shell and tube heat exchanger. It is the most common type of heat exchanger in all Industries. Mostly used in higher-pressure and Higher Temperature applications.

This types of Heat exchangers are having two divisions one is shell and other is Tubes. Here One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. For this purpose seamless/ERW or Rolled pipes are used for shell. And Seamless tubes are used for Tubes.

Our Shell and Tube Heat Exchangers Design Process Contains Two Parts - Thermal and Mechanical Design

Part A - Thermal Design

·                       1. Consideration of Process Fluids in both Shell and Tube Side,

·                       2. Selection Of Required Temperature Specifications,

·                       3. Limiting the Shell and Tube side Pressure Drop,

·                       4. Setting Shell and Tube Side Velocity Limits,

·                       5. Finding Heat Transfer Area Including Fouling Factor.

·                       Part B- Mechanical Design

·                       1. Selection of TEMA Layout – Based on Thermal Design

·                       2. Selection of Tube Parameters – Size, Thickness, Layout, Pitch, material

·                       3. Limiting the Upper and Lower Design on Tube Length

·                       4. Selection of Shell side Parameters – Material Baffle Cut, Baffle Spacing, and Clearances

·                       5. Thermal conductivity of tube material.

·                       6. Setting upper and Lower Design Limits on Shell Diameter, Baffle Cut, Baffle Spacing. 
Shell and tube heat exchanger is One type of Closed Circuit cooling Equipment.
