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

Key Features

  • High Pressure Capability: Engineered for safe operation under high internal pressures.

  • Excellent Toughness: Good impact resistance and ductility at room temperature and elevated service temperatures.

  • Uniform Quality: Seamless manufacturing ensures consistent wall thickness and minimal defects.

  • Corrosion Resistance: Basic resistance to general corrosion; can be coated or lined for more aggressive environments.

Applicable Standards

  • JIS G3454: Carbon Steel Tubes for Pressure Service (Japan)

  • ASTM A106/A53: Seamless Carbon Steel Pipes for High-Temperature Service (USA)

  • GB/T 8163: Seamless Steel Tubes for Fluid Transportation (China)

  • EN 10305-1: Seamless Cold-Drawn Steel Tubes (Europe)

Application Fields

Carbon steel seamless pipes of the STPG 370 grade are widely employed in industries where durable, high-pressure tubing is essential. Typical applications include:

  • Oil & Gas: High-pressure conveyance lines, wellhead assemblies.

  • Power Generation: Boiler tubes, superheater assemblies.

  • Chemical Processing: Reactor feed lines, pressure vessels.

  • Petrochemical: High-temperature process piping, hydrocarbon transport.

  • Water & Steam: High-pressure water pipes, district heating systems.
