Rolling of finned pipes of high corrosion-resistant metals and alloys.

摘要

New solutions and tendencies in construction of heat exchangers are presented. The criterions for optimization of the rolling technology for low and high finned pipes, of high corrosion-resistant metals and alloys, are defined. Geometrical parameters of pipes and ribbing acquired during rolling-investi-gations, verified in conditions of industrial production, are compiled in tables. New solutions for finned pipes with copper radiator, and a bimetal pipe of the kind Al-Ak11 of high strength and corrosion-resistance in comparison to monometallic aluminium pipes, have been worked out.
