I am not expecting a definitive answer to the following question, I simply want some recommendations concerning preventative maintenance on high pressure oil skid fittings.
I am writing a recommendation for a customer concerning some fittings that see on average 1100 psi in a clean service. I...
I am in a bit of a pickle, frustrated and ill-equipped with UL and ETL standard knowledge to deal with this situation. I am hoping someone here has a deeper understanding of these certifying bodies and can help explain some things to me.
Back story: Small repair shop start-up, part of a larger...
I am hoping to find a recommendation from some of you more versed in metallurgy for a quick reference book relating primarily to steels. I am pretty un-seasoned when it comes to comparing one composition of a steel versus another from, and would like to learn more "tribal knowledge," if that...
I am researching the differences in Rockwell numbers between 316 ss and 2205 Duplex (I am not a metallurgist, so bear with me :) ).
I understand the inherent advantages and disadvantages of 2205 Duplex vs 316 ss (austenite and ferrite structures and what that implies) but the range of Rockwell...
I have a shaft that has had 4 flats cut into it. I want to know the flat width, but do not have access to the shaft. I know there must be a way to do this calculation, but I cannot think of it.
Here is the data I have:
- Shaft D: 3.199", giving an OD of 10.04486"
- Flat depth: .021
- Total of...
Just looking for brainstorming:
What could cause a dual pressurized set of gas seals on a split case pump (7 impellers) to fail the seals, touch off on only one part of the gland plate (shaft rub of about 90 - 180 degrees) and shear off some dog-point set screws. (3 failures in less than a...
I am supporting a failure analysis on a set of 4 dog head set screws that failed on a mechanical seal. I am trying to determine the minimum point at which shear failure could have occurred based on the materials, cross section etc. Here is the write up I have performed thus far, do these...
