ASTM A192 Seamless Carbon Steel Boiler Tubes: High-Temp & Pressure Resistant for Industrial Boilers
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:
| Element | Content (%) |
| Carbon (C) | 0.25-0.35% |
| Manganese (Mn) | 0.60-0.90% |
| Phosphorus (P) | ≤0.035% |
| Sulfur (S) | ≤0.035% |
3. Mechanical Properties
| Property | Value |
| Tensile Strength | ≥415 MPa |
| Yield Strength | ≥250 MPa |
| Elongation | ≥30% |
| Maximum Operating Temp | 450℃(842℉) |
For global compatibility, our ASTM A192 tubes align with these international equivalents:
| Standard | Material Grade | Region |
| ASTM A192 | Seamless Carbon Steel | USA |
| DIN 17175 | St35.8 | Europe |
| JIS G3461 | STB 35 | Japan |
| GB 3087 | 20G | China |
Manufactured via a precision seamless process:
- Hot Rolling: Solid billets are heated and pierced to form hollow shells, ensuring uniform wall thickness.
- Cold Drawing: Optional cold finishing for tight dimensional tolerances (±0.5% on diameter).
- Heat Treatment: Normalized and annealed to relieve internal stress, enhancing toughness.
- Non-Destructive Testing: 100% ultrasonic inspection and hydrostatic testing (at 30% higher than working pressure) to guarantee integrity.
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)
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.
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.
