Jim Wynne,
I thank you very much for your prompt replay, I have already checked what is written in that thread, but I think there is a particularity that I used to write a Failure Report to describe the failure of Mechanical seal, bearing, or sometimes Drive and Driven shafts, but especially Mechanical seal failures occurred several time, the problem was due to the Rotary and stationary ring, but as we have not a chose to change the supplier for the moment, we kept writing FR,
I wanted a quick format to do the job.
