Opis produktu
ASTM A312 TP304H Serrated Finned Tubes for Air Coolers
Product Overview

ASTM A312 TP304H Serrated Finned Tubes for Air Coolers are engineered for optimal thermal performance in industrial air-cooled heat exchangers. Designed with precision serrated fins on high-quality TP304H stainless steel tubes, these components maximize heat transfer efficiency while ensuring long-term corrosion and oxidation resistance under high-temperature and cyclic service conditions.

Ideal for petrochemical plants, refineries, power generation units, and chemical processing facilities, these tubes are widely used in air coolers, fin fan coolers, and process gas cooling systems. The serrated fin profile improves turbulence around the tube, increasing the overall heat transfer rate and minimizing fouling, which reduces maintenance requirements and operational costs.


Key Features
  • High-performance serrated fin design for superior heat transfer
  • Manufactured from ASTM A312 TP304H austenitic stainless steel tubes
  • Excellent corrosion and oxidation resistance at elevated temperatures
  • High creep strength suitable for continuous high-temperature operation
  • Customizable fin height, pitch, and density to meet thermal design needs
  • Available in high-frequency welded, resistance welded, or mechanically bonded options
  • Long service life with reduced fouling and maintenance

Typical Applications
  • Industrial Air Coolers
  • Fin Fan Heat Exchangers
  • Petrochemical Gas Cooling Systems
  • Power Plant Air-Cooled Condensers
  • Refineries and Process Cooling Units
  • Thermal Oxidizer Gas Coolers

Tube ends were clean, dimensions consistent. Our crew didn't run into fit-up issues.

No leaks, no fin damage, performance consistent. Heat transfer hasn't dropped, so fouling doesn't seem to be a problem yet.

For power plant boilers, especially in industrial settings like ours, these tubes work. Good heat transfer, holding up well.
