5-271-12-120-002

Built around a two-pass U-bend bundle, this configuration delivers in-tank heating with steam in the tubes for demanding service. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Physically, the unit runs a 12-inch shell, 120-inch shell length, and roughly 120-1/4 inches overall in a 2-pass arrangement. That works out to about 212 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-271-12-120-002. Installations range across hot water storage tanks, wash-down and sanitation water storage, and process tank heating.
