We are dedicated to providing the finest products and services to meet the needs of our global partners.
One of our flagship offerings is the TP304H HFW Serrated Fin Tube, manufactured to ASTM A312 standards. This product is specifically designed for Heat Recovery Steam Generators (HRSG) systems, ensuring superior heat transfer efficiency and durability under high-temperature conditions.
Material Overview: TP304H Stainless Steel
TP304H is a high-carbon variation of TP304 stainless steel, offering enhanced strength and thermal stability at elevated temperatures. It is commonly used in high-pressure and high-temperature heat recovery systems, such as HRSG applications. Below is a comparison of TP304, TP304L, and TP304H materials:
| Property | TP304 | TP304L | TP304H |
|---|---|---|---|
| Carbon (C) Content | ≤ 0.08% | ≤ 0.03% | 0.04% - 0.10% |
| High-Temperature Strength | Medium | Low | High |
| Corrosion Resistance | Excellent | Excellent | Excellent |
| Weldability | Excellent | Superior (low C content avoids sensitization) | Good |
| Applications | General-purpose | Low-corrosion environments | High-temperature systems |
Key Benefits of TP304H
- High-Temperature Strength: The higher carbon content increases creep resistance, making it ideal for HRSG and other high-temperature applications.
- Corrosion Resistance: Retains excellent corrosion resistance consistent with TP304/L grades.
- Durability: Enhanced mechanical properties for long service life in demanding environments.
Serrated Fin Tube Overview
Serrated (or segmented) fin tubes are designed to maximize heat transfer efficiency by increasing the surface area exposed to the working fluid. These fins are manufactured using High-Frequency Welding (HFW) technology, ensuring a robust bond between the fins and the base tube.
Common Materials for Serrated Fins
- Carbon Steel: Cost-effective and suitable for non-corrosive environments.
- Stainless Steel (TP304, TP304H, TP316, etc.): Ideal for corrosive and high-temperature applications.
- Alloy Steel (T11, T22): Used in environments requiring higher creep resistance.
Applications of TP304H Serrated Fin Tubes
In HRSG Systems
- TP304H serrated fin tubes are widely used in Heat Recovery Steam Generators (HRSG) for waste heat recovery in power plants.
- These tubes efficiently transfer heat from exhaust gases to water/steam, improving overall energy efficiency and reducing fuel consumption.
Other Applications
- Petrochemical Industry: Process heaters and waste heat recovery units.
- Chemical Industry: Heat exchangers for corrosive fluids.
- Power Generation: Steam generators and air preheaters.
- Oil & Gas: Offshore platforms and refineries.
