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.
