This Standard specifies requirements for the alloy steel pipes (hereafter referred to as pipes) mainly used for piping at elevated temperatures.
NOTE 1 This Standard is generally applied to pipes of outside diameter 10.5 mm (nominal diameter 6A or 1/8B) to 660.4 mm (nominal diameter 650A or 26B) (see 9.1).
NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 9329-2:1997 Seamless steel tubes for pressure purposes-Technical delivery conditions-Part 2: Unalloyed and alloyed steels with specified elevated temperature properties (MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
