ASEA METAL mainly produces
JIS G3454 STPG 370-S tube at our Korean factory!
JIS G3454 STPG 370-S
is a high-quality seamless carbon steel pipe
designed for pressure piping services
at temperatures up to approximately 350°C. The "STPG 370" designation guarantees a minimum tensile strength of 370 MPa
, making it ideal for carrying water, oil, gas, steam, and air in various industrial plants and pipeline systems.
The "-S"
suffix indicates Seamless manufacturing
, ensuring excellent structural integrity, uniform wall thickness, and superior pressure resistance compared to welded alternatives.
Key Features
- Seamless Reliability:
Manufactured without a weld seam, offering maximum safety and performance under high-pressure conditions.
- Excellent Pressure & Temperature Resistance:
Optimized for stable operation in pressure systems at operating temperatures under 350°C.
- Global Standards Equivalent:
Closely matches ASTM A53 Grade A (Seamless)
in terms of chemical composition and mechanical properties.
