Main technical content: This document specifies the terms and definitions of the non-fire (pressure-bearing) emergency repair process for oil and gas gathering and transportation metal pipelines, the scope of non-fire (pressure-bearing) emergency repair operations, general requirements for clamping devices, pre-construction preparations, non-fire pressure-bearing leak repair processes, non-fire pressure-bearing perforation processes, and requirements for non-fire connection processes. This document is applicable to emergency repair and modification/expansion projects of oil and gas gathering and transportation metal pipelines using injection groove sealing clamping devices (hereinafter referred to as "clamping devices") for non-fire (pressure-bearing) leak repair, perforation, and connection. It applies to the construction of onshore oil field gathering and transportation steel pipelines with a design pressure of no more than 35 MPa and a design temperature of -20°C to 360°C, as well as the construction of new, modified, and expanded onshore gas field gathering and transportation steel pipelines with a design pressure of no more than 70 MPa.
