Synopsis of IGEM/TD/1 Edition 6 with amendments May 2024:
This Standard supersedes Edition 6, Communication 1848, published in 2021. It has been approved by the Gas Transmission and Distribution Committee (GTDC) and published by the authority of the Council of IGEM.
Pressure regulating installations (PRIs) for new and repurposing of existing PRIs for transmission of Natural Gas (NG)/Hydrogen blends for pressures not exceeding 7 bar
This Reference Standard is aligned to IGEM/TD/13 Edition 3 and aims to identify and discuss the principles required for the safety and integrity of Hydrogen pressure regulating.
This Reference Standard addresses the issues arising from the proposal to distribute Hydrogen through existing NG steel and PE pipelines (mains and services) repurposed for Hydrogen service at pressures not exceeding 7 bar.
This Reference Standard addresses the issues arising from the proposal to distribute Hydrogen through steel and polyethylene (PE) pipelines (mains and services) at pressures below 7 bar. Where the term pipeline is used, it applies to both mains and services; specific requirements for mains and services will be specified as mains or services.
This Supplement gives additional requirements and qualifications for the distribution of Natural Gas/Hydrogen blended mixtures, and for the repurposing of Natural Gas pipelines for NG/H blends and is only to be used in conjunction with IGEM/TD/3 Edition 5.
This standard covers the design, construction, installation, testing, operation, inspection, maintenance and decommissioning of biomethane network entry facilities (BNEFs)
This standard outlines the minimum management requirements for laying newly constructed natural gas mains and services including associated installations such as pressure regulating installations of maximum operating pressure 7 bar for adoption by a gas transporter
Covers the handling, transport and storage of steel pipe and highlights precautions to control steel pipe products being delivered, off-loaded and stored safely at customers' sites
This standard gives requirements for design, construction, inspection, testing, operation and maintenance of steel and polyethylene (PE) pipelines for gas distribution.
