Tube sheets also named tube plate,it is one of the main components in a
shell & tube heat exchanger.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
These are usually
made of copper brass or copper alloy plate, 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
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.
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.
