Crimped Finned Tube

 

Crimped Fin Tube (Spiral Tension wound Fin Tube):

The Crimped fin tubes also known as spirally tension wound finned tubes is a very widely used finned Tube type for a various number of applications.

As the name suggests the manufacturing of Crimped Finned Tube (Spiral Tension wound Fin Tube) is done by Tension winding of fin material on the base tube. The base tip of the fin strip is pre formed on a set of performing rollers.

This pre forming allows for a wider base and hence contact area is increased. It also enables more turbulence for the air flowing over the finned tube thereby increasing heat transfer efficiency. The ends of Fins are tag welded to secure its bond on the base.

This finning takes place on dedicated specially designed finning machines with auto feed mechanism. This process allows a very long length of tubes to be finned.

It finds application in various industries ranging from driers, radiators, heaters etc and are used in many industries like food, chemical, Oil Cooling etc.
