AS — Australian Standard®. Pipelines—Gas and liquid petroleum. Part 1: Design and construction. Accessed by Fyfe Pty Ltd on 18 Oct You will be required to comply with this standard if you intend to operate a distribution system. A distribution system is a system of pipelines, mains, and gas . Could anyone of you please post the AS standard that’s meant for ” Pipelines – Gas and liquid petroleum – Design and construction”??? in which i need to.

It shall not apply to pipeline accessories, which are addressed in Clause 3. Where the steel grade is X80, the specified toughness shall be 28851 least the calculated toughness multiplied by 1.
The design shall consider each operating condition that has the potential to cause temperatures lower than the minimum design temperature of the pipeline, or its components.

Submarine or offshore pipelines are designed to AS In sensitive use areas, the societal qs associated with loss of containment is a dominant consideration. Where appropriate, one or more secondary location classes reflecting special land uses shall be allocated to locations along the route.

Where this Standard is applied to 2858.1 other than gas and liquid petroleum, a gap analysis shall be conducted to identify the differences between the www. The effect of exposure to the design maximum temperature on the competing processes of increased strength due to strain ageing and loss of strength due to the elevated temperature shall be considered.

Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed Where land use changes from a low consequence area to a high consequence area, this Standard applies mandatory requirements for maintaining the risk at an acceptable level. A new pipeline shall be designed in accordance with the requirements of this Standard— a for the land use existing at the time of design; and b for the future land use that can be reasonably determined by research of public records and consultation with land planning agencies in the jurisdiction through which the pipeline is proposed.
Land used for other purposes but with similar population density shall be assigned Residential location class. The pipeline Licensee shall maintain the records until the pipeline is abandoned or aas.
Rural includes areas of land with public infrastructure serving the rural use; roads, railways, canals, utility easements.
Significant changes in this revision include the following: The materials or components shall be approved. In heavy industrial use areas the dominant consideration may be the threats associated with the land use or a range of location specific risks associated with the loss of containment. Pressure strength for a pipeline or a section of a pipeline is the minimum of the strength test pressures of the test sections comprising the pipeline or the section of the pipeline.
This Standard was published on 20 September The design process shall be 28851. in parallel 22885.1 and as an integrated part of the safety management process and shall reflect the obligation to provide protection for the pipeline, people, and the environment. Modes of failure include rupture as a running crack in brittle fracture mode, rupture as a ductile tear, hole, pinhole, crack, dent, and gouge, loss of wall thickness. The control failure threat s should be at a location where the consequences are 285.1 severe.

Test specimens may be taken from finished pipe or, after correlation has confirmed any effect of pipe making, may be taken from the strip or plate from which the pipes are made. Mandatory requirements are specified in high consequence areas for— i elimination of rupture; and ii maximum energy release rate.
All pipelines must be constructed in accordance with this standard, and with Australian Standard AS The individual engineering design lives shall be considered when preparing operating and maintenance plans and safety management studies.
The objective of this Standard is to provide requirements for the design and construction of steel pipelines and associated piping and components that are used to transmit single-phase and multi-phase hydrocarbon fluids.
Exposure to above ambient temperatures during operation such as downstream of compressor stations or in hot oil, or gas gathering service may also affect material properties. In rural and aa residential areas, consideration shall be given to whether a higher location class may be necessary at any location where a large number of people may be present for a limited period. The Section establishes a structured methodology for demonstrating the pipeline fitness and, once approved, for commissioning the pipeline at the new pressure.
For a pipeline transporting hydrocarbon liquid 22885.1 heavier than air gases, the measurement distance may be variable. The limits for each stress condition are tabulated and normative and informative appendices are provided incorporating the relevant equations.
For new pipelines, or modifications to existing pipelines, the detailed design and the safety management study are undertaken as integrated iterative processes. Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed Where the identified hole size is small relative to the diameter of the pipe. Typical isolation valve requirements are as follows: There are circumstances where 2885.1 estimation using quantitative methods is required to enable comparison of alternative mitigation measures as a basis for demonstration of ALARP, and in some jurisdictions, to satisfy planning criteria.
