Scope

Scope: This document specifies the technical content of integrity management for urban gas pipelines, including system construction and audit, data collection and management, hazard detection and key area identification, risk assessment, inspection and monitoring, risk mitigation and control, conversion, decommissioning, and effectiveness evaluation, as well as intelligent management. This document applies to the following urban gas pipelines: a) Gas pipelines: Public gas pipelines and their ancillary facilities between gas stations (including gate stations, storage and distribution stations, and various gas source plants) and user riser valves, or between stations (excluding pressure regulating stations). b) Ancillary facilities include line valve wells (rooms), pressure regulating stations (including pressure regulating boxes), condensate tanks, cathodic protection devices, etc. This document does not apply to the following urban gas pipelines: a) Long-distance gas pipelines designed in accordance with GB 50251 *Design Code for Gas Pipeline Engineering* and GB/T 34275 *Pressure Pipeline Code – Long-Distance Pipelines* prior to urban gas gate stations; b) Gas pipelines within stations (excluding pressure regulating stations) in the gas system; c) Internal gas pipelines of industrial users (divided by plant boundaries or pressure regulating boxes); d) Intake pipes, risers, and horizontal main pipes of commercial or residential users (defined by the connection point between outdoor gas distribution branch pipes and intake pipes). Note: The integrity management of intake pipes owned by pipeline gas operating enterprises or entrusted to them for operation and management may be referenced for implementation. **Main Technical Content**: This document specifies the technical content of integrity management for urban gas pipelines, including system construction and audit, data collection and management, hazard detection and key area identification, risk
