AS 2885.1 PDF

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 system design life shall be approved. Threat of damage to the environment from operational maintenance and abandonment activities shall be identified and control measures developed. The minimum toughness any specimen is not usually specified except where the designer has a specific requirement for manufacturing control. The physical controls applied shall be demonstrated to 28885.1 the pipeline from the specified threat.

For existing pipelines the period for the implementation of each action shall be identified as part of the safety management documentation.

Safety management documentation shall be transferred from the design and construct phase of the project to the operating phase of the project in a form that enables safety management to be undertaken from the time that operation commences. Each typical design shall be subjected to the safety management process in accordance with this Standard to demonstrate that the design provides effective control for the identified threats.

Operating pressure ad and flow restriction devices are two effective methods of limiting the maximum discharge rate.

Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of the Standard. Safety controls require continuous management so that they remain effective. Size px x x x x A minimum toughness requirement for pipe DN and larger has been introduced. Thank you for interesting in our services.

For a new pipeline, the location class analysis shall be based on the land use permitted in gazetted land planning instruments. The sequence of decision making required to develop and implement a fracture control plan to ensure arrest of fast fracture shall be in accordance with Figure 4. The position and the spacing of valves shall be approved. Pipeline safety management shall be an ongoing process over the life of the pipeline. B On a downstream section This Standard recognizes the hierarchy of effectiveness of controls: There is a family of curves that can be developed for part through wall defects predicted from the failure stress of rectangular flaws, using the following equation: They shall be assessed individually to assess whether the industry or the surroundings include features that— i contain unusual threats to the pipeline; or ii contain features that may cause a pipeline failure to escalate either in terms of fire, or for the potential release of toxic or flammable materials into the environment.

The effect of cryogenic temperatures on the pipeline coating shall be considered.

As 2885.1-2012 Design and Construction

This applies to any pipelines used to carry:. It is usually unsuitable for use in pipelines, stations and pipeline assemblies unless toughness properties are specified, and specific tests are made to confirm compliance. Control is achieved by the application of multiple independent protective measures in accordance with this Standard.

The requirements for construction survey are clarified, and a minimum accuracy for asconstructed survey 22885.1 incorporated. Approval requires a conscious act and is given in writing.

A critical defect length also exists for part through wall flaws. Where the minimum requirements of Clause 5. Location class 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. Obligations on the developer of a new pipeline to document the design and construction, and to transfer this information to the pipeline operator, are clarified and expanded.

Normally replaceable components e. The amendment includes guidance on specifying fracture toughness when purchasing line pipe and includes a simplified calculation for energy release from leaks. The results of these deliberations form the basis of this revision. 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.

Once the critical defect length is known, the toughness required to control initiation can be calculated from Equation 4. 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. A safety management section shall not contain more than one location class.

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. Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed vii Where required, the maximum fluid property excursion and the duration of any excursion beyond which the fluid must be excluded from the pipeline.

The following data shall be obtained prior to conducting the environmental safety assessment: In CIC areas the dominant consideration may be the threats associated with the land use by other infrastructure operators or the higher consequences of loss of containment associated with increased transient population e.

The valve locations may 2885.1 necessarily be immediately adjacent to the river or water supply reserve. Consideration of population density includes both residents and others who spend prolonged periods in the vicinity of the pipeline as a result of their employment, recreation or any other reason.

Third edition AS Detailed information about Australian Standards, drafts, amendments and new projects can be found by visiting www. The thickness margin is required to allow the test specimen to be machined from the pipe wall. The isolation plan shall be approved prior to the pipeline or segment of the pipeline being placed in service.

Except as provided in Clause 3. 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.

For new pipelines, all actions that are considered necessary for the safe pressurization of the pipeline 2885. be completed prior to the commencement of commissioning. It may be a component of an integrated construction safety system, a construction safety case where the regulatory jurisdiction requires thisor a project or activity specific safety plan. 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.
