High Light ASTM A312 TP304H serrated finned tubesTP304H stainless steel finned tubesserrated finned tubes for heat exchangers
ASTM A312 TP304H Serrated Finned Tubes

ASTM A312 TP304H Serrated Finned Tubes are engineered heat transfer components designed for demanding thermal applications involving elevated temperatures and continuous service conditions. Manufactured from TP304H austenitic stainless steel tubes, these finned tubes combine excellent oxidation resistance, high-temperature strength, and superior heat transfer efficiency.

The serrated fin design increases turbulence within the airflow, continuously disrupting the boundary layer and significantly improving convective heat transfer performance compared with solid fin configurations. This makes TP304H serrated finned tubes particularly suitable for boilers, economizers, waste heat recovery units, air-cooled heat exchangers, flue gas systems, and petrochemical process equipment.

Our serrated finned tubes are manufactured under strict quality control procedures and can be customized according to client specifications, international standards, and project requirements.

Product Features
Enhanced Heat Transfer Efficiency

The serrated fin structure creates additional turbulence around the fin surface, improving heat transfer coefficients and maximizing thermal performance.

Excellent High-Temperature Resistance

TP304H contains a higher carbon content than standard 304 stainless steel, providing improved creep strength and elevated-temperature mechanical properties.

Superior Oxidation Resistance

Suitable for continuous operation in oxidizing environments commonly found in power generation and petrochemical facilities.

Extended Service Life

High-quality welding processes and corrosion-resistant materials ensure long-term reliability and reduced maintenance costs.

Wide Application Compatibility

Suitable for gas-to-air, gas-to-liquid, and liquid-to-gas heat exchange systems operating under high-temperature conditions.

Typical Applications
  • Air Cooled Heat Exchangers (ACHE)
  • Waste Heat Recovery Systems
  • Economizers
  • Boiler Heat Recovery Units
  • Flue Gas Heat Exchangers
  • Petrochemical Processing Equipment
  • Refinery Furnaces
  • Thermal Power Plants
  • Heat Recovery Steam Generators (HRSG)
  • Industrial Drying Systems
Manufacturing Process

The serrated fin strip is continuously helically wound onto the TP304H base tube and permanently bonded through high-frequency resistance welding. This process creates a strong metallurgical bond between fin and tube, ensuring efficient thermal conductivity and mechanical integrity.

Manufacturing stages include:

  1. Raw material inspection
  2. Tube preparation
  3. Fin strip forming and serration
  4. High-frequency welding
  5. Dimensional inspection
  6. Non-destructive testing
  7. Surface cleaning
  8. Final quality verification
  9. Packing and shipment
