Specifies minimum requirements for the materials, design, fabrication, testing, inspection, reports and pre-commissioning of piping subject to internal or external pressure.

Scope

This Standard sets out minimum requirements for the materials, design, fabrication, testing, inspection, reports and pre-commissioning of piping subject to internal pressure or external pressure or both. Specific requirements are given for piping constructed of carbon, carbon-manganese, low alloy and high alloy steels, ductile and cast iron, copper, aluminium, nickel, titanium and alloys of these materials. General requirements and reference to Standards for non-metallic piping are included.
The Standard makes extensive use of AS/NZS 3992, AS 4037 and AS 4458.
This Standard applies specifically to pressure piping, i.e. piping which may present a significant risk of injury to people, property or the environment owing to hazards arising from –
(a) the effects of pressure, either as a result of internal pressure causing an explosion or projectile, or as a result of external pressure causing buckling and collapse;
(b) release of contents which are lethal, toxic, harmful to human tissue (e.g. hot, cold, corrosive) flammable, combustible or are otherwise hazardous; or
(c) release of contents which directly or indirectly result in injury or damage e.g. piping for pollutants, fire-fighting purposes or cooling purposes.
This Standard is intended to apply to the following piping except when varied by the relevant Standard:
(i) Piping for land steam boilers, prime-movers, refrigerant and other industrial plant except where the piping forms an integral part of a boiler or pressure vessel and the requirements of AS 1210 or AS 1228 apply.
(ii) Hydraulic piping, water piping (including feed water piping), process piping and water piping forming part of a fire protection system (see AS 4118 and AS 4214). See also Items (A) to (F) of this Clause.
(iii) Piping within boundaries of chemical manufacturing or processing installations, petroleum refineries, petrochemical plant, gas process plant, refinery tank farms, terminals and bulk handling plants.
(iv) Oil fuel piping within the scope of AS 1375, AS 1692 and AS 1940.
(v) Liquefied petroleum gas piping within the scope of AS/NZS 1596.
(vi) Anhydrous ammonia within the scope of AS/NZS 2022.
(vii) Low-temperature and refrigeration piping within the scope of AS/NZS 1677.
(viii) Piping for road tank vehicles within the scope of AS 2809.
(ix) Compressed air piping, the design pressure of which exceeds 70 kPa (internal) or 32 kPa (external).
(x) Piping for low pressure gas systems complying with AS 5601.
(xi) Other piping covered by Standards Australia Standards which require compliance with this Standard.
This Standard may be applied beyond the limits of application of Items (i) to (xi) where specified by the purchaser. Unless suitably referenced this Standard is not intended to apply to the following:
(A) Gas and liquid petroleum pipelines covered by AS 2885.
(B) Gas distribution pipelines covered by AS 1697 for Australia or NZS 5258 for New Zealand.
(C) Piping on shipping and aircraft.
(D) Piping used for roof or floor drains, plumbing services, sewers, domestic water and gas reticulation, and low pressure ventilation ducting.
(E) Mineral slurry pipelines which are covered by ASME B31.11.
(F) Nuclear piping.
Guidance on the scope of this Standard is given in Figure 1.1.
NOTE: Users of this Standard are reminded that it has no intrinsic legal authority, but may acquire legal standing in one or more of the following circumstances:
(a) Adoption by a government or other authority having jurisdiction.
(b) Adoption by a purchaser as the required standard of construction when placing a contract.
(c) Adoption where a manufacturer states that piping is in accordance with this Standard.
