Abstract

Specifies the requirements for the safe use and proper design of a gas reticulation system, together with precautions that are necessary during the construction, operation and maintenance of reticulation systems carrying both oxygen and acetylene gases. Highlights the precautions necessary when the end-use equipment is connected for operation in a closed workshop or open-site area.

Scope

This Standard specifies requirements for the design, assembly, installation, testing, operation and maintenance of gaseous oxygen and acetylene piping, manifolds and equipment used for the reticulation of these gases in industrial and laboratory applications. It does not apply to oxygen used for breathing purposes. Also, it does not apply to oxygen and acetylene cylinders on carts. The Standard applies to the following:
(a) Piping sizes up to 38 mm NB for industrial grade oxygen at pressures not exceeding 2100 kPa, and supplied either from high-pressure (H.P.) oxygen cylinders fitted with connections which comply with AS 2473, or from an oxygen vaporizer fed from a liquid oxygen storage vessel.
(b) Piping sizes up to 32 mm NB for acetylene within the allowable pressure range for the particular NB of the piping being used, and not exceeding 150 kPa. Supply of acetylene into the piping shall be from cylinders. Piping in Items (a) and (b) shall comply with AS 4041. Future direction concerning larger piping sizes beyond those indicated in the Scope will need guidance from industry (see Preface).
