Introduction:    

Tube sheet is one of the main components in a shell & tube heat exchanger.Tube sheets also named tube plate,have holes drilled to accept a series of tubes inside of an enclosed tubular pressure vessel.The tube sheet itself serves as a supporting element in heat exchangers and boilers. Tube sheets have different sizes and a series of holes are done to create a place where the tube ends are welded.Also called tube plate.There are two types: floating tube sheet and stationary tube sheet.

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.

Typical Hole Patterns

Applications：

Tube plate is widely used in tubular heat exchangers, boilers, pressure vessels, steam turbines, large central air conditioners, condensers, evaporators and other products. The metal material makes it not only rigid, but also has great heat conduction performance. The precision of tube plate processing, especially the tolerance of hole spacing and diameter, perpendicularity, and finish greatly affect the assembly and performance of the equipment listed above.
