Generally, urban natural gas pipelines are more than one hundred kilometers long. Although they are regularly patrolled and inspected, sometimes the pipelines need to pass through areas with complex conditions. The leakage of new pneumatic ball valves for natural gas gathering and transmission may cause serious fire accidents. Especially for pipelines near the city, it is particularly important to prevent the leakage of valves. Once the pipeline is put into operation, it is not allowed to stop operation within a few years, and it is not allowed to have a momentary interruption, let alone an overhaul period. Once the pipeline valves connected in series on the pipeline fail, the consequences are unimaginable. Therefore, the wearing parts of pipeline valves are required to have long service life and be safe and reliable.
