The Chairman
(Robin Oakley) opened the meeting.
This was postponed until after lunch.
2.1 Corrosion of Tidal Turbines, Stephen Turnock, University of Southampton
2.2 Detection
of Corrosion & Material Degradation Using Ultrasonic Pulse Echo, TOFD and
Phased Array Applications, Tim Armitt, Lavender NDT
3.1. Phil
Dent (Exova) raised a question about the maximum safe operating temperature for
superduplex stainless steels which will avoid the occurrence of 475°C
embrittlement through the precipitation of the α phase. This was
answered by Roger Francis, from his experience with ZERON 100 (UNS S32760).
He suggested that the highest design temperature for long term operation
should be 280°C. However, running
at a higher temperature did not necessarily cause failures.
He related an example he had heard in an informal discussion, where a
superduplex pipe had been operated for 8 years in the temperature range 320-330°C
with no apparent effect. However,
when the pipe was removed in a maintenance operation, it was accidentally
dropped and it shattered into several pieces!
3.2. Clive Tuck (Lloyds Register) asked if anyone knew of a suitable person who was an expert on the subject of boiler corrosion and suitable water treatment methods which could be used for the prevention of such corrosion. No names were forthcoming at the meeting
3.3. Roger Francis (RA Materials) asked whether there was any experience of 70/30 copper-nickel for instrumentation tubing in a Zeron 100 seawater pipe line. The consensus was that it would be a problem. Some practical examples suggested were Zeron to NAB (BP Andrew) and racing boat fittings.

NEWS
Although most meetings have four presentations, the January meeting has traditionally had three, the remaining time being taken up with the AGM. The Chairman explained that there would be slots for 2 or 3 short (about 10 minute) talks from members at the January 2010 meeting, as recent AGMs were not taking up very much time. Anyone wishing to offer a short presentation in January should contact him, or the Secretariat.
CPD certificates would be available from the Secretariat as usual, following the meeting
4.1 An Interesting Corrosion Problem with Titanium, Peter Morgan, BAE Systems
4.2 Cathodic Protection of the Thames Barrier, Brian Wyatt, Corrosion Control
The Chairman closed
the meeting at approx. 3:30 pm
Note: Several of these presentations are available in pdf format to staff of MCF member companies. Please contact the Secretariat for details.
