ASTM A182 F316L 1.4404 Corrosion Resistance Tubesheet مبادل حراري

A tubesheet is a plate, sheet, or bulkhead which is perforated with a pattern of holes designed to accept pipes or tubes. These sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements.

Depending on the application, a tube sheet may be made of various metals or of resin composites or plastic.

A sheet tube may be covered in a cladding material which serves as a corrosion barrier and insulator and may also be fitted with a galvanic anode.

Tube sheets may be used in pairs in heat exchange applications or singularly when supporting elements in a filter.

What is a heat exchanger?

A heat exchanger can be defined as any device that transfers heat from one fluid to another or from or to a fluid and the environment.They are specifically designed for the efficient transfer of heat from one fluid to another fluid over a solid surface.

Exchanger Type

Select the type of heat exchanger.

• U-Tube has only one tubesheet. The tubes are bent in the form of a "U." The bundle can removed for maintenance, but the inside of the tube is harder to clean because of the bend.

• Fixed has two tubesheets that are fixed at each end of the exchanger and are connected to each other by straight tubes. Both the tubesheets are stationary, so differential thermal expansion can develop between the shell and the tubes. An expansion joint is sometimes required to absorb the thermal growth. You must select a fixed type of tubesheet exchanger to perform finite element analysis (YUHONG) on expansion joints.

• Floating has one tubesheet that is fixed (stationary) and one that is free to move. Because one tubesheet floats, any differential thermal expansion between the shell and tubes is absorbed. This category of exchangers is the most versatile and also the costliest. Tubes can also be cleaned easily compared to U-tube exchangers.

Stainless steel 316L Chemical Composition %

What is the material of tube sheet?

These are usually made of low carbon steel material, 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.
