Products Description
Carbon steel boiler tubes are steel tubes suitable for high-pressure boilers. They are made of carbon steel or alloy steel and are resistant to high temperature and high pressure environments.
Role And Advantages Of Boiler Tubes
1. It is a thick-walled steel pipe with very good mechanical processing performance
2. It has good corrosion resistance and can resist the erosion of various chemical media
3. Seamless boiler tubes can maintain stable mechanical and chemical properties under high temperature environment and have excellent high temperature resistance
4. It has high compressive strength and impact resistance and can withstand large pressure and impact loads
The Use And Function Of Carbon Steel Boiler Tubes
1. Widely used in power facilities and power generation industry, seamless boiler tubes are key components of power generation equipment, and their performance directly affects power generation efficiency and safety.
2. In the field of petrochemicals, they are mostly used to transport high-temperature and high-pressure oil and gas media, and their stability and reliability are very high.
3. Seamless boiler tubes have good pressure resistance and corrosion resistance, and are an important component of aerospace, shipbuilding and other fields.

Material |
Carbon steel (SA-210 Gr. A1/A2, for low-medium pressure); Alloy steel (SA-213 T11/T22/T91, for high temp/pressure); Stainless steel (304/316, for corrosive environments) |
|
Chemical Composition |
Carbon steel: C ≤0.35%, Mn 0.7-1.3%; Alloy steel (T22): Cr 2.1-2.3%, Mo 0.9-1.1%; Stainless steel (304): Cr 18-20%, Ni 8-10.5% (key elements for heat/corrosion resistance) |
|
Mechanical Properties |
Tensile Strength: Carbon steel ≥415 MPa; Alloy steel (T91) ≥585 MPa; Stainless steel ≥515 MPa |
|
Heat & Corrosion Resistance |
Carbon steel: ≤450°C, resists mild oxidation; Alloy steel (T91): up to 650°C, good creep resistance; Stainless steel: up to 800°C, excellent in corrosive steam/gases |
|
Temperature Range |
Service: -20°C to 800°C (varies by material); carbon steel limited above 450°C (oxidation risk); alloy/stainless steel for high-temp critical sections |
|
Form & Dimensions |
Type: Seamless (high pressure, superheaters); welded (lower pressure, water walls) |
|
Standards Compliance |
ASTM (SA-178, SA-210, SA-213); ASME Section I (power boilers); DIN 17175 (European); JIS G3461 (Japanese industrial boilers) |
|
Fabrication |
Seamless: Hot-rolled/extruded (no welds, high pressure); Welded: ERW/TIG (cost-effective for non-critical areas) |
|
Key Applications |
Power plants: Superheaters, reheaters, water walls, economizers |
|
Key Advantages |
Carbon steel: Cost-effective for low-medium pressure; Alloy steel: High strength at extreme temps; Stainless steel: Resists corrosion in aggressive steam |
