Many applications of industrial gases require a gas distribution system to be installed at the user's premises.

Safety considerations require that the main store for the gas, whether this be a cryogenic 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 point of use.

Such piping systems must be designed and installed in a manner which complies with relevant legislation, i.e. the Pressure Equipment Regulations 1999 (SI 1999: No. 2001). 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 select an installer who is experienced in installing pipework for industrial gas applications and who is fully conversant with this legislation.


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 - Industrial gas cylinders manifolds and gas distribution pipework (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.
