“G” Embedded Fin Tube, also known as G-fins (grooved fins), is widely used throughout the world. The fin strips are mechanically forged into the machined grooves and are securely locked into place by back filling with the base tube material. This ensures a mechanical bond with the tube and have negligible fin bonding and thermal cycling degradation. Typically, the fins are made of aluminum or copper. “G” Embedded Finned Tube is suitable for high working temperatures up to 400°C.

TIANLI Heat Transfer can offer Embedded Finned Tubing (Embedded G type fin tube) where exceptional thermal efficiency at higher temperature ranges with solid fin-to-tube contact is required. Fins are embedded or locked into the helical groove on the outside of the tube. Rollers press metal that has been removed from the groove against the base of the fin to form a lasting metal-to-metal bond. The type of fin to tube construction works best in temperatures below 400°C.
