The Integral High Finned Tube is formed by heating and extruding a billet tube. The wall thickness of the billet tube is determined by the height of the fins. It has advantages of high production efficiency, low cost. In addition, the fin roots of the integral finned tube are formed as a small radius arc for smooth transition which helps a better heat transfer.
The Integral Low Finned Tube fins are rolled out from the wall of the tubes and hence are integral with the tube. As the fins are formed from the base tube by rolling out material from its wall, the wall thickness under the finned section is reduced compared to the wall thickness at plain ends.
