Hygienic couplings are designed for the food, cosmetics, pharmaceutical and chemical industries as well as for biotechnology. The couplings must meet the precise demands of hygiene set for the particular application, related to the particular material, cleaning and sterilisation methods which do not require the installation to be dismantled (CIP – Cleaning in Process, SIP- Sterilization in Process).
The hygienic installations and couplings are usually made of AISI304 or AISI316 stainless steel. The coupling must be designed so as not to have any crevices, dead spaces, corners and rough surfaces – not cleanable, where product particles may accumulate causing growth of microorganisms.
