Australian Standard AS 2885.5 provides the requirements for field pressure testing of high pressure gas and liquid petroleum pipelines and may be used for high integrity testing of pipelines designed to other Standards.
AS 2885 has been accepted by the Council of Australian Governments (COAG) as the single and sufficient standard for the technical regulation of pipelines in all Australian jurisdictions. The AS 2885 set of standards comprises five parts covering all aspects of pipeline design, construction, operation and maintenance.
The 2012 revision of Part 5 incorporates significant changes for safe field pressure testing of pipelines designed to AS 2885.1.
Since 2007, this Standard has permitted a pressure design factor of 0.8, which in turn requires field pressure testing to a minimum strength test pressure equivalent to 100% of the specified minimum yield strength of the pipe material. AS 2885.5 (2012) introduces new requirements to ensure that plastic strain during pressure testing is controlled to safe limits, and it has required changes to the obligations of the pipeline designer.
This Seminar will inform participants of the reasons and technical basis for the changes, it will highlight specific requirements for pipeline designers and test engineers, and will introduce a software tool (PIPESTRAIN), developed by APIA for analysis of pipelines which have the potential to undergo plastic strain during the strength test.
The objectives of this seminar are:
- To provide the industry with a general overview of AS 2885 Part 5
- To educate the industry on the most important elements of AS 2885 Part 5, and the necessary interaction between design for pressure testing (AS2885 Part 1) and the pressure test (AS 2885 Part 5)
- To introduce the specific requirements for hydrostatic test design and the use of the software tool (PIPESTRAIN) to potential users.
Who should attend?
This is a vital opportunity for all industry personnel involved in the design and pressure testing of Gas and Liquid Petroleum Pipelines to demonstrate that the pipeline has the strength and integrity for its safe operation in accordance with the Standard, and in compliance with Regulatory provisions of the relevant Licence.
The Seminar will be useful to Pipeline Operators, Pipeline Regulators and also to designers of high pressure slurry pipelines (to ASME B31.11/ASME B31.4 (2012) or AS 2885).
