Stainless Steel Sanitary Fittings

Stainless Steel Sanitary Fittings

What are the different types of Stainless Steel Sanitary Fittings/Dairy Fittings and their applications?

The food and dairy industries require materials that won’t contaminate the product or harm human health. Stainless steel sanitary fittings generally use grades 304 or 316 and have a polished surface, rounded corners, and easy-to-sanitise designs.

Buyers can order these fittings in various types, like bevel seats, tees, unions, reducers, and elbows:

  • An SS TC clamp, or tri-clover fitting, builds leak-proof piping connections. Clamps can get quickly disconnected for cleaning.
  • Bevel seats and gaskets avoid metal-to-metal contact and support quick disassembly.
  • Tees and elbows manage fluid flow in food and milk pipelines.
  • Unions can manage heavier loads while supporting cleaning.

The internationally accepted standard – in this case, ASTM A270 SS dairy pipe fittings – dictates ½ to 12-inch sizes.

How do you choose appropriate Stainless Steel Sanitary Fittings/Dairy Fittings for a specific food application?

Considering the priorities of the application – dairy, brewery, winery, etc. – helps customers choose appropriate SS sanitary fittings.

  • The excellent corrosion resistance of stainless steel 316 dairy fittings can protect food from rust and battle several acids and salts.
  • Consider the temperature and pressure (up to 1,450 psig and 450° F).
  • Decide the polishing type, like mechanical, electro-polish, etc., and the number of grits.

Note that sanitary and SS dairy fittings are similar, but for their certificates and additional design/testing nuances.

Which comprehensive tests are performed on dairy sanitary and dairy pipe fittings ?

Standard quality checks on SS 304 sanitary fittings use a spectrometer or an analyser gun to verify the chemical composition. They must get produced with tight tolerances (usually set to +/- .005″ and a maximum 12.5% variation for the wall thickness).

Stainless steel tri clamp fittings also undergo visual inspection to detect surface imperfections. They also get evaluated for intergranular corrosion (especially for pharmaceuticals), flattening, tensile strength, and non-destructive hydrostatic examination.

The Mill Test Report for stainless sanitary fittings contains traceable heat lot numbers for the buyers’ reference.
