ISO 22073-1:2024

Gas welding equipment — Part 1: Line pressure regulators and line pressure regulators with flow-metering devices for gas distribution pipelines up to 6 MPa (60 bar)

This document specifies requirements for line pressure regulators and line pressure regulators with flow-metering devices to be connected to industrial gas distribution pipelines of:

—???? compressed gases and carbon dioxide up to 6?MPa (60?bar);

—???? acetylene up to 150?kPa (1,5?bar);

—???? liquefied petroleum gases (LPG);

—???? methylacetylene-propadiene mixtures (MPS);

for use in welding, cutting and allied processes.

This document does not apply to pressure regulators intended for direct use on cylinders or bundles, such regulators are addressed in ISO?2503 or ISO?7291, respectively.

NOTE??????????? Where there is no risk of ambiguity, both line pressure regulators and line pressure regulators with flow-metering devices are addressed with the collective term ‘pressure regulators’.
