This document provides guidelines for periodic inspections of manual gas equipment for welding, cutting and allied processes placed downstream of the gas cylinder’s valve as shown in Figure 1 or, in the case of centralized distribution, downstream from the tapping point, since commissioning.
NOTE In some cases, gas cylinders can be replaced by cylinder bundles.
This document applies to gas welding equipment intended for professional use which utilizes compressed gases up to 300 bar (30 MPa): acetylene, liquefied petroleum gas (LPG), methylacetylene-propadiene mixtures (MPS) and carbon dioxide (CO2) and related mixtures.
