JIS G3456 is a Japanese Industrial Standard that specifies carbon steel pipes for high-temperature service.

JIS G3456是日本工业标准，规定了高温用碳钢管。

JIS G3456 standard was prepared based on ISO 9329-2:1997 and ISO 9330-2:1997 with some modifications of the technical requirements.

JIS G3456标准是根据ISO 9329-2:1997和ISO 9330-2:1997制定的，对技术要求进行了一些修改。

JIS G3456 applies to carbon steel pipes mainly used for piping at temperatures above 350℃. The pipes are available in various grades, including STPT370, STPT410, and STPT480, which have minimum yield strengths of 215 MPa, 245 MPa, and 315 MPa, respectively. The pipes can be manufactured using either a seamless or welded process.

The JIS G3456 standard was last updated in 2019 (JIS G3456:2019). The standard is protected by copyright and the full text can be accessed through the official website of the Japanese Standards Association.

JIS G3456标准最后一次更新是在2019年（JIS G3456:2019）。该标准受版权保护，全文可通过日本标准协会的官方网站访问。

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.

管子应采用无缝工艺、电阻焊工艺或对接焊工艺制造，其他等级的管子应采用无接缝工艺或电阻焊工艺制造。管子应为制造状态或冷加工状态，否则应进行适当的热处理。

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.

管子应几乎笔直。两端应与管子轴线成直角。管子应无不利于实际使用的缺陷。
