5-151-20-156-001

For general industrial liquid-to-liquid heat transfer, the OC straight tube line offers a removable straight-tube bundle design; 5-151-20-156-001 sits within that range. An internally packed floating rear tubesheet absorbs differential expansion, and the bundle pulls for straight-through mechanical tube cleaning. Its envelope centers on a 20-inch diameter shell, 156-inch shell length, and roughly 176 inches overall in a 1-pass arrangement. That works out to about 1011 square feet of heat transfer surface on 5/8-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 125 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Common applications are process heating and cooling, oil and quench cooling, and chemical and refinery duty.
