A shell and tube heat exchanger 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.

    Fluid Flow in Heat Exchanger

    Tube Side Flow :
    Different Pass Arrangements are made, Like Two and four pass designs are common because the fluid can enter and exit on the same side. This makes construction much simpler and Helps to Limit the tube Length.

    Shell side Flow :
    There are often Baffles directing flow through the shell side so the fluid does not take a short cut through the shell side leaving ineffective low flow volumes. The Counter current heat exchangers are most efficient because they allow the highest log mean temperature difference between the hot and cold streams.

    Final Design Validation :
    Since the heat demands of the process are not constant, and the heat content of the two fluids is not constant either. Our heat exchangers will be designed for the worst case and will be controlled to make it operate at the particular rate required by the process at every moment in time.

    Our heat exchangers itself is not constant. Its characteristic changes with time. The most common change is a reduction in the heat transfer rate due to fouling of the surfaces. Exchangers are initially oversized to allow for the fouling which gradually builds up during use until the exchanger is no longer capable of performing its duty. Once it has been cleaned can use further.

    Types of Shell and Tube heat exchangers

  • Fixed-Tube Sheet Design.
  • Full-Through Floating-Head Design.
  • Tubes can be 'U' bundle.
  • Split-Ring Floating-Head Design.
  • Bayonet Tube Design.

    Applications of Shell and Tube Heat Exchangers:

  • 1. Power Plants – Condensers, Pre Heaters, Waste water treatment
  • 2. Oil Refineries – Inter cooling Purpose, Re Processing Purpose,
  • 3. Manufacturing Industries – Oil coolers for Quenching Oil
    Oil coolers for Lubrication Oil
  • 4. Offshore Industry Water Makers
    Condensers
  • 5. Nuclear Power Plants – Chillers and Water Coolers
  • 6. Food and Dairy Industries
  • 7. Refrigeration systems
  • 8. Pulp and Paper Industries
  • 9. Wine-brewery industry
  • 10. plastic and Fertilizers Industries

    A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and the second runs over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes: plain, longitudinally finned, etc.
