Aluminum & Copper Fins Are Embedded Into SMLS Stainless Steel Tube of TP304 / TP304L
Energy Transfer embedded finned tubing offers exceptional thermal efficiency at higher temperature ranges with solid fin-to-tube contact. Fins are mechanically locked into a helical groove in the outside of the tube. Rollers press displaced metal from the groove against the base of the fin to form a lasting metal-to-metal bond.
Quick Detail:
Finning Facilities: 5 finning machines.
Daily capacity up to 3500 meters.
Tube OD: 50.8mm(2'') max.
Tube Length: 18,000mm max.
Fin Height: 16.5 mm max.
Fin Thickness: generally 0.4mm ~0.6mm
Fin Pitch: 2.1 mm (12FPI) min.
