ASTM A376 TP347H Stainless Steel Seamless Tube HFW Fin Tube For Convection Coil

ASTM A376 TP347H, Stainless Steel Seamless Tube, HFW Fin Tube, For Convection Coil Tube

Introduction

Yuhong Holding Group has been exporting goods like heat exchanger tube, boiler tube, fin tube to all over the world. We can provide the all kinds of tube like stainless steel, carbon steel, alloy steel, nickel alloy steel... HFW fin tube is what we are specialized in. Equipped with 10 production lines, we can provide hundreds and thousands tons of fin tube.

The ASTM A376 TP347H HFW fin tube combines a seamless stainless steel core with high-frequency welded (HFW) fins, designed for convection coils in fired heaters, boilers, and power plants. TP347H stainless steel offers excellent resistance to creep, stress corrosion, and high-temperature oxidation, making it a premium choice in critical heat transfer zones.

Chemical Composition of TP347H (Tube Material)

Mechanical Properties (TP347H)

Advantages of Solid Fin Tube

• High Temperature Resistance
  Performs reliably under sustained high heat in convection zones.

• Excellent Oxidation and Creep Resistance
  Niobium stabilization minimizes grain boundary failure.

• Efficient Heat Transfer
  Fin-to-tube bonding via HFW enhances thermal performance with high mechanical strength.

• Durability in Corrosive Environments
  Suitable for aggressive flue gas compositions and steam applications.

Applications of HFW Fin Tube

The tube is used in the convection section of:

• Fired Heaters
  (hydrocarbon processing, refinery units)

• Power Boilers & Steam Generators

• Steam Superheaters & Reheaters

• Waste Heat Recovery Units

Installation Location:
Located above the radiant section in fired heaters, where gases have cooled slightly and convection heat transfer dominates.
