Shell and Tube Heat Exchanger Design

Design consideration:

• The Valve and Blind Flange should be placed in the nozzle as directly as feasible.
• When installing the Piping and Valve Handwheel near the Heat Exchanger, minimize the proximity to the Exchanger Flange as much as possible. Keep it away to give more access to the exchanger flanges.
• The Heat Exchanger connecting pipe design should aim for simplicity, avoiding any unnecessary loops or pockets.
• If the Heat Exchanger operates in parallel and lacks a valve in the connection line, it should be set up with a symmetrical piping arrangement.

• In the event of Heat Exchanger installation as a group, ensure that the Coolant Piping and operating Valve are arranged in the same direction and at the same height to reduce the potential for operational errors by workers.
• If the Heat Exchanger is mounted within a structure, verify clearance with the hoist beam and take special precautions to prevent pipe installation in the hoist operation path.
• When disassembling the Heat Exchanger Tube, it is advisable to install a removable spool to facilitate the dismantling process within the Pipe. Additionally, position the support correctly to prevent the pipe from hanging down during Short Piece Removal.

• To facilitate field HydroTest and Flushing of the Heat Exchanger Bottom Connection Pipe, an Adjustable Support should be placed where the Blind Flange is to be inserted into the Nozzle.
• Design Heat Exchanger Piping overhead to ensure adequate space and arrange it in groups for ease of support. Keep in mind, the heat exchanger fix position.
• Heat Exchanger Connected Piping must have sufficient flexibility to absorb the thermal expansion of equipment.
• Provide appropriate support to prevent the nozzle from being affected by the weight of the Pipe or excessive load resulting from thermal expansion.
• The handling of valves can pose challenges, particularly when dealing with stacked valves, as indicated in the caption below. To address thermal expansion concerns on both piping and equipment, consider securing the lines on the stationary side of the saddle.
• Keep as much accessibility of the manual valves and instruments as much as possible.
