Shoulder Tension Finned Tubes Manufacturer and Supplier in India
Shoulder Tension Finned Tubes consist of mechanically bonded heat exchanger tubes that are tightly wound with an L-shaped fin under controlled tension on the base tube for reliable thermal performance. This process establishes a stable and secure fin-to-tube contact without welding, thus reducing contact resistance and allowing for thermal expansion over the life of continuous use. They are usually highly effective at temperatures from 150°C to 200°C and can be made with carbon steel, stainless steel, copper, aluminium, titanium, and nickel alloy base tubes. Amardeep Steel is a trusted manufacturer and supplier
of Shoulder Tension Finned Tubes in India, which are precision-engineered in customized dimensions and material combinations to satisfy international quality standards for industrial heat exchange applications.

Frequently Asked Questions
1. What are Shoulder Tension Finned Tubes?
Shoulder Tension Finned Tubes are mechanically bonded heat exchanger tubes with L-shaped fins tightly wound around the base tube to improve heat transfer efficiency.
2. How do Shoulder Tension Finned Tubes improve heat transfer?
They increase the external surface area of the tube, allowing faster and more efficient heat transfer between the tube and the surrounding fluid.
3. Are Shoulder Tension Finned Tubes corrosion resistant?
Yes. They offer good corrosion resistance, especially when manufactured using stainless steel, copper, titanium, or other corrosion-resistant base tube materials.
4. Can Shoulder Tension Finned Tubes be customized?
Yes. They can be customized in terms of tube material, fin material, fin pitch, tube dimensions, fin height, and overall length to suit specific applications.
5. What base tube materials are available for Shoulder Tension Finned Tubes?
They are available with carbon steel, stainless steel, copper, aluminium, titanium, nickel alloys, Monel, Inconel, Hastelloy, Duplex, and Super Duplex base tubes.
