ASME Bioprocess
Technology Seminars, First time in Europe!
held
in Basel,
Switzerland
Held for the
first time in Europe, the Bioprocess training seminar on Metallic Materials
of Construction on Hygienic Services, exceeded its expectations in attendance,
with 45% international participation.
International
participation included representation from Switzerland, Germany, France,
Italy, Estonia, Japan and India.
Participating companies included Millipore, CIBA, Dockweiler, Inox, Pharmadule,
Hitachi, and more.
The course
materials are available on CDROM for purchase.

Metallic
Materials of Construction for Hygienic Services: Fabrication, Finishing
and Corrosion
|
|
Critical
details of materials selection and fabrication techniques for hygienic
systems were discussed, with focus on the drainability and cleanability
requirements imposed by the ASME Bioprocessing Equipment (BPE) Standard.
Topics such as the practice of and oxide films produced by electropolishing,
a comparison of the surface oxides produced by various passivation
techniques, the technologies used to evaluate oxide films, and the
response of discolored welds to standardized corrosion tests were
discussed.
Topics discussed included:
- Discoloration from welding degrades the corrosion resistance of
the HAZ of 316L stainless steel
- How to prevent internal heat-affected zone (HAZ) discoloration
during welding of stainless steel tubing
-
Under what conditions European materials can be used to build tubing/piping
systems to the requirements of the ASME BPE Standard
- How electropolishing changes the surface chemistry and topography
of metallic materials
- Technologies which are available to passivate the surface of stainless
steels
- The general content of the ASME BPE Standard, including the new
part, currently under development, which addresses materials requirements,
