This is not a technical post, but I think just maybe site management might forgive me for this post. In a private forum that I am not sure is visible to all, Pat Primmer's daughter has posted on Pat's account to let us know that Pat recently passed away. His funeral will be Monday March 4. He...
Would some really good metallurgist go up to thread108-326877
and see if there is a metallurgical reason for what the OP has posted regarding Eaton's claim that grease degrades 5160 spring steel? Even if you aren't a good metallurgist, give it a try anyway.

Does ASME BPV deal with the use of a sacrificial anode plug in the pressure boundary of a stamped vessel?
It seems to me that with Corrosion Allowance, additional thickness is added over and above min required metal thickness with the expectation that over time corrosion could reduced the...
Does this reach out and touch any Forum Members?

Any forum members have any experience with welding Cu-Ni (preferably 90-10) tubes directly to a SS tube-sheet without any overlay material, any grade of SS but especially 304 or 316? And yes, I did a search on this site but came up with nothing (one thread that was about expansion).
Thanks,

I am wondering if anyone has had any particular experience with Aerotight nuts, specifically stainless nuts on stainless bolts in medium temperature service (400F/200C) where the bolts or nuts have to be repeatedly removed and reinstalled. I am looking for any issues with galling due to the...
I did a search and didn't find anything posted in this forum since 2005. Is anyone aware of the latest developments / progress on this technology?

If a Sec VIII Div I vessel is designed, stamped and submitted to a certifying agency with a paticular size and grade of bolt for its flanges that connect to external piping, is the ultimate installer and/or user of the vessel compelled to use the bolt size and grade that is shown on the vessel...
When a schedule number has an "S" behind it, it indicates that it is a Stainless (or is it other alloy as well) pipe. An example would be 4" Schedule 10S indicates a 4 inch schedule 10 stainless pipe.
What and/or where is the standard that states that the "S" designator signifies Stainless (or...
Imagine a piece of pipe of a couple of meters length on a set of rollers free to rotate. This piece of pipe has one 90 degree LR elbow on it and the elbow and pipe end are full of water and capped with a flat plate at each end. (No, this is not homework.)
I need to determine the water weight...
I am not a CFD literate person but I have to depend on those who are as a user of CFD analysis.
However, I am looking a CFD for high pressure air entering a large vessel of a heat exchanger that goes against all of my experience (35 years of crawling around in air and flue gas ducts where there...
If someone popped into your cube/office/space and asked 'what is the installed price per foot for 500ft of 6" schedule 40 steel pipe insulated, lagged and heat traced, supported and anchored with ~10 elbows, welded construction' what would your response be knowing no more than that. This is...
Since you guys that lurk here have to debunk this snake oil myth from time to time (the fuel line magnet that is) I thought you would get a kick out of this in another forum.

I have posted a question about the subject above in the Bearing Forum, thread821-206234 that I wish to get input from the members of this forum. Please comment there rather than here.
Thanks,

I'd like to hear anyone's experience with re-babbiting bearings in the 240MM and larger range, good, bad, or ugly. I have a client that has to make a decision due to the fact of his having to turn down a generator shaft (possibly 40-50 mils) and have undersized bearings but can't wait for new...
Does anyone have any document-able or even anecdotal information about the equivalent operating hours attributable to generator starts? (Large) motor information on this topic might also be useful.
I am a ME and I am very familiar with the factor fired hour approach for combustion turbine...
Now that ethanol is replacing MTBE in as a fuel oxygenizer in gasoline in the USA, keep a close watch on your automobile's fuel filters.
Ethanol is an alcohol that will mix with water and pick it up and carry it with the gasoline. Right now all the fuel storage tanks in the system, including...

Well, I moved to Houston earlier this year. I found the above thread very helpful as I evaluated my offer.
Don't like the traffic, but I have one question. Does one ever eat at a restaurant a second time? There are so many to try out I don't see how you could ever go back...
