Product Description
DELLOK Copper G Type Finned Tube
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) specializes in manufacturing high-performance finned tubes for industrial heat transfer applications.
Product Overview
The G Type finned tube features fins embedded into the outer wall of the tube, designed for continuous process applications in demanding industrial environments including refineries, petrochemical plants, fertilizer facilities, and gas processing plants.
Manufacturing Process
Our advanced manufacturing utilizes specialized tooling with non-cutting plates set at 90° to the tube axis. The process creates precise grooves for metal spinning and securely embeds the fin foot through controlled pressure application. Tungsten carbide tooling enables production with austenitic steel and exotic alloy base tubes.
Key Advantages
- Exceptional fin stability and dimensional integrity
- Superior heat transfer efficiency
- High operating temperature capability up to 450°C
- Resistance to mechanical and thermal shocks
- Reliable mechanical bond between fin and tube
