ASTM A213 T12 Alloy Steel Solid Fin Tube with Carbon Steel Fin Strip for Economizer
This product is a high-performance heat transfer component designed for use in industrial economizers, particularly in power plants, boilers, and waste heat recovery systems. The base tube is manufactured from ASTM A213 T12 alloy steel, known for its excellent high-temperature strength, oxidation resistance, and durability under thermal cycling conditions. This makes it ideal for prolonged operation in environments where steam or flue gas temperatures are elevated.
The fin structure is solid type, meaning the carbon steel fin strip is helically wound and continuously welded to the tube's outer surface. The carbon steel fin strip offers a balance of mechanical strength, thermal conductivity, and cost-effectiveness. Solid fins provide robust protection against erosion and corrosion from flue gas particles, as well as enhanced surface area for improved heat transfer efficiency.
Chemical Composition — ASTM A213 T12 (Base Tube)
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.05–0.15 |
| Manganese (Mn) | 0.30–0.61 |
| Phosphorus (P) | ≤ 0.025 |
| Sulfur (S) | ≤ 0.025 |
| Silicon (Si) | 0.50–1.00 |
| Chromium (Cr) | 0.80–1.25 |
| Molybdenum (Mo) | 0.44–0.65 |
Mechanical Properties — ASTM A213 T12 (Base Tube)
| Property | Value |
|---|---|
| Tensile Strength | ≥ 415 MPa |
| Yield Strength | ≥ 220 MPa |
| Elongation (in 50 mm) | ≥ 30% |
| Hardness (HB) | ≤ 163 HB |
| High Temperature Strength | Excellent up to 550°C |
Advantages & Features:
-High thermal efficiency – Increased external surface area improves heat exchange between flue gases and the working fluid.
-Mechanical durability – Solid fin construction ensures excellent wear resistance, especially in abrasive gas flow environments.
-Temperature resilience – ASTM A213 T12 withstands high operating temperatures with minimal creep deformation.
-Corrosion resistance – Alloy steel base resists oxidation and sulfidation at high temperatures, extending service life.
Applications:
-Boiler economizers in thermal power plants.
-Waste heat recovery systems in petrochemical and refinery operations.
-Heat recovery steam generators (HRSG) in combined cycle power plants.
-Industrial heating systems where efficiency and durability are critical.
This combination of ASTM A213 T12 alloy steel tubing and carbon steel solid fins provides a cost-effective yet high-performance solution for demanding economizer applications, ensuring optimized heat recovery and long-term operational reliability.
