Standards Development
This document specifies the types of functions and components of a tapping point, necessary to ensure a practical, safe and efficient use of equipment for welding, cutting and allied processes connected to a gas pipeline system.
This document specifies requirements for tapping point to be connected to industrial gas distribution pipelines of: compressed gases and carbon dioxide up to 6 MPa (60 bar); acetylene up to 0,15 MPa (1,5 bar); liquefied petroleum gases (LPG); methylacetylene-propadiene mixtures (MPS); for use in welding, cutting and allied processes.
This document does not cover stand-alone line pressure regulators covered by ISO 22073-1.
NOTE Where there is no risk of ambiguity, both line pressure regulators and line pressure regulators with flowmetering devices are addressed with the collective term ‘pressure regulators’.
The reason we need this new standard is because ISO 2503 doesn’t cover the pressure regulators used on gas pipelines and distribution systems, with a lower inlet pressure than the cylinder regulators. The industry needs a standard to refer to for them. These regulators are now only covered in other standard systems like AS or CGA. In addition to ISO 22073-1 which specifies pipeline regulators, this part 2 defines the connection point, its composition and safety aspects. An ISO standard is very much needed.
