Jiangsu Kunshan Huarun Gas PE Pipeline Exploration Project

There are two gas management units, Kunshan Anda Natural Gas Development Co., Ltd. and Kunshan China Resources City Gas Co., Ltd., for the statutory inspection of gas pipelines in this project. The inspection length of Kunshan Anda gas pipeline is 18.155 kilometers, with a total of 60 inspection accounts, with a pipe diameter of DN90-350, and the pipelines are mainly distributed in towns. The inspection length of Kunshan Huarun gas pipeline is 350 kilometers, with a total of 1000 inspection accounts, and the pipe diameter is DN90-350. The pipeline is mainly distributed in towns and villages. Pipeline operation management data, including pipeline operation records, inspection records of various protective measures for pipelines, pipeline inspection records, other construction activities around pipelines, records of the implementation of pipeline hidden danger monitoring measures, pipeline gas safety accident investigation, maintenance reports, pipeline fault handling records, etc. Among them, the operation records include the pressure records and abnormal pressure fluctuation records, flow records, pipeline repair or reconstruction records, pipeline accident or fault handling records, and transportation medium analysis reports.

Gas pipelines unearthed, buried, bifurcated, laid at a lower position, under sewage pipes or other liquid pipelines; Whether the mark stakes, mileage stakes, signboards, signal source wells (tracer lines and warning belts), valve wells, condensate tanks, radiation pipes, etc. of the ground devices of pipelines damaged by the third party (pipeline exposure phenomenon) meet the specifications, and whether the protective belts along the pipelines, including the clear distance from other buildings, are affected by buildings and deep-rooted plants.
