Product Description
Low Fin (Integral) tubing is a type of extruded tubing that consists of small low fins. The low fin tube is very similar to the extruded "high fin" types but these tubes have the same diameter as the base tube. Low Fin Enhanced tubes can be used in standard shell and tube baffles and tube sheets. The primary advantage for the low fin tube is providing surface enhancement and better heat transfer over smooth tubing.
During the manufacturing process, fin material is tightly wound around the outside of the tube to secure metals-to-metal contact of the base of the fin with the tube.
Integral Low Fin Tube has the advantage that it can improve the thermal performance of a Heat Exchanger without the necessity for changing shell size, flow arrangement or the repositioning of piping. The external surface of the tube is increased by the formation of "low fins" by direct extrusion from the material of the base tube.
Advantage
Fine-Fin® provides 2.5 to 3 times the external surface area of bare tube
This yields numerous benefits for the heat transfer equipment
Reduced capital cost for new equipment
Enhanced heat exchange efficiency means less Fine-Fin tubing is required to accomplish the same heat transfer as a bare tube.
Reduced retrofitting cost for existing equipment
Fine-Fin can increase the performance of an existing heat exchanger without the difficult and expensive task of building new shells, heads, nozzles, piping and foundations.
Space, weight & structural savings
Reduced plot space and weight can be extremely valuable in offshore production or high elevation distillation columns. Fine-Fin technology transforms large shell & tube exchangers into compact heat exchangers.
More materials & alloys to select
Fine-Fin is available in a wider range of alloys than traditional low-fin tubing which is restricted to soft metals. This opens a new world of opportunity for enhanced tubing in corrosive service. The more expensive the tube material, the more dramatic the cost savings of Fine-Fin.
Reduced maintenance & life cycle cost
Proper material selection with Fine-Fin can eliminate costly downtime & maintenance. Example: Coastal refineries using once-through seawater cooling systems can benefit by substituting conventional copper nickel tubing with Titanium Fine-Fin tubing. Titanium Fine-Fin is highly resistant to seawater corrosion erosion.
Application
The Integral low fin tubes are widely used in chemicalprocess. Especially applicable between air or other gases on the fin-side and a fluid on the tube-side.
When to Consider Integral low fin tube.
Shell side heat transfer is controlling.
Expensive materials of construction are required.
Debottlenecking an existing exchanger.
Retrofitting or upgrading with new tube material.
Meeting a stringent space or weight requirement.
