JIS G3454 STPG 370 Carbon Steel Seamless Pipes for Pressure Service

Material

JIS G3454 STPG 370 pipes are manufactured from low-carbon carbon steel specifically formulated for pressure service. These seamless tubes offer excellent strength and toughness at elevated temperatures—up to 350 °C—and are produced via hot-rolling or cold-drawing processes to ensure uniform microstructure and minimal defects

Specifications

Standard & Grade: JIS G3454 STPG 370
Outer Diameter: 13.7 – 914.4 mm (⅟₄ – 36 in)
Wall Thickness: 1.0 – 30 mm
Length: 1 – 12 m (or per customer requirement)
Manufacturing: Seamless (hot-rolled or cold-drawn)
Service Temperature: ≤ 350 °C
