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.

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.
Equipment shall be provided for evacuation of the fluid from a pipeline where required for maintenance and for repairs after a loss of containment.
Reliability and limit state design methods are permitted for pipeline design and integrity analysis, using approved methods.
The design process shall be undertaken in parallel with and as an integrated part of the safety management process and shall reflect the obligation to provide protection for the pipeline, people, and the environment.

As 2885.1-2012 Design and Construction
Typical isolation valve requirements are as follows: The submerged class extends only to the estimated high water mark of the inundated area. Designs that limit the maximum hole size may also be used to effectively control the maximum discharge rate. Flattened strap test pieces shall not be used for yield strength determination.
Research on yield to tensile ratio and its causes and effects has been undertaken by APIA and recommendations adopted in this Standard. The Section has been expanded to require the Design Basis for stations to be documented.
For guidance on measures that may be implemented, see Appendix R.
It is required to define the arrest length specified in Table 4. 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. In high consequence locations where loss of containment can result in jet fires or vapour cloud fires the maximum discharge rate shall be determined and shall be approved.
The isolation plan shall define the facilities provided to perform the functions required and shall consider, as a minimum, the following items: The following shall apply: Where other threats are identified, effective controls shall be applied to each of these additional location specific threats.
However, each such component shall be marked with the name or mark of the manufacturer and the markings specified in the Standard to which the component was manufactured.

The Section establishes a structured methodology for demonstrating the pipeline fitness and, once approved, for commissioning the pipeline at the new pressure. Since padding and backfilling are two activities that impact on the pipeline integrity, this revision incorporates additional requirements for these activities reflecting outcomes from APIA research on backfilling.
In industrial use areas the dominant consideration may be the threats associated with the land use or the societal risk associated with the loss of containment.
A location class change to Heavy Industrial requires compliance with this Clause only when pipeline failure in this location would create potential for consequence escalation.
The schedule for implementation shall be approved.
Interpolation may be made between similarly shaped proven components with small differences in size or proportion. Consequently, the threats and failure outcomes are normally different than those for a pipeline.
An environmental impact assessment shall be conducted in 2885.11 with this Standard along the length of the pipeline route. Downstream equipment should also be considered. An assessment shall be carried out and the following factors shall be considered: This review shall take the form of a construction safety plan workshop. Subject to approval, this requirement may be demonstrated by correlation between one of those tests and the results of flattened bar tests.
The materials or components shall be approved. 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 its expected 2885.1 conditions. 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.
Depending on the assessed severity the design, requirements of R2, T1 or T2 shall be applied. Pipeline crossings of non-navigable waterways, rivers, creeks, and streams, whether permanent or seasonal, are included where appropriate. 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.
This revision provides more explicit guidance on the obligation to undertake safety assessments with the integrity required for compliance with this Standard. Rural residential includes areas of land with public infrastructure serving the rural residential use; roads, railways, canals, utility easements. The design shall consider each operating condition that has the potential to cause temperatures lower than the minimum design temperature of the pipeline, or its components.
Consequently, there is no change in consequence whether fast tearing fracture in this pipe is arrested within the initiating pipe, or in a connecting pipe. 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.
