In the production of foodstuffs, it is important during production processes to reduce the risk of contamination andstagnation in the pipe systems to an absolute minimum. Contamination and stagnation can lead to decay of the product."Dead legs" and places where the medium can stand still must therefore be avoided wherever possible. This makesconventional flanges and screwed connections unsuitable, due to their construction. Instead, specifically-designed pipecomponents and fittings are used, primarily manufactured in stainless steel. These have inside and outside surfacesmanufactured to sufficient smoothness, and are easy to dismantle and clean.

The most commonly used tube connection is the four-part screwed coupling compliant with DIN 11851, also known as the"milk coupling". This can be produced as welded coupling for various tube standards, expanding union, and fitted with hosebarb.

The DIN 11864 couplings, produced as threaded coupling and as "clean" flange connection, serve to provide increasedsafety. These couplings are also suitable for aseptic applications.

In principle, fittings and pipe components are suitable for alimentary purposes provided they are manufactured in stainlesssteel, with a minimum of "dead legs", produced to sufficient smoothness and easy to clean.

These connections are also suited to other purposes (e.g. chemical and pharmaceutical industries).

MaterialsStainless steel 1.4301 and 1.4404.
