Product Description
DELLOK KL Type Spiral Finned Tube
DELLOK KL type spiral finned tubes, also known as knurled finned tubes, combine wrap-on and embedded technologies for superior thermal performance. The fins are manufactured from preformed L-shaped strip material, continuously helically wound under tension onto pre-knurled base tubes.
Technical Specifications

Key Features
- Enhanced thermal performance with minimal thermal resistance
- Knurled base tube and fin foot combination for tight bonding
- Continuous helical winding process for uniform fin spacing
- Base tube protection from air erosion
- High finization ratio for optimal heat transfer
- Fins secured at each end to prevent unwinding
Manufacturing Process
The KL finned tube manufacturing involves pre-knurling the base tube surface, then winding preformed L-shaped fin strip under tension. The fin foot is rolled into the knurled tube surface, creating a secure mechanical bond that enhances heat transfer efficiency.
Industrial Applications
- Petrochemical industry air coolers
- Power generation systems (fossil and nuclear plants)
- Paper making and tobacco industry equipment
- Building heating systems
- Food industry spray drying systems
- Waste incineration equipment
- Compressor coolers and air conditioners
