- the tubesheet comprises a stack of a plurality of tubesheet plates having at least one passage opening for receiving a respective tube of the tube
- Tube bundle heat exchanger Tube bundle heat exchanger.
- the passage opening is by means of at least one
- Heat exchangers for high corrosive use are typically provided with tubes of a corrosion resistant material such as e.g. Graphite, silicon carbide, glass or PTFE built.
- the tubes contain a first fluid and are surrounded by a second fluid located in an inner housing region, so that a heat exchange between the first and the second fluid can take place through the tube walls.
- the inlets and outlets of the tubes are separated by a tubesheet from the inner housing portion, so that the incoming and exiting first fluid can not mix with the second fluid. For this purpose, an excellent sealing of the tube bottom is crucial.
- the tubesheet of a typical such heat exchanger is typically constructed of one or more tubesheet plates with a plastic-coated metal core.
- Plastic sheath may comprise, for example, a chemically resistant material such as PFA or PTFE to allow use with corrosive media (first and / or second fluid).

- the stack has at least one passage opening for receiving a respective tube of the tube bundle heat exchanger.
- the tubesheet has, for each of the at least one through-opening further: at least one sealing ring for sealing the respective tube, and at least one sealing seat for receiving the at least one
