[0002] Oil and gas pipelines are important facilities for transporting oil, natural gas and their products. They are divided into oil pipelines and gas pipelines. Depending on the different products transported, oil pipelines can be divided into crude oil pipelines and refined oil pipelines. Oil and natural gas flow along the pipelines through pressure differences, flowing from the extraction end to the production end and the application end.
[0003] If an oil and gas pipeline leaks, it will cause the following hazards: Oil and gas are flammable and explosive substances. Once leaked, they are prone to fire or explosion accidents when encountering fire sources such as open flames or static electricity; oil and gas leakage will pollute the soil, water sources and air, and have long-term impacts on the ecological environment. Therefore, oil and gas pipelines need to be leaked in actual use.
