Product Description

Product Description

1. Standard Compliance

• Primary Standard: JIS G3459 (Carbon Steel Pipes for High-Temperature Service)

• Complementary Standards:

  • JIS B2301 (Steel Pipe Fittings)

  • ASME B36.10M (Dimensional Compatibility)

  • ISO 9330-2 (International Equivalent)

2. Dimensional Specifications

Parameter	Tolerance
OD Tolerance	±1.0% (Hot-Finished)
WT Tolerance	+15%, -10%
Straightness	≤0.2% of Length

3. Performance Advantages

 High-Temperature Strength - Retains structural integrity up to 350°C
 Weldability - Low carbon content (C ≤0.30%) enables easy welding
 Cost-Effective - More economical than alloy steels for moderate temp services

4. Quality Assurance

• Chemical Composition (STPG370):

Element	Requirement
C	≤0.30%
Mn	≤1.20%
P	≤0.040%
S	≤0.040%
