JSA JIS G 3460

Abstract

This Standard specifies the steel tubes (hereafter referred to as "tubes") used for piping at exceptionally low temperatures of freezing point or under. <br>It is generally applicable to tubes of outside diameter 10.5 mm (nominal diameter 6A or 1/8B) to 660.4 mm (nominal diameter 650A or 26B). <br>In addition to the items specified in the text, the purchaser can designate special quality requirements upon previous agreement with the manufacturer, which are shown in Annex JA. <br>NOTE 1 Austenitic stainless steel tubes specified in <strong>JIS G 3459</strong> and <strong>JIS G 3468</strong> can be used for steel tubes for low temperature service. <br>NOTE 2 The International Standards corresponding to this Standard and the symbol which denotes the degree of correspondence are as follows. <br>ISO 9329-3 : 1997 <em>Seamless steel tubes for pressure purposes Technical delivery conditions - Part 3 : Unalloyed and alloyed steels with specified low temperature properties</em> <br>ISO 9330-3 : 1997 <em>Welded steel tubes for pressure purposes Technical delivery conditions - Part 3 : Electric resistance and induction welded unalloyed and alloyed steel tubes with specified low temperature properties</em> (Overall evaluation: MOD) <br>The symbols which denote the degree of correspondense in the contents between the relevant International Standards and <strong>JIS</strong> are <strong>IDT</strong> (identical), MOD (modified) and NEQ (not equivalent) according to <strong>ISO/lEC Guide 21 -1</strong>.
