5-272-12-036-001

A double-wall two-pass U-bend bundle gives this configuration the thermal and mechanical margin expected of Diamondback tank heater equipment in in-tank heating with steam in the tubes and cross-contamination protection. The vented air gap between tube walls gives a visible telltale leak rather than allowing tank contents and steam to mix. The configuration measures 12 inches across the shell, 36-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-272-12-036-001. As furnished, materials include cast iron bonnets, steel shell, and copper (double wall) tubes. Design ratings run to 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature.
