Abstract: Producing welded connections between inner tubes and tube support plates of a tube bundle for a product-to-product shell-and-tube heat exchanger by means of an auxiliary device is described. A production method includes pressing the end face of a tube support plate against the end face of the inner tubes in the direction of the inner tube longitudinal axes during welding operations with a first form fit, which is effective both radially and axially, immovably fixing the number of inner tubes corresponding to the tube layout pattern to each other by a second, detachable form fit of the auxiliary device, making a circumferential round weld orbitally, starting from the plate inner bore and the tube inner bore, in a single pass and continuously from radially inside to radially outside, and detaching and removing the auxiliary device from the welded tube bundle.

Abstract: An apparatus for influencing the outflow region of a tube carrier plate of a tube bundle heat exchanger, in particular for the food and beverage industry, and more particularly for temperature-sensitive and/or viscous food products in the dairy industry, for example desserts, sauces or concentrates, is described. The apparatus operates so that the tendency for deposits to form in the region of the tube carrier plate through which product flows out is reduced. An annular space-like outlet channel has, at least overall in the region thereof between a maximum outside diameter of an outlet-side displacement body and a second connection opening, a channel passage cross-section, which has a constant cross-section over the entire length of the region and which corresponds to a total cross-section of all of the inner tubes through which a product flows in parallel, which inner tubes each have an individual cross-section.
