Introduction
This standard is to meet the relevant national legislation, regulations on buried steel pipeline risk assessment requirements and the proposed project needs to be buried
The method of steel pipeline risk assessment, mainly for use in risk assessment buried steel pipeline, but also for buried steel pipeline feasibility
Demonstration phase, the risk of the design review stage and completion stage of the assessment of delivery is provided a method.
This standard is based on the basic principles of risk assessment for a comprehensive assessment of the likelihood and consequences of the accident from the accident two underground steel
Pipeline quality level of risk in its actual use conditions and the environment, is suitable to the actual semi-quantitative risk assessment project.
Buried steel pipeline risk assessment methods
1 Scope
This standard specifies the terms, definitions and symbols buried steel pipeline risk assessment, general principles, basic risk assessment workflow, duct sections
Division, evaluate the possibility of failure, failure consequence evaluation, risk value calculation, risk classification, risk reduction measures and risk re-evaluation of the recommendations.
This standard applies to transport crude oil, refined oil Pipeline, corrosive liquid, gas medium, gathering and transportation pipelines, natural gas transportation, artificial
Gas, liquefied petroleum gas pipeline public media, transport corrosive liquid media industry pipeline buried steel pipeline for its underground section
Points across the exposed portion and the tube portion in the feasibility study stage, the design review stage, the final acceptance stage, the risks with stage four stages
Evaluation.
This standard does not apply to non-steel long-distance pipeline, gathering and transportation pipelines, utility pipeline, transporting corrosive liquid medium risk assessment of industrial pipes
Assessment, does not apply to long-distance pipelines, field gathering pipeline stations, utility pipes, conveying corrosive liquid medium of industrial pipes of various devices,
Risk assessment of the device itself.
