In China, natural gas, natural gas pipeline is the main mode of transport by land transport, as the pipeline prone to accidents, often accompanied by an explosion and fire. Accident risk and consequences of the seriousness of the relatively large masses of the people and the environment a significant impact. As long distance gas pipeline system complexity risk, a detailed analysis of the various long distance gas pipeline elements and each part of the project risk analysis. The project risks are mainly corrosion, earthquake fault zone, floods, mine subsidence, landslides, water gullies, corrosion, corrosion potential and the potential buried, gas explosions and combustion, third-party damage to pipeline pressure testing, construction defects. Of the Natural Gas Pipeline, natural gas sub-regional case study projects, and noted that each section of the main risks.
