Where gases are stored and used there is usually a requirement for a gas distribution system to be installed.

Safety considerations require that the main store for the gas, whether this be a storage tank or gas cylinders, is located outside in a secure, well ventilated position, away from any sources of ignition. A system of piping is then provided to transfer the gas to the points of use.

Such piping systems must be designed and installed in a manner which complies with relevant legislation, i.e. the Pressure Equipment (Safety) Regulations 2016 (SI 2016: No. 1105). Once installed they must be documented and maintained in accordance with the Pressure Systems Safety Regulations 2000 (SI 2000: No. 128).

Gas users who need to have a gas distribution system installed on their premises are strongly recommended to work with a Designer who has relevant design experience and to select an Installer experienced in installing pipework for industrial, medical and food gas applications, both of whom are fully conversant with this legislation and industry codes of practice (as detailed below).


Within BCGA pipework is the responsibility of Technical Sub-Committee (TSC) 1. Members can access information on TSC1 via the ‘Members' area.


Several BCGA publications provide advice on pipework within their specialist subject areas. All BCGA publications are accessible via the ‘Publications' page. The following publications provide specific advice on pipework:

  • BCGA CP 4 Gas supply and distribution systems (excluding acetylene).
  • BCGA CP 5 - The design and construction of manifolds using acetylene gas from 1.5 bar to a maximum working pressure of 17 bar.
  • BCGA CP 6 - The safe distribution of acetylene in the pressure range 0 to 1.5 bar.
  • BCGA CP 39 - In-service requirements of pressure equipment (gas storage and gas distribution systems).
