ASTM A376 TP347H Solid Fin Tube Alloy Steel Seamless Tube For Convection Coil Tube

Alloy Steel Seamless Tube ASTM A376 TP347H, Solid Fin Tube, For Convection Coil Tube

Product Introduction

The ASTM A376 TP347H Solid Fin Tube is made from high-temperature austenitic stainless steel (347H), designed for high-performance heat transfer in convection sections of furnaces and boilers. The solid fin is welded directly onto the tube surface using High Frequency Welding (HFW) or manual processes, creating a durable structure capable of operating under extreme thermal and corrosive conditions.

Chemical Composition – ASTM A376 TP347H

Mechanical Properties – TP347H

Advantages

• Excellent High-Temperature Strength
  Ideal for use in superheater and reheater tubes in power plants.

• Enhanced Creep Resistance
  Nb-stabilization makes 347H superior under prolonged high-heat exposure.

• Superior Corrosion & Oxidation Resistance
  Maintains integrity in flue gas environments with high sulfur content.

• Solid Fin Structure
  Provides mechanical durability, long service life, and efficient heat transfer.

• Weldable and Formable
  Supports complex U-bends and coil configurations for compact convection sections.

Applications

Mainly used in high-temperature heat recovery and energy conversion systems, such as:

• Furnace Convection Coils

• Power Plant Boilers

• Petrochemical Reheaters

• Waste Heat Recovery Units

• Refinery Heater Tubes
