What is a Tube Sheet?

A tube sheet is a precision-engineered metal plate used to support and secure tubes within pressure vessels such as shell and tube heat exchangers, boilers, and condensers. It forms the backbone of tube alignment, facilitates fluid flow segregation, and withstands thermal and mechanical stresses during operation.
