This standard covers the fabrication, installation, testing and commissioning for flow rate exceeding 6 m3h-1 and inlet pressure up to and not exceeding 38 bar
The Gas Distribution Networks (GDN’s) have been collaboratively working with the ENA and the biomethane service providers to develop a set of Site Acceptance Testing (SAT) requirements/methodologies to provide consistency of application and drive efficiencies across the biomethane sector.
This Specification gives the requirements for the weldability testing of fittings for service in pipelines and pipework of carbon and carbon-manganese based steels at pressures above 7 bar.
This Gas Industry Standard (GIS) gives requirements for equipment used in testing buried and exposed gas mains and gas services with operating pressures not greater than 7 bar, operating at low pressure (LP), medium pressure (MP) and intermediate pressure (IP), as well as internal pipework and metering arrangements downstream of the emergency control valve.
This standard covers the design, construction, installation, testing, operation, inspection, maintenance and decommissioning of biomethane network entry facilities (BNEFs)
This specification specifies fusion bonded epoxy powders and multi-component liquid materials for use as anti-corrosion coatings on steel line pipe and fittings (tees and bends) used for the transmission and distribution of natural or manufactured gas as defined in ISO 13623.
This standard gives requirements for design, construction, inspection, testing, operation and maintenance of steel and polyethylene (PE) pipelines for gas distribution.
This part of GIS/PL2 specifies requirements for polyethylene pipes, with a strength classification of PE100 1) in the nominal size range 16 mm to 800 mm inclusive for use at operating pressures not greater than 7.0 bar and operating temperatures in the range of 0 °C to 40 °C.
This part of the GIS/PL2 suite of documents specifies requirements for nominally yellow polyethylene pipes, with a strength classification of PE80 1) in the nominal size range 16 mm to 800 mm inclusive for use at operating pressures not greater than 5.5 bar and operating temperatures in the range −20 °C to 40 °C.
Our gas network is one of the best developed in the world, providing safe, secure, affordable energy to homes and businesses across the UK. To meet the biggest energy challenge of our generation – making deep cuts to carbon emissions by 2050 – we need to embrace new technology which builds on these strengths and delivers the integrated, flexible network of the future.
This specification provides requirements for the welding of steel land pipelines, designed to carry non sour dry natural gas and to operate at pressures greater than 7 bar; in accordance with IGEM/TD/1 in the UK, or IS 328 in the Republic of Ireland. This specification details the requirements for the welding of carbon, carbon manganese and low alloy steel pipelines with specified minimum yield strengths (SMYS) not exceeding 555 N/mm2 (i.e., grade L555 or X80).
This has developed and agreed a list of required site acceptance tests to allow biomethane sites to demonstrate their compliance to FWACV and GS(M)R regulation.
