摘要
近年来,由于城市建设规模不断扩大,燃气安全事故频发,特别是城镇埋地次高压和中压钢质燃气管道的安全问题日益严峻。对大量事故案例分析后可知,引起钢质燃气管道事故的主要原因是管体腐蚀和第三方违规施工。成都市气候湿润多雨,土壤富含矿物形成强腐蚀环境,并且地质构造复杂极易形成滑坡泥石流灾害对管道本体造成损坏,因此开展定期检验与风险评估,排除严重事故隐患,保障特种设备安全。
In recent years,due to the continuous expansion of urban construction scale,gas safety accidents had occurred frequently,especially the safety issues of buried sub high and medium pressure steel gas pipelines in cities and towns had become increasingly severe.After analyzing a large number of accident cases,it could be concluded that the main causes of steel gas pipeline accidents are pipe corrosion and third-party illegal construction.The climate of Chengdu was humid and rainy,and the soil was rich in minerals,forming a strong corrosive environment.The geological structure was complex and prone to landslide and debris flow disasters,which could cause damage to the pipeline.Therefore,regular inspections and risk assessments were carried out to eliminate serious accident hazards and ensure the safety of special equipment.
