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.

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 automatic failure detection systems are installed, the practicability of automatic shutdown shall be considered. Sensitive uses are defined in some jurisdictions, but include schools, hospitals, aged care facilities and prisons. Significant changes to this edition include the following: The design shall document the controls incorporated in the design, and any operational ss required to comply with the high stress-low temperature limits.
It may be appropriate to address failures of different threat controls e.
Australian Standard AS Pipelines – Gas and Liquid Petroleum – Design and Construction
Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed The following aspects of pipeline design, construction and operation shall be considered in the design of 28851 pipeline: Operation and maintenance Part 4: The mechanical property limits of the relevant material Standard e. Residential applies where multiple dwellings exist in proximity to each other and dwellings are served by common public utilities. The stress, temperature and fracture arrest length parameters do not need to be uniform over the pipeline and may differ for each location class or for each relevant fracture mode.
The submerged class extends only to the estimated high water mark of the inundated area. The MAOP shall be approved before the pipeline is placed in operation. Significant changes to this Section include the following: Specific construction safety requirements exist in each regulatory jurisdiction.
As 2885.1-2012 Design and Construction
This standard specifies the requirements for the design and construction of pipelines used for sa transmission of liquids such as: Where strict adherence to the requirements of this Clause is shown to provide no increase in safety, alternative spacing may be developed. 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.
The isolation plan shall 28885.1 the facilities provided to perform the functions required and shall consider, as a minimum, the following items: Where this Standard is used for pipelines constructed from corrosion resistant alloy pipe, fibreglass or other materials, the fracture control plan shall be developed xs a full understanding of the 28851 behaviour of the pipe material. For the purpose of this Standard, this shall be achieved by either one of the following: For a new pipeline, SF can be estimated from knowledge of the number of heats required to manufacture the pipe in the pipeline, and from historical knowledge of the toughness distribution in similar strip manufactured by the steel mill.
An environmental impact assessment shall be conducted in accordance with this Standard along the length of the pipeline route.
The most appropriate methodologies shall be used for each facility. Location aw analysis of an existing pipeline shall take full account of current land use and authorized developments along the pipeline route, but need not take full account of land use which is planned, but not implemented.
Where signs are used to provide procedural protection, the spacing to provide effective protection shall be established in the external interference protection design in accordance with Clause 5.
An assessment shall be carried out and the following factors shall be considered: 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. Other suitable location may be a flange, a weld or a point defined by dimensions.
Accessed by Fyfe Pty Ltd on 288.51 Oct Document currency not guaranteed when printed Valves shall be installed so that, in the event of a leak, the valves can be expeditiously operated. The engineering design shall take into account the effect of all of the manufacturing and construction processes and service conditions on the properties of the materials.
The design requirements for residential shall apply. Between editions, amendments may be issued. This revision AS For existing pipelines the period for the implementation of each action shall be identified as part of the safety management documentation.
At the end of the system design life the pipeline shall be abandoned unless an engineering investigation determines that its continued operation is safe. Some of this information may be addressed in a generic manner for a given set of pipeline parameters, and does not necessarily have to be documented against every threat analysed.
Mandatory requirements are specified in high consequence areas for— i elimination 2885.1 rupture; and ii maximum energy release rate. Where materials and components do not comply with nominated standards and have been qualified in accordance with this Clause, documentary evidence of that qualification shall be provided and approved.
The temperature limit for continuous operation at a hoop stress in excess of 85 MPa shall be established and documented.
For ss pipelines, all actions that are considered necessary for the safe pressurization of the pipeline shall be completed prior to the commencement of commissioning.
For guidance for the spacing of mainline valves, see Table 4. Pipeline crossings of non-navigable waterways, rivers, creeks, and streams, whether permanent or seasonal, are included where appropriate.
Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed D That, where required by the safety management study, pipeline components have sufficient 2858.1 toughness to minimize the likelihood of fracture initiation.
The materials or components shall be approved.
The break between pipeline and station shall be defined for each station. To maintain their currency, all Standards are periodically reviewed, and new editions are published.
