Fin Type Comparison
L Type Finned Tube
Features spiral winding process with L-shaped aluminum or copper fins. Maximum working temperature: 150°C (302°F). Provides uniform lamella distance and high finization ratio.
LL Type Finned Tube
Enhanced L-type design where fin root completely covers base tube surface for improved corrosion resistance. Maximum working temperature: 180°C (356°F).
KL Type Finned Tube
Advanced knurled design with pre-knurled base tube surface and fin roots for superior heat transfer and mechanical strength. Maximum working temperature: 260°C (500°F).

Frequently Asked Questions
What is a fin tube?
A fin tube is a heating element made of copper or steel with square or spiral aluminum fins that distribute heat efficiently. These components replaced traditional radiators and remain essential in industrial heat transfer systems.
Why use finned tubes?
Finned tubes dramatically increase heat transfer efficiency by expanding the external surface area. This allows one finned tube to replace six or more bare tubes, reducing equipment size and project costs by up to 75%.
What is Tension Wound Fin Tubes?
Tension wound fin tubes feature fins wrapped tightly around the base tube and secured at the ends. Our factory produces four types: L, LL, KL, and Crimped finned tubes, each optimized for specific thermal and mechanical requirements.
