Scope

Main technical content: This document specifies the terms and definitions, basic process, main contents, and basic requirements involved in the risk investigation and assessment of the quality of circumferential welds in buried steel pipes. The risk assessment covered in this document comprehensively evaluates the risk level of circumferential welds in buried steel pipes under their actual operating conditions and environments from the perspectives of the possibility of accidents and the consequences of accidents. It is a semi-quantitative risk assessment method suitable for engineering practice. This document is applicable to the quality risk investigation, excavation inspection, and risk assessment of in-service buried steel pipe circumferential welds, but not to non-steel pipes, on-site process pipes, or other overhead pipes.
