依据TSG D7003-2010《压力管道定期检验规则——长输(油气)管道》对长输天然气管道依法开展全面检验是及时发现缺陷和隐患的关键手段。根据规范要求,对受检管道资料审查分析完成后,应当按照有关标准进行风险评估。本文主要依据GB/T 27512,采用半定量法,对新疆地区某长输管道进行了全面检验工作前的风险评估,分析了风险值,得到了相应的风险等级,为后续选择全面检验方法提供了依据。
According to TSG D7003-2010 Rules for Periodic Inspection of Pressure Pipes - Long-distance Pipelines for Oil and Gas (LNG), the thorough examination and verification according to law of long-distance natural gas pipelines is the key means for timely detection of defects and risks. According to the requirements of the code, after the examination and analysis of the examined pipeline data is completed, the risk assessment shall be carried out in accordance with relevant standards. This paper mainly based on GB / T 27512, using semi-quantitative method, a long-distance pipeline in Xinjiang conducted a comprehensive inspection before the risk assessment, analysis of the value of the risk, the corresponding level of risk has been provided for the subsequent selection of comprehensive testing methods provided in accordance with.
