Abstract

The invention discloses a town gas polyethylene pipeline failure accident analysis implementation method and system. The town gas polyethylene pipeline failure accident analysis implementation method includes the steps: acquiring the classified information of the pipeline failure consequence for a town gas polyethylene pipeline, and the pipeline accident consequence severity influence factor information, wherein the conveying medium hazard information contained in the pipeline accident consequence severity influence factor information includes a medium danger coefficient, a leakage amount factor and a leakage diffusion factor; according to the classified information of the pipeline failure consequence and the pipeline accident consequence severity influence factor information, acquiring the risk acceptable value, and determining whether the risk acceptable value is within the preset lowest reasonable and practicable area; and when the risk acceptable value is within the lowest reasonable and practicable area, giving a prompt that the risk of accident is acceptable. The town gas polyethylene pipeline failure accident analysis implementation method and system establish a town gas polyethylene pipeline failure consequence evaluation factor system, can establish the town gas polyethylene pipeline risk evaluation factor system and pipeline failure risk grades, and can perform accident analysis.

Description

technical field [0001] The invention relates to the technical field of gas pipelines, in particular to a method and system for implementing failure analysis of urban gas polyethylene pipelines. Background technique [0002] The failure of polyethylene pipes for town gas may lead to leakage of the conveyed medium. By analyzing the hazards of the pipeline leakage medium and its impact on the surrounding objects that may be endangered, the factors affecting the severity of the accident consequences are analyzed. There are three main aspects: the hazards of the transport medium, the distribution of possible hazardous objects, and the factors that affect the change of the accident. The risk acceptance standard refers to the degree to which the public accepts the risk level based on subjective wishes, and it is for a specific event. Risk acceptance criteria are an important link linking risk assessment and risk management. At present, some countries such as the United Kingdom, t...
