Tasha manufacturing company fabricates Shell & Tube Heat Exchangers, 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 pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows 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.

There are several thermal design features that are to be taken into account when designing the tubes in the shell and tube heat exchangers. These include:

  • Tube diameter
  • Tube thickness: The thickness of the wall of the tubes is usually determined to ensure:

There is enough room for corrosion

That flow-induced vibration has resistance

Axial strength

Availability of spare parts

Hoop strength (to withstand internal tube pressure)

Buckling strength (to withstand overpressure in the shell)

  • Tube length
  • Tube pitch
  • Tube corrugation: this type of tubes, mainly used for the inner tubes, increases the turbulence of the fluids and the effect is very important in the heat transfer giving a better performance.
  • Tube Layout: refers to how tubes are positioned within the shell..
  • Baffle Design: baffles are used in shell and tube heat exchangers to direct fluid across the tube bundle. They run perpendicularly to the shell and hold the bundle, preventing the tubes from sagging over a long length. They can also prevent the tubes from vibrating.

With our best-trained and experienced team of engineers in thermal and mechanical design and fabrication site, we assure you our best quality of products and services to meet your project requirements.
