At present, pipeline transportation becomes a main transportation mode for dangerous substances such as petroleum, natural gas and the like and fluid materials, and particularly after national energy strategy adjustment and successful operation of west-east gas transportation engineering, the pipeline transportation mode is used on a large scale. At present, the pipeline transportation industry plays an important role for the rapid development of economy. With the large-scale use of pipeline transportation, the safety of pipeline transportation is more and more emphasized by people.
