Problems solved by technology

[0005] However, the above three methods are all remedial measures after natural gas leakage occurs, and all three remedial measures have certain limitations, such as directly tightening the flange, the success rate of dealing with flange leakage is relatively low; replacing the sealing assembly requires Pipeline stoppage affects life and production; making flange fixtures requires a lot of extra parts, and the fixtures are prone to failure

Abstract

The invention relates to a natural gas pipeline with a flange sealing joint and an installation method thereof, which can effectively prevent flange leakage of the natural gas transmission pipeline. The flange sealing joint includes a male joint and a female joint. The radial end surface of the male joint is provided with a protrusion outside, and the end of the female joint is provided with a recess that can accommodate the protrusion of the male joint. Both the protrusion and the recess are circumferential Set a circle in the direction, and set an internal seal at the connection between the male joint and the female joint. The internal seal is set in a circumferential circle. The outer surface of the internal seal is provided with an adhesive, which can be bonded to the inner wall of the natural gas pipeline. , to realize the sealing of the butt joint; it can effectively solve the technical problem of leakage of the flange of the natural gas pipeline, the sealing effect is good, and the cost is low, and the installation and operation are simple and convenient.

Description

technical field [0001] The invention relates to a natural gas pipeline, in particular to a natural gas pipeline with a flange sealing joint and an installation method thereof. Background technique [0002] Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of natural gas pipelines to transport natural gas is a way to transport large quantities of natural gas on land. Natural gas pipelines account for about half of the world's total pipeline length. [0003] The gas transmission pipeline system is a continuous closed transmission system. From transmission, storage to user use, natural gas is under pressure. When an accident occurs, it is very harmful and affects a wide range. Once the pipeline leaks, it will cause waste of natural gas. If the discharged natural gas enco...
