Heat Exchangers Machining Solutions

The tube sheet is one of the main components in a shell & tube heat exchanger.

Depending on the tube bundle configuration, a heat exchanger can be equipped with one or two tube sheets.

These are usually made of low carbon steel material, with a varying thickness based on the fluid pressure.

Depending on the final application (petrochemical, nuclear, oil&gas, etc.) the tube sheet can be cladded with Stainless Steel or other Super Alloys or even be entirely made out Stainless Steel or Superalloys.
