Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a gas pipe joint assembly. Background Art

[0002] In modern industrial and civil construction, gas pipe fittings play a key role in connecting various parts of the gas pipeline system. These components must not only ensure the tightness of gas transmission and prevent any possible leakage, but also be able to withstand the working pressure inside the system to ensure the safe transportation of gas. At the same time, they must adapt to various physical conditions in the installation environment, including temperature changes, humidity levels, and the influence of surrounding media.

[0003] The technical problems faced by traditional gas pipe joint assemblies mainly include loosening caused by electromagnetic interference, mechanical vibration, and corrosion after long-term use. First, in a complex electromagnetic environment, the joint may be affected by electromagnetic interference, generating eddy currents that cause heat accumulation and damage its performance and life. Secondly, continuous mechanical vibration will weaken the friction between the joint threads, causing the connection to gradually loosen, increasing the risk of leakage and requiring frequent maintenance. Finally, long-term exposure to moisture and oxygen will cause corrosion of metal joints, destroy the sealing and reduce the mechanical strength, posing a safety hazard. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned traditional technology, the purpose of the utility model is to provide a protective gas pipe joint assembly.
