ASME SA106 Gr.B Seamless Carbon Steel Boiler Tube – High-Temperature & High-Pressure Resistance

1. Product Overview

ASME SA106 Gr.B Seamless Boiler Tubes are designed for high-temperature and high-pressure applications in boilers, heat exchangers, and power plants. Manufactured under ASTM A106/ASME SA106 standards, these tubes ensure durability, corrosion resistance, and excellent thermal conductivity.

2. Material & Chemical Composition

Material: Carbon steel (equivalent to China’s 20# steel).
Key Chemical Properties:

Element	Content (%)
Carbon (C)	≤0.30
Manganese (Mn)	0.29–1.06
Phosphorus (P)	≤0.025
Sulfur (S)	≤0.025
Silicon (Si)	≥0.10

3. Mechanical Properties

Property	Value
Tensile Strength	≥415 MPa
Yield Strength	≥240 MPa
Elongation	≥12%
Hardness	≤197 HB

4. Key Features & Advantages

High-Temperature Resistance: Suitable for -29°C to 565°C environments .
Seamless Design: No welds, ensuring leak-proof performance under pressure.
Easy to Weld & Fabricate: Low carbon content minimizes post-weld brittleness.
Certified Quality: Complies with ASME, ASTM, and EN standards.

5. Applications

Boilers: Superheaters, reheaters, and steam pipelines.
Oil & Gas: Refinery pipelines, heat exchangers.
Power Plants: High-pressure fluid transport.

6. FAQ

Q: What’s the difference between SA106 Gr.B and 20G tubes?
A: SA106 Gr.B has higher Mn content (0.29–1.06%) vs. 20G (0.35–0.65%), offering better strength at elevated temperatures.

Q: Do you provide custom sizes?
A: Yes! We support OD: 10–1200mm, thickness: 1–50mm, and lengths up to 18m.
