The accuracy of tube sheet fabrication, especially the tube hole spacing and tube diameter tolerance, verticality, and smoothness greatly affect the assembly and use performance of the chemical equipment listed above. With the enlargement of chemical equipment and power stations, the tube sheet diameter has become larger and larger, and tube sheets with a diameter of 4m-5m are very common. The characteristics of large-scale tube sheet are large number of tube holes, dense, small diameter, deep, high precision and finish requirements.
The usage of tube sheet:
Tube sheets are widely used in tube and tube heat exchangers, boilers, pressure vessels, steam turbines, large central air conditioners and other industries.
Mainly used in chemical containers, such as tube and tube heat exchangers, pressure vessels, boilers, condensers, central air conditioners, evaporators, seawater desalination, to support fixed tubes. The metal material makes it not only strong It is rigid and has great thermal conductivity.
