Shell and tube configurations

TypeHow it handles thermal expansionCleaning
Fixed tubesheetLimited; an expansion joint may be added to the shellTube side only
U-tubeEach tube is free to expandBundle removable; U-bends harder to clean inside
Floating headOne tubesheet moves freelyBundle removable; both sides can be cleaned

What decides the life of an exchanger

  • Tube material: it must resist both fluids, on the inside and the outside of the tube.
  • Fouling: deposits cut heat transfer, so the design includes a fouling allowance and access for cleaning.
  • Tube-to-tubesheet joints: expanded or welded joints have to stay leak-tight through temperature cycles.
  • Vibration: baffle spacing is set to support the tubes against flow-induced vibration.

Corrosion-resistant construction

Where the process fluid is corrosive, tubesheets, channels and nozzles can be protected with weld overlay cladding instead of being made from solid alloy, which keeps the cost of large exchangers down. We build pressure vessels to the same codes.

What to include in an enquiry

  • Heat duty, or the inlet and outlet temperatures of both fluids
  • Fluids and flow rates on the shell and tube sides
  • Design pressure and temperature
  • Allowable pressure drop and fouling factors
  • Materials, design code and inspection required

Frequently Asked Questions Regarding Heat Exchangers

How Do Heat Exchangers Work?

A heat exchanger passes heat from a hot fluid to a cooler one through a metal wall, usually the tube wall, without letting the two fluids mix. In a shell and tube exchanger one fluid flows inside the tubes and the other flows around them inside the shell.

How are heat exchangers made?

In order to choose a heat exchanger, we must be aware of:
1. Type, temperature, and flow rate of the primary circuit fluid (often the hot fluid). Heat exchangers are designed using a variety of widely used codes from various organizations, including Sec VIII Div 1, ASME, TEMA, HTRI, and others.
2. What you wish to remove from the main circuit (a target outlet temperature or heat dissipation).
3. Fluid type, temperature, and flow rate (often the coolant) for the secondary circuit.

The fields shown above are really the minimum; while completing an enquiry, you should additionally inform us of any restrictions on pressure loss and any additional unique needs.
