Advantages:
1.Optimal mechanical and thermal connection of the tube and the fins, integrally connected to the root wall
2.Suitable for expansion into tubesheets as plain ends remain soft
3.Equivalent simple assembly of the tubes into a shell and tube heat exchanger like a plain tube as fin tip diameter being equal to the plain end diameter
4.Suitable for U-bending for U-tube heat exchanger designs
Applications:
Boiling,Condensation,Single phase heat transfer
