Warning – Risk to persons!
Bacteria and chemical substances can contaminate or pollute pipeline systems and the
materials they are made of.
The appropriate installation conditions must be observed in order to achieve an installation
that complies with EHEDG requirements.
For an installation to comply with EHEDG requirements, the process connection/gasket
combinations created by the operator must always be made of parts that conform to EHEDG
stipulations (EHEDG Position Paper: "Hygienic Process connections to use with hygienic
components and equipment").
All weld stub combinations provided by ABB are approved.
The threaded pipe connection conforming to DIN11851 is approved when used in conjunction
with an EHEDG-approved process gasket (e.g. Siersema brand).
