These carbon steel pipes are designed to withstand high-pressure and high-temperature conditions.
These carbon steel pipes are designed to withstand high-pressure and high-temperature conditions, making them suitable for use in applications such as steam boilers, pipelines, and high-pressure equipment. The pipes are manufactured through a seamless process or a welded process, depending on the requirements of the application.
The mechanical properties of JIS G3455 carbon steel pipes vary depending on the grade. For example, STS 370 has a minimum tensile strength of 370 MPa and a minimum yield strength of 215 MPa, while STS 510 has a minimum tensile strength of 510 MPa and a minimum yield strength of 335 MPa.
This Standard specifies the carbon steel pipes (hereafter referred to as “pipes”) used for high pressure service at temperatures 350°C or lower. This Standard is generally applicable to pipes of outside diameters 10.5mm (nominal diameter 6A or 1/8B) to 660.4 mm (nominal diameter 650A or 26B).
In addition to the items specified in this text, the purchaser can previously designate special quality requirements upon agreement with the manufacturer, which are shown in Annex JA.
NOTE: The International Standard 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)
The 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/IEe Guide 21-1.
JIS G3455 is a Japanese Industrial Standard that specifies carbon steel pipes for high pressure service at an approximate maximum temperature of 350°C. The standard covers pipes with an outer diameter ranging from 15 to 600 mm, and wall thicknesses from 1 to 50 mm. The JIS G3455 specification includes four different grades of carbon steel pipes: STS 370, STS 410, STS 480, and STS 510.

The tubes shall be manufactured by seamless process, electric resistance welding process, or butt welding process, and those of other grades shall be manufactured by seamless process or electric resistance welding process. The tube shall be as manufactured or as cold-finished condition, or they shall be subjected to appropriate heat treatment.
The tubes shall be practically straight. and the two ends shall be at right angles to the axis of the tube. The tubes shall be free from defects detrimental to practical use.
The following standards contain provisions which, through reference in this text, constitute provisions of this Standard. The most recent editions of the standards (including amendments) indicated below shall be applied.
