I am presently working on a facility where they have a large number of valves from an italian manufacturer (who shall remain nameless). Apart from problems with real variable stiffness from one valve to another we have a major issue with the double seated expanding gate valves. These are used in...
Apologies if this is an obvious question, but I have a problem on an FPSO where part of the sea water pipework is made from galvanised carbon steel and the exchangers fed by the sewater are plugging up regularly with a fine material that seems metallic. The other sea water systems are made from...

We have been experiencing some failures in a sea water system of some triple offset hard metal seated laminated butterfly valves, the laminate is described as ASTM A479 type 316 Ti/Graphite and you can see various layers.
We know we have had some failures of rubberlined butterfly valves...
My company has had a lot of poor experience of running dry low emmisioins turbines supplied by Siemens on dual fuel (especially related to diesel quality off of west africa). We are presently considering going to some Solar low NOx turbines in the same area and still dual fuel. I know that our...
We are experiencing a large number of failures of the seats on some rubber lined (carbon steel bodied) butterfly valves we have installed in a sulphate reducing package (sea water filtered to 5 microns with occasional acid and alkali washes).These valves have to seal against 20 bar(g) and are...
