ASTM A213 TP304 Serrated Finned Tubes for Waste Heat Recovery Boilers

ASTM A213 TP304 Serrated Finned Tubes for Waste Heat Recovery Boilers are designed to improve heat transfer in industrial exhaust gas recovery systems. Manufactured with TP304 stainless steel base tubes and serrated fins configured to meet project requirements, these tubes provide an extended heat transfer surface for recovering thermal energy from hot flue gas and other process exhaust streams.

The serrated fin structure introduces repeated interruptions along the fin edges, helping disturb the gas-side boundary layer and promote heat transfer under suitable operating conditions. This design is particularly relevant to waste heat recovery boilers where gas-side heat transfer, available installation space, and pressure drop must be considered together.

The TP304 stainless steel base tube offers good resistance to general corrosion and good fabrication performance in suitable operating environments. Tube dimensions, fin material, fin geometry, and fin attachment requirements can be specified according to the equipment design and project requirements. Each supply can be manufactured and inspected against the agreed technical specification, with material traceability and quality documentation provided as required.

For boiler manufacturers and heat recovery system integrators, these serrated finned tubes offer a configurable solution for improving heat recovery performance while meeting project-specific material, dimensional, and inspection requirements.

ASTM A213 TP304 serrated finned tubes are intended for waste heat recovery boiler applications where thermal energy from industrial exhaust gas can be transferred to a working fluid through an extended heat transfer surface.

Typical application scenarios include:

• Industrial exhaust heat recovery: Recovering useful heat from suitable high-temperature exhaust streams generated by industrial processes.

• Gas-side heat transfer enhancement: Increasing the available external heat transfer area and promoting gas-side flow disturbance through serrated fin geometry.

• Compact heat exchanger design: Supporting boiler designers in balancing heat transfer requirements with tube bundle dimensions, gas flow resistance, and installation space.

• Corrosion-conscious material selection: Providing a TP304 stainless steel base tube option for operating environments compatible with its corrosion resistance.

The suitability of TP304 serrated finned tubes depends on the exhaust gas composition, operating and design temperatures, pressure, condensate formation, and the selected fin material. Chloride-containing environments, acidic condensates, and other aggressive media require specific corrosion assessment before material selection.
