Comment on draft standards

IGEM/TD/4 Edition 5 – PE and steel gas services and service pipework

A draft of IGEM/TD/4 Edition 5 – PE and steel gas services and service pipework is available for comment.

This draft Standard IGEM/TD/4 Edition 5 has been prepared by a Panel and is submitted to industry for its consideration and comment. The draft can be found here and the comment form can be downloaded from here.

Background

This Standard addresses Natural Gas (NG) services and Liquefied Petroleum Gas (LPG) service pipework. For the purposes of this Standard, the term “service” is used throughout and any requirements unique for LPG are identified by reference to LPG and not to “service pipework”

This Standard covers the design, construction, commissioning, decommissioning, inspection, testing, operation, maintenance and alteration of metallic and PE services for the provision of 2nd and 3rd family gases as defined in BS EN 437; mainly dry NG (predominantly methane) with or without odorisation and LPG. 

Deadline

Please forward your comments on the draft standard, using the associated comment form to liya@igem.org.uk by 20 August 2021.

IGEM/UP/9 Edition 3 Application of Gas systems to gas turbines and supplementary and auxiliary fired burners

A draft of IGEM/UP/9 Edition 3 Application of Gas systems to gas turbines and supplementary and auxiliary fired burners, is available for comment.

This draft Standard IGEM/UP/9 Edition 3 has been prepared by a Panel and is submitted to industry for its consideration and comment. The draft can be found here and the comment form can be downloaded from here.

Background

This Standard covers the application of fuel gas supply to gas turbines and the exhaust gas interaction with supplementary and auxiliary fired burners.

This Standard covers the essential safety aspects of the engineering, start‑up, operation and shut‑down of gas turbines and associated equipment and refers primarily to gas turbines using lighter and heavier than air flammable fuel gases such as Manufactured Gas, Natural Gas (NG), Liquefied Petroleum Gas (LPG), LPG/air mixtures, (1st, 2nd and 3rd family gases are further defined in BS 1179). They may be appropriate for other non-conventional gases such as Landfill, Anaerobic Digester and Mines Recovery Gas and Hydrogen, but the particular characteristics of the gas needs to be recognised with respect to consequent effects on materials and operations.

This Standard applies to:

• both single and multi-shaft turbine types
• both single and multiple burner types
• turbines exhausting to heat recovery equipment, with or without supplementary and/or auxiliary fired burners, which may or may not have air supplies other than the engine exhaust. Those having independent air supplies are also considered as auxiliary fired.
