JIS G3458 STPA12 STPA20 STPA22 STPA23 STPA24 Alloy Steel Pipe For Boiler
Introduction
JIS G3458 is a Japanese Industrial Standard that specifies the requirements for alloy steel pipes used in high-temperature and high-pressure applications. The STPA series, including STPA12, STPA20, STPA22, STPA23, and STPA24, are chromium-molybdenum alloy steel pipes designed for use in various industries, including power generation, petrochemical, and oil and gas.
Material and Specification
The STPA series pipes are made from high-quality chromium-molybdenum alloy steel, which provides excellent mechanical properties and resistance to high temperatures and pressures. These pipes are typically used in applications where strength and durability are critical.
Key Features
- High Strength: Designed to withstand high pressure and temperature.
- Corrosion Resistance: Chromium and molybdenum enhance corrosion resistance.
- Weldability: Suitable for welding and fabrication.
- Versatility: Applicable in various industries, including energy and chemical processing.

Steel Grade
The STPA series is categorized under chromium-molybdenum alloy steels, which are known for their high strength and toughness. Each grade has specific properties that make it suitable for different applications.
Application
The JIS G3458 STPA series pipes are widely used in:
- Power Plants: For steam and gas pipelines.
- Petrochemical Industry: In the transportation of chemicals and hydrocarbons.
- Oil and Gas: For high-pressure pipelines and equipment.
Possible Alternative Grades
While the STPA series is widely used, there are alternative grades that may be considered based on specific requirements:
- ASTM A335 P11/P22: Similar chromium-molybdenum alloy steel pipes.
- EN 10216-2 16Mo3: European equivalent for high-temperature applications.
- ASME SA335 P5: Another alternative for high-temperature service.
