the community, resulting in gas leakage

In order to avoid similar incidents, it is necessary to strengthen monitoring of the constructed gas pipelines or construct them behind other supporting pipeline networks, and ensure sufficient burial depth. At the same time, lay the gas pipelines underground. Since polyethylene gas pipelines have no conductivity, this problem is It brings great inconvenience to the detection and positioning of pipelines
