L / LL / KLM Type Finned Tubes

(Wrap Around Fin Tubes)

Anand Seamless Ltd. offers a wide range of Wrap Around Finned Tubes, commonly known as L-Type, LL-Type, and KLM-Type Fin Tubes. These are ideal for low to moderate temperature applications where cost efficiency, basic corrosion resistance, and effective heat transfer are required.

L-Type Fin Tubes: Feature an ‘L’-shaped foot that wraps around the base tube, offering basic mechanical grip and moderate corrosion protection.
LL-Type Fin Tubes: An upgraded version where each successive fin covers the foot of the previous one—ensuring enhanced corrosion resistance.
KLM-Type Fin Tubes (Knurled): The most robust wrap-around type with knurled tube and fin base, allowing better bonding and improved thermal performance.

The wrap-around construction allows use of thinner base tubes, offering cost advantage while maintaining functional integrity.
