Stainless Steel Seamless Pipe ASTM A312 TP304H Serrated Fin Tube For Furnace

Stainless Steel Seamless Pipe, ASTM A312 TP304H, Serrated Fin Tube, For Furnace Tube

Product Introduction

The ASTM A312 TP304H Stainless Steel Serrated Fin Tube is a high-efficiency heat transfer component manufactured by attaching serrated stainless steel fins onto a TP304H seamless base tube through high-frequency welding (HFW). The serrated design significantly increases the surface area and enhances turbulence in gas flow, making it suitable for furnace tube convection sections where high-temperature and fouling resistance are critical.

Chemical Composition – ASTM A312 TP304H

Mechanical Properties

Key Advantages

• High-Temperature Stability
  TP304H is designed for elevated-temperature environments such as furnace convection zones.

• Serrated Fin Efficiency
  Serrated fins create micro-turbulence, enhancing heat transfer while reducing ash or soot buildup.

• Corrosion & Oxidation Resistance
  With excellent chromium and nickel content, TP304H resists oxidation and carburization in high-temperature gas streams.

• Easy Maintenance
  The serrated design helps reduce fouling and simplifies cleaning in harsh furnace atmospheres.

Applications

Primarily used in furnace tube convection sections in:

• Refinery Process Heaters

• Steam Reformers

• Fired Heaters

• Crude Oil Units

• Waste Heat Recovery Units

• Power Generation Furnaces

Position: Installed in the convection section of the furnace where flue gas flows across the finned tubes, transferring heat to internal fluids like steam, process oil, or feed gas.
