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.
Typical data sources used to conduct the threat identification include alignment survey data to determine basic geographical information; land user surveys in which land liaison officers gather information from land users on the specific activities carried out on the land, and obtain any other local knowledge; third-party spatial information GIS type data on earthquakes, drainage, water tables, soil stability, near-surface geology, environmental constraints, etc.
Once the critical defect length is known, the toughness required to control initiation can be calculated from Equation 4. 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 a 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.
A code of practice can be defined as a result of legislation or by industry regulators and bodies. Where erosion or erosion-corrosion mechanisms exist and where these mechanisms can be controlled by limiting the maximum velocity in the pipeline, the maximum velocity in the transmission pipeline and in the station piping shall be determined and documented in the design basis.
The Licensee shall ensure that pipeline safety management activities are carried out by suitably qualified, trained and experienced personnel. The amendment includes guidance on specifying fracture toughness when purchasing line pipe and includes a simplified calculation for energy release from leaks.
The design basis is usually an output of the planning and preliminary design phase of a project. Replaceable components may have a lesser design life, reflecting the ease with which the component can be maintained, without impacting on the safe operation of the pipeline. The position and the spacing of valves shall be ae.
2858.1 The mechanical property limits of the relevant material Standard e. The validity of this decision shall be considered at each review of safety management study.

Where this Standard is applied to fluids other than gas and liquid petroleum, a gap analysis shall be conducted to identify the differences between the www. The location of valves shall be determined for each pipeline. The thickness terms used in this Standard are clarified. The reason for it being declared non-credible shall also be documented.
As 2885.1-2012 Design and Construction
Mandatory requirements are specified in high consequence areas for— i elimination of rupture; and ii maximum energy release rate. The following shall be considered in developing an appropriate marking strategy for the pipeline: Environmental studies may be required by the relevant authority. This revision AS Ad shall be cleaned, examined and where required reconditioned and tested, to ensure that they comply with this Standard.
Accessed by Fyfe Pty Ltd on 18 Oct Document currency not guaranteed when printed The MAOP of a pipeline is conditional a the integrity of the pipeline established by hydrostatic testing being maintained throughout the operating life and on the design assumptions used to derive the design pressure.
In rural and rural 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 outcomes of the safety management study shall be incorporated in the pipeline management system. All reasonably practicable controls should be applied.
The minimum toughness any specimen is not usually specified except where the designer has a specific requirement for manufacturing control. The environmental management plan 28851 include procedures for protecting the environment from constructions, operation maintenance and abandonment activities.
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.
Threats common to typical designs shall be documented. Signs and buoys shall be appropriately located to advise the public of any danger and to minimize any risk of damage to shipping.
For new pipelines, or modifications to existing pipelines, the detailed design and the safety management study are undertaken as integrated 28851. processes. 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 22885.1 similar strip manufactured by the steel mill.
The design basis shall record, as a minimum, the following: The notch should be located within 0. Pipeline crossings of non-navigable waterways, rivers, creeks, and streams, whether permanent 28885.1 seasonal, are included where appropriate.
The threats to be considered shall include, at least— a external interference, b corrosion, c natural events, d electrical effects, e operations and maintenance activities, f construction defects, g design defects, h material defects, i intentional damage, and j other threats such as seismic and blasting.
Non-credible threats do not require controls. The most appropriate methodologies shall be used for each facility. It shall not apply to pipeline accessories, which are addressed in Clause 3. In high consequence locations where loss of containment can result in 8285.1 fires or vapour cloud fires the maximum discharge rate shall be determined and shall be approved.
All threats to the integrity of the pipeline shall be identified and multiple independent controls shall be applied to each identified threat. Fittings shall be designed to withstand the pipeline strength test pressure and shall be hydrostatically tested with the pipeline.

The revision also reflects the results of a significant and ongoing industry funded research program undertaken by the Australian Pipeline Industry Association and its research contractors, and through its association with the Pipeline Research 2885.1 International and the European Pipeline Research Group.
For these fluids the 4. The Qs has been expanded to require the Design Basis for stations to be documented. Where the outcome is failure, the analysis shall determine the mode of failure and if applicable, the energy release rate at the point of failure, as inputs to the consequence analysis.
