Hygienic Unions / Couplings come in different standards
The different unions above represent different Sanitary Standards . SMS (Swedish Milk Standards), DIN (German Standards), RJT (Ring Joint Type), IDF (International Dairy Federation, 3A (American FDA Standards).
The most important differences between these standards are
-
Welding Outer Diameter, Inner Diameter, and Thickness, you need to use Unions from the same standards as your pipe line to make sure you can weld them together
-
Design and thread size- Different designs means Unions from different standards are incompatible with each other, you cant lock an SMS Union with a Nut from a DIN Union.
-
Tri Clamp Unions can be tightened and loosen without any special tools, while the rest require compatible spanners.
