JIS G3454 is Janpness standard for Carbon steel pipe for pressure service.  JIS G3454是壓力用碳鋼管的韌性標準。

Scope範圍

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).

本標準規定了在350°C或更低溫度下用於高壓服務的碳鋼管（以下簡稱“管道”）。本標準一般適用於外徑10.5mm（公稱直徑6A或1/8B）至660.4mm（公名直徑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.

除本文規定的項目外，買方可以在與製造商達成協議後預先指定特殊的質量要求，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是日本工業標準，規定了最高溫度約為350°C的高壓用碳鋼管。該標準涵蓋了外徑為15至600毫米、壁厚為1至50毫米的管道。JIS G3455規範包括四種不同等級的碳鋼管：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.

管子應采用無縫工藝、電阻焊工藝或對接焊工藝製造，其他等級的管子應采用無接縫工藝或電阻焊工藝製造。管子應為製造狀態或冷加工狀態，否則應進行適當的熱處理。

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.

管子應幾乎筆直。兩端應與管子軸線成直角。管子應無不利於實際使用的缺陷。
