Improving valve quality
Ive read an article that might be of interest.
Long time ago, T. M. Rogers from Alberta Canada was having a
problem. About 3 dozens API 600 valves failed while in-service in
short-period of time. Failures were not in any way associated with
corrosion or erosion problem and the plant environment is classified
as moderate.
The early failure of the valves affected the plant production
output, naturally the operation superintendent put a pressure to
maintenance/technical to improve the reliability of the valves. They
figure that's the effective way to do it is by ensuring the quality
of the valves purchased. Question is how does one develop a program
that will improve valve quality without necessesarily jacking the
cost of the commodity beyond an acceptable limit (u pay the price
for quality).
Well, TM Rogers took the challenge and cameout with a 6-step program that proves a success. After the program was initiated only one inservice failure of valve purchase under the program failed (they were able to prove that the valve supplied was defective and got reinburse ). TM Roger works for Syncrude Canada when the article cameout.
If there is any interest I can summarize the highlight of TM Rogers 6step valve quality improvement program and post it. Received on Fri Jul 26 03:13:00 2002
