How to Choose Sanitary Couplings for your Applications?
A coupling is a device used for connecting two shafts with an aim to transmit power. Coupling usually doesn’t allow disconnection of shafts during operations with the exceptions of few kinds of couplings that can slip or disconnect when the torque limit is exceeded. In a more general sense, a coupling may also be a mechanical device for connecting the ends of adjacent objects. There are many different kinds of couplings used for different purposes. Sanitary couplings are generally used in food, beverage, medical, pharmaceutical, portable water, marine applications, and biological applications where cleanliness and sterility are required. These couplings are constructed of materials that ensure a sterile environment and maintain sterility during usage.
The most common sanitary hose assembly used by most of the above-mentioned industries is one finished with tri-clamp ends. These types of sanitary hose or sanitary couplings are used across many industries. Each industry has its own terms, but sanitary is the most prominent requirement in these industries.
The common requirement for hose and fittings in any of these industries is that the product must be made of a material that is easy to clean from a biological context and will not encourage the growth of bacteria. Each of these industries has its own specific codes and standards to define the performance and material characteristics of the products. For instance, when one is looking for sanitary fittings for food-grade applications, it should have a finish that is safe for processing food products and can easily and reliably be cleaned and sanitized. Also, the grinding, sanding, and finishing of food-grade stainless steel should de devoid of areas that may stimulate bacteria growth. Selecting the wrong product can have serious repercussions leading to line shutdown, contamination, and wastage of the process material. Besides, the surfaces of the fittings must be able to withstand corrosion from the food being handled and the chemicals used to sanitize the equipment.
Stainless steel tri-clamp couplings and sanitary couplings are popularly used within the food, beverage, and pharmaceutical industries. It is easy to create a leak-proof connection allowing easy assembly or disassembly for routine maintenance and inspection with stainless steel couplings.
In the current context, when cleanliness is the prominent demand across every industry, it is equally important to recognize and understand the standards of sanitation. While looking for sanitary couplings, it is prudent to look for those made according to tri-clover and industry regulations with tri-clamp joints, hose shanks and welding ends. It is also recommended to buy products that meet American 3D sanitary standards and European EHEDG guidelines. By careful selection, right installation, and regular maintenance of fitting, one can ensure the longevity of the fittings, while saving a substantial amount of money in the long run.
