Problems solved by technology

Although the research on this method has made great progress, there are still many difficulties in solving some specific problems, such as multidimensional measurement of risk acceptance criteria, rationalization of priority ordering of risk acceptance criteria, timely update of risk acceptance criteria, etc.
In addition, although some countries have formulated risk management and analysis guidelines (NORSOK standards), there is no international or national standard specifically for evaluating the acceptability risk of natural gas pipeline accidents, which also brings challenges to the practical application of this method. challenge

[0079] 1. Instance basic data

[0080] The high-pressure gas pipeline in Changzhou is connected from the original reserved port of Changzhou Ganghuamen Station, and buried in the ground after passing through the electric control valve and the bypass ball device. After the pipeline is buried, it is laid westward along the east side of Qingyang Road to the north side of Shanghai-Nanjing Expressway to the planning road of Xiaotang Village, and then it is laid northward and westward along the planning road to Changcheng Road. The north bank is laid westward to Tongjiang Avenue, then laid along the east side of Tongjiang Avenue to S338 Provincial Highway, crosses S338 Provincial Highway in a directional way, turns west, and lays along S338 Provincial Highway to Chunjiang High and Medium Voltage Regulating Station. The design pressure of the pipeline is 4.0MPa, the maximum working pressure is 3.5MPa, the material of the pipeline is L360, the nominal diameter is DN500, the length of ...

Abstract

The invention discloses a city gas pipeline risk rank quantitative assessment method and application thereof. According to the method, a calculation model and a mathematic function for gas pipeline risk rank assessment are determined by selecting tool functions such as a correlation function, a matter element matrix with same characteristics and the like for the gas pipeline risk characteristics, namely a third-party damage and corrosion factor, a design factor and an operation management factor by introducing a matter element and an extension set theory, and defining and calculating a gas pipeline risk rank. In order to simplify a calculation process, a Visual Basic program for the gas pipeline risk rank calculation is programmed on the basis above, so that a manual calculation result is validated and the applicability of the gas pipeline risk rank assessment method based on the matter element and the extension theory set in practice is improved to a great extent; and therefore, the objectivity and the accuracy of the risk rank assessment are embodied and simultaneously the method has a certain practical value. The method is an effective method for enhancing gas pipeline risk management.

Description

technical field [0001] The invention relates to a method for quantitatively assessing the risk level of an urban gas pipeline and its application, in particular to the quantitative calculation of the risk level of the gas pipeline, and belongs to the field of risk control of oil and gas storage and transportation. Background technique [0002] With the acceleration of urban expansion and the aging of the gas pipeline network, vicious accidents such as leakage of urban gas pipelines, fires, explosions, and poisoning have occurred from time to time, and have become the third largest killer after traffic accidents and work-related accidents. [0003] If it is possible to calculate the comprehensive grade of the pipeline according to the use of the urban gas pipeline and various factors, divide the grade, and then adopt hierarchical management, and take targeted technical measures and management measures respectively, to pre-control and reduce possible accidents Disasters, reali...
