ASTM A376 TP347H Stainless Steel Solid HF Welding Fin Tube For Convection Coil Tube

ASTM A376 TP347H Stainless Steel Solid Fin Tube, For Convection Coil Tube

Introduction

Yuhong is specializedin heat exchanger tube, fin tube, boiler tube. With experience of exporting fin tube for 12 years, Yuhong has already win the trust of client from over 80 cuntries. We can provide fin tube with all kinds of, such as G Type fin tube, extruded fin tube, Wound Fin tube, HFW fin tube, low fin tube.......

The ASTM A376 TP347H solid fin tube is designed for high-temperature heat transfer systems, especially in convection coil sections of boilers and furnaces. Made from seamless TP347H stainless steel, the tube is externally finned using solid carbon steel or stainless steel strips bonded by high-frequency welding (HFW), significantly improving heat exchange efficiency in compact designs.

Chemical Composition (TP347H Tube)

Mechanical Properties

Advantages

• High Temperature Strength
  Stabilized with niobium (Nb) for superior creep resistance at elevated temperatures.

• Enhanced Heat Transfer
  Solid fins provide greater surface area for efficient heat dissipation in convection zones.

• High Welding Integrity
  High-frequency welding delivers tight fin-to-tube bonding, even under thermal cycling.

• Corrosion and Oxidation Resistant
  Excellent resistance to scaling and corrosion in flue gas environments.

• Long Service Life
  Durable construction ideal for continuous-duty, high-heat applications.

Applications

Used primarily in the convection section of:

• Fired Heaters (Oil & Gas)

• Industrial Furnaces

• Power Plant Boilers

• Heat Recovery Units

• Steam Superheaters

These tubes are installed horizontally or vertically where they absorb convective heat from flue gases after the radiant zone.
