Our Serrated Finned Tubes for HRSG Harp Modules are engineered to deliver exceptional heat transfer efficiency and long-term reliability in demanding combined cycle power generation environments. Manufactured from premium ASME SA213 T22 alloy steel, these finned tubes are specifically designed for use in Heat Recovery Steam Generator (HRSG) harp assemblies where elevated temperatures, cyclic operation, and corrosive flue gas conditions require superior metallurgical performance.
The serrated fin configuration enhances turbulence within the gas stream, reducing the thermal boundary layer and significantly improving heat transfer efficiency compared with plain fin designs. This optimized geometry enables compact module construction while maximizing energy recovery from exhaust gases.
Designed to meet stringent industry requirements, our serrated finned tubes undergo comprehensive quality control procedures to ensure dimensional accuracy, metallurgical integrity, and dependable service performance throughout the operational life of the HRSG system.
Serrated finned tubes manufactured from SA213 T22 are widely used in:
The following dimensions represent common manufacturing capabilities. Customized configurations can be supplied upon request.
| Parameter | Typical Range |
|---|---|
| Outside Diameter (OD) | 31.8 mm to 63.5 mm |
| Wall Thickness | 2.6 mm to 8.0 mm |
| Tube Length | Up to 25,000 mm |
| Material Grade | ASME SA213 T22 |
| Manufacturing Process | Seamless |
| Parameter | Typical Range |
| Fin Height | 9 mm to 25 mm |
| Fin Thickness | 0.8 mm to 2.0 mm |
| Fin Pitch | 4 FPI to 12 FPI |
| Fin Material | Carbon Steel or Alloy Steel |
| Fin Type | Helical Serrated |
| Welding Method | High-Frequency Resistance Welding |
ASME SA213 T22 is a chromium-molybdenum alloy steel developed for elevated temperature service. The alloy offers an excellent balance of strength, oxidation resistance, creep resistance, and weldability, making it a preferred choice for HRSG tubing applications.
