A tube sheet is usually made with a round flat piece of plate, sheet with holes drilled to accept the tubes or pipes in.

An accurate location and pattern relative to one another.

The tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements.

Tubes are attached to the tube sheet by hydraulic pressure or by roller expansion.

A tubesheet may be covered in a cladding material which serves as a corrosion barrier and insulator.

Low carbon steel tube sheets can include a layer of a higher alloy metal bonded to the surface to provide more effective corrosion resistance without using the solid alloy, which means it can save a lot of cost.

Perhaps the best known use of tube sheets are as supporting elements in heat exchangers and boilers.

These devices consist of a dense arrangement of thin walled tubes situated inside an enclosed, tubular shell.

Tubes are supported on either end of sheets which are drilled in a predetermined pattern to allow the tube ends to pass through the sheet.

The ends of the tubes which penetrate the tube sheet are expanded to lock them in place and form a seal.
