Anti-corrosion device for indoor gas pipe

Abstract

The invention discloses an anti-corrosion device for an indoor gas pipe. The anti-corrosion device comprises the gas pipe, a casing pipe and tightening hoops, wherein the casing pipe is arranged on the outer wall of the gas pipe, and the tightening hoops are arranged at the two ends of the casing pipe. The casing pipe is of a round structure and divided into a left casing pipe body and a right casing pipe body. A protective belt layer is arranged outside the casing pipe. The fastening hoops at the two ends of the casing pipe are fastened through screws. The outer walls of the fastening hoops are fixed through tying belts. A waterproof cover is arranged on each fastening hoop. An anti-corrosion layer is arranged between the casing pipe and the gas pipe. The anti-corrosion casing pipe is arranged on the rear portion of the anti-corrosion device for the indoor gas pipe, and it is guaranteed that a uniform cavity is formed around the pipe; the mode that pouring is conducted from bottom to top is adopted, the formed anti-corrosion layer is uniform and compact, and the situation that anti-corrosion materials are excessive at one side and missing in coating at the other side is avoided; in addition, assembling can be completed rapidly; the anti-corrosion casing pipe which is arranged on the rear portion can be constructed with rust, and the anti-corrosion device is more suitable for the circumstance in which rust cannot be removed, such as repair of a through-wall vertical pipe; and by means of unique design of the casing pipe arranged on the rear portion, construction efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of door-to-door gas delivery pipeline maintenance, in particular to an anticorrosion device for indoor gas pipelines. Background technique [0002] At present, the gas industry generally adopts the pipe replacement method to deal with the corroded gas pipe in the gas transmission pipeline. This method of operation must be carried out after stopping the gas, and then suppressing the pressure after changing the pipes, and then ventilating and igniting after passing the test. This operation method directly affects the gas consumption of the user. A few years later, the newly replaced new pipe appeared corroded and perforated again, which caused the hidden danger of deflagration in the gas system. Especially the gas pipelines passing through the floors are more susceptible to corrosion. Because this section is located between floors, and the general gas pipes are in the kitchen, they are installed with water pipes...

AI Technical Summary

Problems solved by technology

Because this section is between the floors, and the general gas pipelines are in the kitchen, they are set together with the water pipes and drain pipes, which will cause damage to the anti-corrosion layer, resulting in corrosion or breakage of the new pipes after only 8-10 years of operation.

For a long time, the method of pipe replacement is still used to solve the problem of pipeline corrosion, so the operation must be stopped, which directly affects the daily life of users
