Stainless Steel DIN 11851 Unions

The complete stainless joint DIN 11851 is composed of the union of a male conical pipe coupling, together with a female threaded pipe coupling, both of them connected by a swivel. This is done in order to guarantee an easy cleanliness of pipes and plants, where the joint is used.

What are DIN 11851 standards?

The acronym DIN indicates the Deutsche Institut für Normung (the German institute for the standardization).

The German standard DIN 11851 is absolutely the most used in the food-, beverage-, enological, dairy- and confectionery sector.

Why do we use the stainless steel Fitting DIN 11851?

The stainless steel fitting DIN 11851 is widely used in Italy, all over Europe and it is also expanding its use in other countries worldwide, thanks to its feature, having the swivel on the male part. This is different from the screw-shaped systems, where the swivel is combined with the female part.

How is divided the stainless steel Fitting DIN 11851?

The stainless steel fitting DIN is divided into weld fitting and expanding fitting.

Weld stainless steel fitting

The weld-stainless fitting DIN allows the butt welding of the extremities of the male pipe coupling and the female pipe coupling with the related pipes.

Expanding stainless steel fitting

The expanding stainless fitting allows the union of two couplings through the expanding technique.

The expanding technique is a mechanical operation which allows the assembly of two elements through an expansion (also called deformation), which does not compromise the mechanical completeness and guarantees a watertight gasket (also thanks to the inner welding).
