Scope

Main technical content: This document specifies the term definitions, inspected units, inspection agencies, inspection personnel, work procedures, and on-site supervision and inspection requirements for the supervision and inspection of long-distance pipeline construction (hereinafter referred to as "inspection"). This document applies to the supervision and inspection of long-distance pipelines (including GA1 and GA2) designed in accordance with GB 50251 "Design Code for Gas Pipeline Engineering", GB 50253 "Design Code for Oil Pipeline Engineering", and GB/T 34275 "Pressure Pipeline Code - Long-distance Pipelines" during the construction process (including pipeline installation, modification, and major repairs). For the supervision and inspection of process pipelines in oil and gas stations in long-distance pipeline systems, refer to the "Implementation Guidelines for Supervision and Inspection of Pressure Pipelines - Industrial Pipelines". The dividing line between process pipelines in oil and gas stations and line main pipelines is generally the inlet and outlet shut-off valves (isolation valves), or determined by the pipeline user. For modification or major repair processes (except for pipeline construction during emergency repairs) of pipe sections with a total length of more than 100m that are replaced with the same medium once, this document should also be implemented.
