This Japanese Industrial Standard specifies seamless nickel-chromium -iron alloy tubes (hereafter referred to as tubes) to be used, for example for heat exchangers or condensers in chemical and petroleum industries, and steam generators in nuclear industry, where the tube is designed for exchanging heat between inside and outside of its body. However, this Standard is not applicable to steel tubes for fired heater 1).
The supplementary quality requirements and U-bend tubes, which can be specified by the purchaser upon the agreement with the manufacturer, are specified in Annex A and Annex B, respectively.
Note 1) Steel tubes for fired heaters are specified in JIS G 3467.
