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.

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.
Specific construction safety requirements exist in each regulatory jurisdiction. The following data shall be obtained prior to conducting the environmental safety assessment: External interference protection shall be designed in accordance with Clause 5.

Where automatic ae detection systems are installed, the practicability of automatic shutdown shall be considered. The purpose of the test is to eliminate the risk of failure of the pipe during the strength test. The principles are expressed in practical rules and guidelines for use by competent persons.
C The longitudinal weld seam weld metal and HAZ of line pipe has adequate levels of fracture toughness to minimize the likelihood of fracture initiation. A value of 1.

The duration of new MAOP shall be nominated at the time of re-test, based on an analysis of the measure rate of degradation of the pipeline at 2885.
expected operating conditions. This revision provides more explicit guidance on the obligation to undertake safety assessments with the integrity required for compliance with this Standard. Where the existing pipeline does not comply with either Clause, mitigation shall be applied in accordance with Clause 4. This Clause shall not be construed as permitting deviations that would tend to adversely affect the properties of the material. The requirements of Section 6 shall apply where an element of the pipeline has been designated as a station.
Please consult the responsible agency for more information and to ascertain the level of compliance if any that may be required.
As 2885.1-2012 Design and Construction
The design shall consider each operating condition that has the potential to cause temperatures lower than the minimum design ss of the pipeline, or its components.
Where other threats are identified, effective controls shall be applied to each of these additional location specific threats. The environmental impact assessment report shall form the basis of the environmental management plan. Where a trigger point relates to a part of the pipeline for example a change at a specific location or a specific safety aspectthe safety management study may be restricted to only that 28851 which is changed.
Because higher levels of toughness are required to a propagating fractures than are required to avoid the initiation of a fracture, the specification of sufficient toughness to control fast fracture propagation will always ensure that the pipe body will be sufficiently tough so that initiation is flow stress controlled rather than aas.
The information requirements listed in Paragraph B3, Appendix B, shall be considered in the validation workshop. The purpose of the design basis is to document both principles and philosophies that will be applied during the development of the detailed design, and specific design criteria that will be applied throughout the design.
Where the limits sa the anticipated land use change can reasonably be determined, the pipeline location classes shall be based on the anticipated land use. Under some circumstances the predictions of arrest toughness are known to be non-conservative—in this case the calculated arrest toughness shall be multiplied by a factor of safety determined by experience or by full scale burst test.
A code of practice can be defined as a result of legislation or by industry regulators and bodies. The safety management process and its outcomes shall be documented and approved. The appropriate authorities shall be contacted to obtain details of any known or expected development or encroachment along the route, the location of underground obstructions, pipelines, services and structures and all other pertinent data.
Industrial location class shall be assigned to any portion of pipeline where the immediately adjoining land use is industrial.
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: Control is achieved by the application of multiple independent protective measures in accordance with this Standard.
Land used for other purposes but with similar population density shall be assigned rural residential location class. The location of valves shall be determined for each pipeline.
Field pressure testing Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed —Minor revision harmonization with other parts This minor revision of AS Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed Low temperatures caused during pressure changes in commissioning or in operation shall be considered in the fracture control plan.
This review shall take the form of a construction safety plan workshop.
