Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and

systems. To maintain their currency, all Standards are periodically reviewed, and

new editions are published. Between editions, amendments may be issued.

Standards may also be withdrawn. It is important that readers assure themselves

they are using a current Standard, which should include any amendments which

may have been published since the Standard was purchased.

Detailed information about Standards can be found by visiting the Standards Web

Shop at www.standards.com.au and looking up the relevant Standard in the on-line

catalogue.

Alternatively, the printed Catalogue provides information current at 1 January each

year, and the monthly magazine, The Global Standard , has a full listing of revisions

and amendments published each month.

Australian Standards TM and other products and services developed by Standards

Australia are published and distributed under contract by SAI Global, which

operates the Standards Web Shop.

We also welcome suggestions for improvement in our Standards, and especially

encourage readers to notify us immediately of any apparent inaccuracies or

ambiguities. Contact us via email at mail@standards.org.au, or write to the Chief

Executive, Standards Australia, GPO Box 5420, Sydney, NSW 2001.

This Standard was issued in draft form for comment as DR 04330.

PREFACE

This Standard was prepared by the Australian members of the J oint Standards

Australia/Standards New Zealand Committee ME-002, Gas Cylinders to supersede

AS 2469—1998, Steel cylinders for compressed gases—Welded two-piece construction—

0.1 kg to 35 kg . After consultation with stakeholders in both countries, Standards Australia

and Standards New Zealand decided to develop this Standard as an Australian, rather than

an Australian/New Zealand Standard.

This Standard is one of a suite of three Standards for welded and brazed cylinders for

compressed gases, the other Standards being as follows:

AS

2470 Steel cylinders for compressed gases—Welded three-piece construction with

longitudinal joint—11 kg to 150 kg

3577 Steel cylinders for compressed gases—Welded—150 kg to 500 kg

This Standard provides for gas cylinders produced in large quantities. Users of this

Standard should note that a competent person or body will require either quality control

procedures to be employed at the point of manufacture in Australia, or, for cylinders

manufactured overseas, sampling and testing at the point of entry into Australia. It should

also be noted that before a gas cylinder can be first filled in Australia it must be stamped

with a Certificated Gas Cylinder Test Station registered mark in accordance with the

relevant Standard in the AS 2030 series.

The construction requirements now allow two piece welded cylinders to be made with

capacities up to 150 kg water capacity. This brings this Standard into alignment with

ISO 4706, Refillable welded steel gas cylinders .

The terms ‘normative’ and ‘informative’ have been used in this Standard to define the

application of the appendix to which they apply. A ‘normative’ appendix is an integral part

of a Standard, whereas an ‘informative’ appendix is only for information and guidance.

STANDARDS AUSTRALIA

Australian Standard

Steel cylinders for compressed gases—Welded two-piece

construction—0.1 kg to 150 kg

1 SCOPE

This Standard specifies requirements for welded carbon and stainless steel cylinders with no longitudinal joint and one circumferential joint, of water capacity not less than 0.1 kg nor more than 150 kg, which have test pressures from 1750 kPa to 7000 kPa and are intended for the storage and transport of compressed gases in accordance with AS 2030.1. Requirements for pneumatic testing are given in Appendix A.

NOTES:

1 A gas cylinder manufactured by welding but which includes any brazing of, or on, the pressure-retaining portions is for the purpose of this Standard considered to be a brazed gas cylinder.

2 Other Australian Standards for brazed and welded gas cylinders are AS 2468, AS 2470, and AS 3577.

3 Appendix B lists the suggested minimum information that should be supplied by the purchaser when ordering gas cylinders to this Standard. 2 REFERENCED DOCUMENTS A list of documents referred to in this Standard is given in Appendix C. 3 DEFINITIONS For the purpose of this Standard, the definitions given in AS 2030.1 and those below apply. 3.1 Attachment Any fitting attached to the pressure-retaining sections of the cylinder by welding, including

bosses, pads, valve protection rings, and footrings.

3.2 Inspection Body

A body responsible for inspection, which may cover any one or more of the following: (a) Design verification.

(b) Fabrication inspection.

(c) In-service inspection.

3.3 Inspector

A person, acceptable to the competent person or body, who ensures and certifies that all the inspections specified herein have been carried out and that the cylinders comply with all the requirements of this Standard.

4 MATERIAL

4.1 Steelmaking process

The steel shall be made by the open hearth, basic oxygen, or an electric process, and shall be continuously cast. Production by the use of ingots is acceptable provided the steel is fully killed. Rimmed steels shall not be used for arc welded components.
