Connection standards and applications

Within the process industry, we mainly work with 3 different forms of aseptic fittings:

  • Aseptic unions connection – form 1 (DIN 11864-1)
  • Aseptic flange connection – form 2 (DIN 11864-2)
  • Aseptic Clamp connection– form 3 (DIN 11864-3)

The aseptic DIN standard is available for 3 different kinds of pipe connections, namely series A/B/C:

  • Series A has a pipe connection to DIN food pipes
  • Series B has a pipe connection to ISO pipes
  • Series C has a pipe connection to DS/SMS food pipes

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

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.
