Within the process industry, we mainly work with 3 different forms of aseptic fittings:
The aseptic DIN standard is available for 3 different kinds of pipe connections, namely series A/B/C:
Our aseptic fittings come in stainless steel AISI 316L as well as with various surface roughnesses, typically between Ra <0.8 µm and Ra <0.4 µm depending on requirements and specifications. All 3 connection standards also apply in e.g. biotechnology and cosmetics production.
The DIN standards saw the light of day in Germany as to meet the high hygiene requirements of the country's food, chemical and pharmaceutical companies. As with both weld on, flange and Clamp, aseptic DIN fittings are used for process plants, which require not only a very high level of purity of the liquid media in flow, but also the general hygiene.
