This Specification is part of a series of Institution of Gas Engineers and Managers (IGEM) publications, providing a specification for selecting meter installation fittings.
This standard gives requirements for design, construction, inspection, testing, operation and maintenance of steel and polyethylene (PE) pipelines for gas distribution.
This Guide supersedes IGEM/IG/2 Edition 1. It has been drafted by a Panel appointed by the Institution of Gas Engineers & Managers’ (IGEM’s) Gas Utilisation Committee , subsequently approved by that Committee, approved by the Technical Coordinating Committee and published by the authority of the Council of the Institution. The current panel is chaired by Graham McKay.
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 Standard covers the product requirements for primary diaphragm gas meters with a maximum flow rate in the range 6 m³h-1 to 160 m³h-1 that may be purchased for installation in domestic, commercial and industrial locations.
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.
The IGEM/UP/9 standard covers the essential safety aspects of the engineering, startup, operation and shutdown of Natural Gas and fuel oil fired gas turbines and associated equipment
This Standard covers the design and application of interlock devices and associated systems used with gas appliance installations in commercial catering establishments
This standard provides requirements for design, construction, testing, commissioning, and guidelines on general operation and maintenance of CNG fuelling stations and facilities
This standard is intended for use by those concerned with the design, installation and use of gas appliances and equipment in vehicle repair and body shops
This Standard provides basic design information to enable design of gas installations which do not require the use of special equipment designed for hazardous areas
Applies to inlet pressures exceeding 38 bar and not exceeding 100 bar. These procedures give guidance on the design and usage of high accuracy meter installations of piped Natural Gas in a specific pressure range, such as compressor stations
