At present, the main causes of gas pipeline accidents are as follows:First, the corrosion and aging of gas installations and gas pipeline networks. Gas installations and combustionThe gas pipelines have corresponding operating time limits, and the pipelines operate under the background of over-limitThe transfer will cause leakage due to aging and damage to the pipeline, which will lead to accidents. becauseThe degree of acid and alkali in the soil near the pipeline is not the same.Corrosion is also different. Stronger corrosive soil will cause pipelines to recover.Without exceeding the limit, it is very easy to cause perforation of the pipe wall and cause leakage. Second, violationRegulations occupy gas pipelines, are located above natural gas installations, orConstruction within a safe distance.
