| High Light | ASTM A312 TP304H finned tube ，High frequency welded fin tube ，Air preheater solid fin tube | ||
ASTM A312 TP304H High Frequency Welded Finned Tubes are engineered for air preheater applications operating under elevated temperatures and demanding industrial conditions. Manufactured using high-frequency resistance welding technology, the steel fins are continuously welded to the TP304H stainless steel base tube, providing excellent heat transfer efficiency, reliable fin bonding, and long-term structural stability.
ASTM A312 TP304H is a high-carbon version of Type 304 stainless steel specifically developed for elevated-temperature service. Its enhanced creep strength and oxidation resistance make it particularly suitable for heat recovery systems where prolonged exposure to temperatures above 500°C is common.
These finned tubes are widely used in power generation, petrochemical processing, industrial furnaces, and waste heat recovery systems requiring efficient air heating and energy conservation.
ASTM A312 TP304H High Frequency Welded Finned Tubes are commonly used in:
| Item | Standard Range |

| Base Tube Outside Diameter | 19.05 mm – 63.5 mm (3/4" – 2-1/2") |
| Base Tube Wall Thickness | 2.0 mm – 8.0 mm |
| Tube Length | Up to 18,000 mm |
| Fin Height | 8 mm – 25 mm |
| Fin Thickness | 0.8 mm – 2.0 mm |
| Fin Pitch | 3 mm – 12 mm |
| Fin Material | Carbon Steel, Stainless Steel or Alloy Steel (according to service conditions) |
| Element | Content (%) |
