As a leading Korean manufacturer of premium fin tubes, we strive to deliver top-tier quality, fast and flexible service, competitive pricing, and complete customer satisfaction. Our commitment to excellence and continuous improvement is at the heart of everything we do.

Embedded finned tubing is engineered for superior thermal efficiency, particularly in high-temperature applications. Its design ensures optimal heat transfer performance through a robust metal-to-metal bond between the fin and the tube.
Each fin is mechanically embedded into a precisely machined helical groove on the tube’s outer surface. During the manufacturing process, specialized rollers displace the groove’s metal and press it tightly against the base of the fin. This creates a secure, continuous contact area that maximizes thermal conductivity and ensures long-term durability, even under extreme operating conditions.
This construction method eliminates the risk of fin loosening or separation, making it ideal for demanding heat exchanger systems in power generation, petrochemical, and industrial processing environments.
