    Review of Australian Standards. To keep abreast of progress in industry, Australian Standards aresubject to periodic review and are kept up to date by the issue of amendments or new editions asnecessary. It is important therefore that Standards users ensure that they are in possession of the latestediti on, and any amendments thereto.Full details of all Australian Standards and related publications wil l be found in the Standards AustraliaCatalogue of Publications; this information is supplemented each month by the magazine TheAustralian Standard, which subscribing members receive, and which gives details of new publications,new editions and amendments, and of withdrawn Standards.Suggestions for improvements to Australian Standards, addressed to the head office of StandardsAustralia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standardshould be made without delay in order that the matter may be investigated and appropriate action taken.

    This Standard was issued in draft form for comment as DR 93005.

    PREFACE

    This Standard was prepared by the Joint Standards Australia/Standards New ZealandCommittee ME/38 on Petroleum Pipelines, to supersede AS 20181981, Liquidpetroleum pipelines , and AS 28851987, PipelineGas and liquid petroleum , as well asthe parts of AS 1697 1981, Gas transmission and distribution systems that relate to anMAOP of more than 1050 kPa or a hoop stress of more than 20%.

    This Standard is the result of a consensus among Australian and New Zealandrepresentatives on the Joint Committee to produce it as an Australian Standard.

    The objective of this Standard is to provide requirements for the design and constructionof steel pipelines and associated piping and components that are used to transmit singlephase and multiphase hydrocarbon fluids.

    This Standard is one of the following series, which refers to high pressure petroleumpipelines:

    AS2885 Pipelines Gas and liquid petroleum2885.1 Part 1: Design and construction (this Standard)2885.2 Part 2: Welding2885.3 Part 3: Operation and maintenance

    Gas pipelines with a pressure of less than 1050 kPa and a hoop stress of less than 20% arecovered by AS 1697, and it is intended to publish a new Standard to cover low pressureliquid pipelines.

    The terms normative and informative have been used in this Standard to define theapplication of the appendix to which they apply. A normative appendix is an integralpart of a Standard, whereas an informative appendix is only for information andguidance.
