Thank you for clearing up the reason for the laminations. The good thing about this job is that I know I won't get bored with the same things day in, day out.

In this case it does like the laminated fins do provide for cooling...
gtaw, interesting and good point. I don't know how the new paint system compares (type, thickness etc) to the old one that didn't work so well. Though the company that did the refurbishment of the motors is one of the better known ones in the motor manufacturing industry. Hopefully they know...
Thank you for your replies.
TugboatEng, I had wondered whether isolating the housing from the stainless frame could be an option.
Thanks also for the clarification on the cathodic protection. I had thought that a generally very damp environment would be sufficient - so good to not go...
I have been asked to look at adding cathodic protection to some cooling tower motors. Approximately one year ago the cooling tower structure was replaced with stainless steel. The motors mount directly to the SS. Since then the corrosion of the motor housing and the bare part of the motor shaft...
This is pretty much the work-around I did as a test, adding these either side of the vertical expansion loop. The result for the piping was quite OK.
Using a wider and more rigid pipe shoe is something we are looking at. Supports on the verticals to restrain lateral movement would certainly be...
Hi, I have been visiting these forums for a while and have learned a lot of good stuff, thank you. Now time for a question:
We have a design for 10” carbon steel pressure piping (ASME B31.1). The pipe has a long straight section near ground level, with a series of vertical expansion loops (4m...
