ASTM A192 Seamless Carbon Steel Boiler Tubes for High Pressure

ASTM A192 Seamless Carbon Steel Boiler Tubes: High-Temp & Pressure Resistant for Industrial Boilers

Product Introduction: ASTM A192 Seamless Carbon Steel Boiler Tubes

1. Material & Chemical Composition

Our ASTM A192 seamless carbon steel boiler tubes are crafted from high-purity carbon steel, engineered to withstand extreme thermal and pressure conditions. Their chemical composition adheres strictly to ASTM A192 standards:
ElementContent (%)
Carbon (C)0.25-0.35%
Manganese (Mn)0.60-0.90%
Phosphorus (P)≤0.035%
Sulfur (S)≤0.035%

​3. Mechanical Properties​

PropertyValue
Tensile Strength≥415 MPa
Yield Strength≥250 MPa
Elongation≥30%
Maximum Operating Temp450℃(842℉)

3. Equivalent Materials & Standards

For global compatibility, our ASTM A192 tubes align with these international equivalents:
StandardMaterial GradeRegion
ASTM A192Seamless Carbon SteelUSA
DIN 17175St35.8Europe
JIS G3461STB 35Japan
GB 308720GChina

4. Processing Technology

Manufactured via a precision seamless process:
  1. Hot Rolling: Solid billets are heated and pierced to form hollow shells, ensuring uniform wall thickness.
  2. Cold Drawing: Optional cold finishing for tight dimensional tolerances (±0.5% on diameter).
  3. Heat Treatment: Normalized and annealed to relieve internal stress, enhancing toughness.
  4. Non-Destructive Testing: 100% ultrasonic inspection and hydrostatic testing (at 30% higher than working pressure) to guarantee integrity.

5. Application Scenarios

Ideal for high-temperature, high-pressure boiler systems in:
  • Power generation (thermal power plants, biomass boilers)
  • Industrial boilers (chemical processing, refineries)
  • Heating systems (district heating, large-scale commercial boilers)

6. Product Advantages

Seamless Design: Eliminates weak points, reducing leak risks in high-pressure environments.
High-Temp Resistance: Stable performance at up to 450°C, avoiding deformation under thermal stress.
Cost-Effective: Carbon steel offers excellent strength-to-cost ratio for industrial applications.
Global Compatibility: Complies with ASTM A192 and equivalents, easing international project approvals.

7. FAQ

Q1: Can these tubes be customized for specific lengths?
A: Yes, we offer cut-to-length services (1-12m) with precision end finishing (beveled, plain) per project requirements.
Q2: Are they suitable for corrosive boiler environments?
A: For mild corrosion, they perform well. For aggressive media (e.g., chloride-rich water), contact us for coated or alloy alternatives.
Q3: What certifications do you provide?
A: All tubes come with ASTM A192 certification, mill test reports (MTR), and optional ISO 9001/ASME stamps.
