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.

Mandatory requirements are specified for control of external interference threats which are known to be the most frequent events with the potential to create a failure.

For the purpose of this Standard, this shall be achieved by either one of the following: Pressure strength for a pipeline or a section of a pipeline is the minimum of the strength test pressures of the test sections 2858.1 the pipeline or the section of the pipeline.
Great care and skill is necessary in the achievement of proper notch locations. Appropriate management actions may be required to minimize non-failure consequences. Industrial location class shall be assigned to any portion of pipeline where the immediately adjoining land use is industrial. The residual risk of such threats shall be assessed and treated in accordance with Appendix F. The duration of new MAOP shall be nominated at the time of re-test, based on an analysis of the measure rate of 285.1 of the pipeline at its expected operating conditions.
This revision AS It is important that readers assure themselves they are using a current Standard, which should include any amendments that may have been published since the Standard was published.
The requirements of this Standard complement the requirements of regulatory authorities in assessment and management of environmental risk, and are intended to be used during planning construction and operational phases of 28851. pipeline to ensure that— a environmental management effort is concentrated on significant threats; b environmental management methods are assessed holistically for their contribution to minimizing the impact to the environment; and c there is a basis for assessing alternative construction and management methods to minimize the impact of the environment Effective environmental impact assessment requires gathering basic environmental data and shall include consultation with key stakeholders at an early stage so that all relevant information required for all subsequent planning is available.
This Clause sets out the minimum requirements for compliance with this Standard in high consequence areas. 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. You will be required to comply with this standard if you intend to construct a pipeline.
Significant changes to this Section include the following: The reduction in yield strength shall be 0.

Some rich gas compositions require higher arrest toughness at temperatures higher than the design minimum temperature. It specifies strength test endpoint requirements for pipelines with a pressure design factor of 0. It is usually unsuitable for use in pipelines, 28855.1 and pipeline assemblies unless toughness properties are specified, and specific tests are made to confirm compliance. The average of all Charpy impact test toughness tests determined on the pipe population supplied to the order at the frequency nominated in the pipe specification must not be less than the minimum toughness all heat average.
Additional guidance is provided on treatment of lightning, together with some clarifying revisions to the text. The effect of material processing on strength, ductility and fracture properties shall be determined by representative tests on samples subjected to simulated or actual heat treatment cycles and taken into consideration in the design, including the fracture control plan.

The design basis shall be revised during the development of the project to record changes required to the design basis as a result of additional knowledge of the project requirements as the detailed design is developed. For pipelines in which the calculated arrest toughness CVN exceeds J, the method of achieving arrest within the design length shall be the subject of an independent expert verification. Standards may also be withdrawn. Land 2885. for other purposes but with similar population density shall be assigned rural residential location class.
Design lives include the following: This section describes its detail and application. A GIS with quality aerial photography and themes showing the radiation contour for full bore rupture, cadastre, and land planning zones is a valuable tool in determining the location class.
Equipment shall be provided for evacuation of the fluid from a 2885.1 where required for maintenance and ws repairs after a loss of containment.
An assessment shall be carried out and the following factors shall be considered: Where signs are used to provide procedural ss, the spacing to provide effective protection shall be established in the external interference protection design in accordance with Clause 5.
Provided that qs consideration is given in the design to the effects of any adverse conditions under which the pipe had previously been used, the reclaimed pipe may be treated as new pipe to the same Standard only after it has passed a hydrostatic test see 288.51 3. Consideration shall be given to the need in subsequent operation, maintenance and development of the pipeline for the materials to be identified spatially, by item e.
Flattened strap test pieces shall not be used 285.1 yield strength determination. Guidance on design for environment related cracking is provided in Appendix P. This Standard recognizes the hierarchy of effectiveness of controls: General guidance on electrical safety is given in Appendix R.
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.
For new pipelines, or modifications to existing pipelines, the detailed design and the safety management study are undertaken as integrated iterative processes. Research on yield to tensile ratio and its causes and effects has been undertaken by APIA and recommendations adopted in this Standard.
The principles are expressed in practical rules and guidelines for use by competent persons. Rural residential includes areas of land with public infrastructure serving the rural residential use; roads, railways, canals, utility easements. Controls are considered effective when failure as a result of that threat has been removed for all practical purposes at that location. Where the minimum requirements of Clause 5. Pressure-containing components that are not covered by nominated Standards or not covered by design equations or procedures in this Standard may be used, provided the design of similarly shaped, proportioned and sized components has been proved satisfactory by successful performance under comparable service conditions.
Sensitive uses are defined in some jurisdictions, but include schools, hospitals, aged care facilities and prisons. Where the measured hydrostatic test pressure is to be used to confirm a pressure limit, the engineering design shall be critically reviewed to determine that all aspects of the design components are suitable for the target pressure limit to be confirmed prior to the hydrostatic pressure test being carried out.
The control failure threat s should be at a location where the consequences are most severe.
