Had an example of this at my plant a while back.
Used Tantalum-lined piping (big $$) in one unit, some was installed in a methanol service after a recovery column.. turns out super "dry" MeOH pits tantalum and you need some small fraction of water content to avoid it. Now SOP is to run the...
Bernoulli31, this is amazing.
My company completely removes any .pst or archiving, yet anything over 2yrs old is gone forever. Oh and my entire mailbox limit is 1GB. Needless to say, I'm in dire need of a better way to organize and archive my files. This pdf looks promising as it maintains the...
If you are in the US is it actually illegal for your employer to not allow open salary discussions. It remains a policy at many companies though because the less you chat w/each other about wages the less they can pay everyone.
Not to toot my own horn, but I think it worked very well for me. I struggled with initiating first contact or developing my own priorities, etc and the trial by fire forced me to do just that. If someone was constantly telling me exactly what to do or I had a "Safety net" to fall in, I know I...
No formal mentoring or training for me when I hired in out of school. Very much got the "trial by fire" approach.
Half the battle was figuring out who was the right person to even ask the question to. Most people/ other engineers we always very helpful, but I had to initiate everything and learn...
Yes, these added couplings are becoming more and more standard for lined pipe manufacturers. CRP has them standard, as does Baum (I believe). Resistoflex's ATL line does as well. The nipple extensions serve to vent the permeants further away so the vapors don't interact with moisture in the air...
As others mention, the lining is effectively ignored when doing pressure calculations. The steel is doing the overwhelming majority of the work.
Regarding the vent holes, I am assuming you mean the small holes in the steel pipe wall for permeation evacuation. These are generally ~1/8" and are...
I think he is asking if vessels are manufactured in common sizes similar to piping. i.e. piping has 1", 2", 4", etc nominal sizing. As such, I think the question is are vessels fabricated in "common" or "standard" sizes i.e. 24", 36", 72", etc.
In my experience, no, most pressure vessels are...
AS StoneCold alluded to, the Ta patch is more than likely just that, a patch. It is one of the most common, reliable repair techniques for a defect in the glass (if not at "sharp" radius/curvature area). Perhaps there was a defect in the initial manufacturing, and rather than scrap the entire...
I've had similar issue due to CUI (6" pipe, xray shows as thin as ~0.075" remaining).
Basically what I've heard is no option for composite wrap or anything of the sort without disturbing the scale, which isn't an option while running for safety reasons. If scale isn't so bad and you can wire...

In my experience during college and working professionally since then (graduated 5 yrs ago) generally the 4-8 mo internships are done while still as an undergrad student, before graduation. So there really isn't much of a conflict with full-time offers for most students taking...
