There are many different types and methods of fin-to-tube attachment. Cain Industries has accumulated years of experience in the field of waste heat recovery from our industrial combustion exhaust product lines. These product lines include boiler economizers, waste heat recovery silencers, and packaged waste heat boilers – which all utilize finned tubing under rigorous thermal load conditions.
We have determined which specific types of finned tubing can best withstand the extremes of temperature and environment in our customers’ installations. As a result we have developed proprietary technology to produce a range of industrial grade products that meet the industry’s stringent demands.
When you have a finned tube requirement, we will offer the best recommendation to suit your need at competitive pricing. We’ll quote your specification or create a specification based on your exact needs. We can offer basic finned tubing in straight lengths or subassemblies, or a complete heat exchanger.

ASME Quality Control: ASME stamping is available to meet Sec.VIII Div.l (‘U’ symbol) and Sec.l (‘S’ symbol) and National Board Stamp.

Sample Designs: Cain Industries will provide prototype finned tubing or assemblies, when required, at a nominal cost.

Optional protection:
• A Nickel Clad Coating, up to 2 mil thickness, is available to provide extended corrosion protection.

The Exclusive Al-Fuse™ Bonding Process
Cain Industries’ proprietary metal bonding process called Al-Fuse™ produces a permanent metallurgical bond between the dissimilar metals. One very popular type is Aluminum fin bonded to Stainless steel tube which assures the original performance at the rated capacity of the spiral finned surface during its lifetime.
Cain’s proprietary process incorporates a liquid composition which, when subjected to heat, creates a reaction causing alloying of the metals. The result is an integral one-piece unit possessing maximum heat transfer capability and a protective coating offering high resistance to corrosion.

Sample Applications:

Converter Cooler
With spiral fin tube across the face of the radiator, the engine-powered fan cools the engine’s jacket water as well as cooling hot oil circulated through the finned tubing.

Custom Designed Radiator
Straight lengths of spiral fin tubing fitted into top and bottom tanks provide cooling for a closed system. Additional cooling is possible with a power-driven fan.

Air Compressor
Two short lengths of spiral finned tubing provide the surface required to cool compressor air.

Hydraulic Power Supply
Life of power source is lengthened by removing excess heat from hydraulic fluid used with machine tools. Hot fluid is cooled as it circulates through spiral fin tube placed in the path of the engine’s combustion air supply.

PRODUCT APPLICATION:
Cain industrial spiral finned tubing can be custom
fabricated to suit your specific needs - both in
metal specification and in the shape of the
formed sections. Cain Industries can provide
basic finned tubing in straight lengths or
subassemblies, or a complete heat exchanger.
