Fittings made of food grade stainless steel, or the FOOD&DRINKS series is the latest development of Aignep company for the food industry. The 59-series fittings are certified to NSF 169 standards, which allows their use in the dairy industry, coffee machines, medicine, and other food and beverage products. Fittings for food industry are made of brass CW510L - this alloy of brass has a content of lead that does not exceed 0.25%, which with such a content is usually called lead-free, or without alloying. The sealing ring is made of PPSU, or as it is sometimes referred to Polyphenylsulfone. This amine is a high-quality engineering plastic that retains excellent mechanical, electrical, and thermal properties at high temperatures and loads. With the advantages of such plastic, it is possible to highlight:
- Chemical resistance to dissolved acids, various alkalis, oily materials, fats, benzene, and spirits.
- Does not support combustion
- Absence of corrosion of PPSU fittings
- A system with such materials can withstand decades of cyclic repetitions
- The plastic does not become brittle at low temperatures
- Resistance to gamma and rentgen radiation, possible multi-raised contamination
- Resistance to thermal loads between -50 to +180 degrees.
