AvailableSuperseded

An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by Intertek Inform as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.

The intent of this Standard is to provide for the protection of the general public, gas distribution network operating personnel and the environment, and to ensure safe and reliable operation of gas distribution networks that reticulate gas to consumers. It covers steel piping within gas distribution networks covered by AS/NZS 4645.1, where the maximum allowable operating pressures up to or equal to 1050 kPa and the hoop stress is less than or equal to 20 percent SMYS of the pipe. Steel piping systems for gas outside these limits are generally covered by the AS 2885 suite of Standards and for some jurisdictions. AS/NZS 4645.1 provides for limited use up to 1965 kPa.

This Standard specifies materials, design, construction, installation, testing and maintenance requirements for steel piping systems and shall be used in conjunction with AS/NZS 4645.1, for the distribution of fuel gas suitable for domestic, commercial or industrial uses, where - (a) the pressure of the gas is not greater than 1050 kPa and the operating temperature range of the materials is from (30°C to 120°C; operating pressures above 1050 kPa are covered by AS 2885; and(b) where the hoop stress level is not greater than 20% of the Specified Minimum Yield Stress (SMYS) of the pipe used in that system.NOTE: The relevant statutory authority may regard this standard as appropriate for other than fuel gas.The requirements apply to the life cycle of new assets in new or existing systems, but the Sections on materials and components, welding, pressure testing and maintenance are suitable for application to existing assets in existing systems.
