Abstract: A tube plate for tube bundles for chemical reactors and heat exchangers in general, includes a plurality of components, with shapes that are complementary to one another, in order to form a complete plate. The components may be produced separately, and are connected to one another subsequently by means of mechanical joints, in order to form the tube plate. The components which form the tube plate are joined to one another by of a plurality of pins, or other mechanical connections, which are inserted in corresponding holes provided in the respective components. This joint can be completed by means of welded connections on the mechanical connection parts.

Abstract: A device used as a chemical reactor or heat exchanger in general, with a thin tube plate, of the type in which at least one pipe is connected to a tube plate, this tube plate being closed by a chamber with a container function, wherein this chamber is produced by a section with any shape, with a base which is joined to the plate by a lateral portion; connection elements are also provided between the tube plate and the base of the chamber.
