This Standard specifies the steel tubes used for the purpose of exchanging the heat between the inside and the outside of tubes at exceptionally low temperatures of freezing point or under, such as heat exchanger tubes and condenser tubes (hereafter referred to as tubes).
This Standard is generally applicable to thetubes of 15.9 mm to 50.8 mm in outside diameter
NOTE 1 Austenitic stainless steel tubes specified in JIS G 3463 may be used as the steel heat exchanger tubes for low temperature service.
NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 9329-3 : 1997 Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 3 : Unalloyed and alloyed steels with specified low temperature properties
ISO 9330-3 : 1997 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 (Overall evaluation: MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEe Guide 21-1.
