Abstract

Rolling of high-fin integral finned tube from stainless steel or other difficult to form material, in two operations with an annealing step between rolling operations. Each rolling operation quickly forms narrow helical grooves to displace metal into wide helical ribs or rib portions, followed by more gradual widening and deepening of the grooves with additional metal displacement, and lateral application of pressure to the ribs to form it to required fin shape.
