PREFACE This Standard was prepared by the Standards Australia’s Committee on Steel Pipes and Fittings–Water and Gas to supersede AS 1074–1980, Steel tubes and tubulars threaded or suitable for suitable for threading with pipe threads of Whitworth form . This edition adopts the descriptions, dimensions dimensions and masses masses as specified specified in BS 138:1985, Specification for Specification for scr ewed ewed and socketed steel tubes and tubulars and for plain end steel tubes suitable for welding or for scr ewing ewing to BS 21 pipe threads threads. This Standard does not indicate the services for which the tubes are appropriate. Where the use of tubes is not controlled by by–laws or regulations, reference should be made to the appropriate Code of Practice or application Standard. Some Codes of Practice for building relating to town gas and water, and also the relevant by–laws, preclude the use of light tubes for these services. If the application is for pressure purposes, reference should be made to AS CB18, AS CB18, SAA Pressure Piping Code–Part 1: Ferr ous ous piping.
