ASME SA240 SS304 Stainless Steel Tubesheet For Heat Exchanger
The heat exchanger tube sheet is a circular plate that fixes the tubes and seals the medium in the heat exchanger. The heat exchanger tube sheet is a pipe fitting that can be welded to fix the pipes. The composite tube sheet we provide can save resources and reduce costs without reducing the use effect (corrosion resistance, mechanical strength, etc.).
Depending on the application, a tube sheet may be made of various metals or of resin composites or plastic.
A tubesheet may be covered in a cladding material which serves as a corrosion barrier and insulator and may also be fitted with a galvanic anode.
Tubesheets may be used in pairs in heat exchange applications or singularly when supporting elements in a filter.
Key features of stainless steel tubesheets:
1. Material: Stainless steel is selected for its excellent corrosion resistance and mechanical properties. The specific grade of stainless steel used depends on the application and the environmental conditions to which the heat exchanger will be exposed.
2. Corrosion resistance: The corrosion resistance of stainless steel is critical in heat exchanger applications, as heat exchangers may be subject to a variety of chemicals and temperature fluctuations.
3. Thermal conductivity: Stainless steel has good thermal conductivity, which allows for efficient heat transfer between the tubes and the tube sheet.
4. Mechanical strength: The tube sheet must withstand the mechanical stresses caused by the pressure difference between the fluids on both sides of the heat exchanger.
5. Tube arrangement: The tube sheet is designed with holes or tube holes to accommodate the tubes, and the arrangement of these holes may vary depending on the type of heat exchanger and requirements (for example, fixed, floating, or U-tube heat exchangers).
6. Welding: In most cases, the tubes are welded to the tube sheet to ensure a secure and sealed connection. The welding process used should match the material properties of the stainless steel and be suitable for the intended use.
