Description

Technical Field

[0001] The utility model relates to the technical field of flange tube sheets, in particular to a flange tube sheet used in a tubular heat exchanger. Background Art

[0002] The flange tube sheet is an accessory with a hole slightly larger than the outer diameter of the tube drilled on a circular steel plate. It is mainly used to fix the tube and seal the medium in the heat exchanger. It is fixed by passing the tube through and welding it. Its processing accuracy, especially the tube hole spacing and tube diameter tolerance, verticality, and smoothness, greatly affect the assembly and performance of chemical equipment. The flange tube sheet is mainly used in industries such as tubular heat exchangers, boilers, pressure vessels and steam turbines. The metal tube sheet flange is required to have not only high rigidity but also good thermal conductivity. The existing flange tube sheet of tubular heat exchangers has certain disadvantages when used. The diameter of the holes on the tube sheet is fixed and cannot be adjusted according to pipes of different specifications. The adaptability is poor. The tube sheet is fixed by welding, and after welding, its surface is uneven. When the liquid flows through it, impurities are easily embedded in it, which is difficult to clean. For this reason, we propose a flange tube sheet for tubular heat exchangers. Utility Model Content
