16、PANESE INDUSTRIAL STANDARD JIS G 3454 : 2005 Carbon steel pipes for pressure service Introduction This Japanese Industrial Standard has been prepared based on the first edition of IS0 9330-1 Welded steel tubes for pressure purposes-Technical de- livery conditions-Part l: Unalloyed steel tubes with s
17、pecified room temperature prop- erties published in 1990 and the first edition of IS0 9329-1 Seamless steel tubes for pressure purposes-Technical delivery conditions-Part 1: Unalloyed steels with specified room temperature properties published in 1989 with some modifications of the tech- nical conte
18、nts. The portions given sidelines or dotted underlines are the matters modified from the original International Standard. A list of modifications with the explanations is given in annex 2 (informative). 1 Scope This Standard specifies the carbon steel pipes (hereafter referred to as “pipes”) used fo
19、r pressure service at an approximate maximum temperature of 350 O C . The pipes for high pressure service shall be in accordance with JIS G 3455. Pertaining to the electric-resistance welded steel tubes, when previ- ously agreed upon with the manufacturer, the purchaser may desig- nate a part of all
20、 of the supplementary quality requirements specified in annex 1, in addition to the items specified in this text. 2 The International Standards corresponding to this Standard are as follows. In addition, symbols which denote the degree of correspondence in the contents between the relevant Internati
21、onal Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) ac- cording to ISO/IEC Guide 21.
