GB/T 46543-2025 Integrity management of non-metallic pipeline for oil and gas transmission
Basic Information
Scope
This document specifies the general requirements for the integrity management of non-metallic pipelines used for oil and gas transmission, and establishes integrity management during the construction period, integrity management during the operation period, integrity management during the decommissioning period, failure management, as well as related content of record and document management, communication and change management, and training and skills. This document is applicable to the integrity management of non-metallic pipelines used for oil and gas transmission (such as fiberglass pipelines, flexible composite high-pressure transmission pipes, thermoplastic plastic-lined fiberglass composite pipes, steel-framed reinforced polyethylene composite pipes, and polyethylene pipes), and also applies to the integrity management of non-metallic pipelines used for injection and produced water transportation in oil and gas field surface systems.
