JIS G3454 is Janpness standard for Carbon steel pipe for pressure service.  JIS G3454是压力用碳钢管的韧性标准。

Scope范围

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).

本标准规定了在350°C或更低温度下用于高压服务的碳钢管（以下简称“管道”）。本标准一般适用于外径10.5mm（公称直径6A或1/8B）至660.4mm（公名直径650A或26B）的管道。

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.

除本文规定的项目外，买方可以在与制造商达成协议后预先指定特殊的质量要求，如附件JA所示。

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.

JIS G3455是日本工业标准，规定了最高温度约为350°C的高压用碳钢管。该标准涵盖了外径为15至600毫米、壁厚为1至50毫米的管道。JIS G3455规范包括四种不同等级的碳钢管：STS 370、STS 410、STS 480和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.

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。
