Tube sheets also named tube
plate,Cladding tube sheets 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 ex-changers and
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.
The cladding 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
These are usually
made of low carbon steel material, with a varying thickness based on the
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
The most common types of holes experienced in tube sheet dilling are triangular, rotated triangular, square and rotated square. Each hole pattern presents its own dilling challnges. See typical pattern types below.

Cladding 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
