Product Description

Stud Finned Tube: Advanced Heat Exchange Solutions for Global Industries

Stud Finned Tubes, also known as nail head finned tubes, are at the forefront of innovation in the heat exchange industry. With their unique design and superior functionality, they are engineered to meet the demanding needs of various industrial applications, from petrochemical refineries to power plants.

Innovative Design and Construction

The Stud Finned Tube is characterized by its unique structure, where cylindrical pins are welded in a square or hexagonal pattern onto the surface of the heat exchange tube. This design ensures a compact, yet highly effective heat transfer solution. The arrangement and welding process create a robust mechanical bond, capable of withstanding extreme mechanical loads and stresses typically encountered during operational and cleaning processes.

The pins, or "studs," made from either carbon steel, stainless steel, or Cr-Mo alloy, are welded to the tube using an Electrical Resistance Process. This method ensures a strong, reliable bond that enhances heat transfer efficiency while maintaining structural integrity. The mechanical pressing of studs during welding further strengthens the bond, making these tubes ideal for high-pressure and high-temperature environments.

Exceptional Performance and Efficiency

One of the standout features of Stud Finned Tubes is their exceptional heat transfer efficiency and self-cleaning capabilities. The cantilever structure of the pin ribs vibrates under airflow, preventing soot accumulation and facilitating strong turbulent scouring by flue gases. This results in superior heat exchange performance and prolonged operational life due to reduced maintenance needs.

Versatile Applications

Stud Finned Tubes thrive in diverse applications, including economizers, boilers, heat exchangers, tube bundles, radiators, air coolers, and air preheaters. Their robust design makes them suitable for use in compact waste heat boilers, oil-fired and gas-fired boilers, and oil heaters. The versatility extends to materials, with base tubes made from stainless steel, carbon steel, and alloy steel, and a range of material grades such as A335 P1, P5, P9, P11, and A213 T9, T11, T22, among others.
