Fins & corrugations
Tube finning is a cold forming process for generating fins on tubes.
A specific technology with 3 or 4 shafts assembled with disks is used for cold forming the tubes.
The finned tubes are primarily dedicated to heat exchangers. The fins ease the heat exchange between internal circulating fluid and the outside.
Finned tubes are dedicated to heat exchangers used in many industries e.g. power generation, heaters, etc.
Different types and material of tubes can be cold formed like stainless steel, copper, aluminium, etc. and with high or low fins.
