Product Description
G Type Embedded Finned Tube
G Type Embedded Finned Tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr, 0.4mm groove depth, then the bottom of the fin is guided into the groove and backfilled with base tube Firmly, finally lock the fins in place by rolling the grooves enclosed in the bottom of the fins. The maximum operating temperature of G Type Embedded Finned Tube can reach 400°C.
