1 Scope

GB 46767-2025 is the Chinese national standard on identification and management of population intensive high consequence areas for onshore oil and gas transmission pipeline, in the field of petroleum and related technologies. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 31 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2026. Classification: ICS 75.200, CCS E09. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the general requirements, identification and classification, and safety measures for the identification and management of densely populated, high-consequence areas along long-distance onshore oil and gas pipelines. Comprehensive management requirements. This document applies to onshore petroleum (including crude oil, refined petroleum products, and liquefied petroleum gas) and natural gas (including natural gas, coalbed methane, and coal-to-gas). Identification and management of personnel-intensive, high-consequence areas in long-distance natural gas pipelines. This document does not apply to process pipelines within long-distance oil and gas pipelines, urban gas pipelines, oil and gas field gathering and transportation pipelines, or aviation fuel pipelines within airports. Inter-plant and intra-plant oil and gas pipelines of petrochemical enterprises and oil depots.
