Description

DUPLEX STEEL TUBESHEET ASME SA240 S31803 S32205 FOR HEAT EXCHANGER

What is tubesheet for a Heat Exchanger?

Tubesheets have holes drilled to accept a series of tubes inside of an enclosed tubular pressure vessel. These pressure vessels, commonly referred to as shell and tube heat exchangers, are the most common heat exchangers used in oil refineries and large chemical plants. The tube sheet itself serves as a supporting element in heat exchangers and boilers. The tube sheet is called this because the tubes–which are carefully arranged in a specific pattern–penetrate the tube sheet in multiple places to allow the fluid within these tubes to flow in and out of the heat exchanger. The fluid flowing through the tubes within the shell exchanges heat with the fluid that flows into the shell but flows past the outside of the tubes exchanging the heat with the tube fluid.

A tubesheet is usually made from a round flat piece of plate,sheet with holes drilled to accept the tubes or pipes in a 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 the expense of using the solid alloy,which means it can save a lot of cost.
