Has anyone else noted a change in the quality control of these type nuts ('2H', ASMT A194) over the past couple of years?
In this ever-changing world of quality control and quality assurance, we have started digging into this topic. It all started with several field failures when the nuts were...
I have inherited the following situation with a heat exchanger:
Condensate (boiler feed water) on the tube side which is considered "pure water" with little or no contaminants. It is at pH of 8.3 and Fe (iron) concentrations are well below ASME standards.
Treated Water (from the reverse...
We have a tank that the documentation (dating back to the early 1940's) states there is some part of it made with "A-70 FBX" steel. I understand FBX means FIREBOX. However, none of my resources go back far enough to capture what the A-70 spec entails. I'm assuming a carbon steel.
Does anyone...
Does anyone have information they could share on the tensile properties (yield strengths) and other mechanical properties for 9Cr low alloy carbon steel (in particular SA 335-P9) at elevated temperature (in excess of 1000°F)?
Thanks!

Does anyone have information regarding the use of Admiralty Brass tubing bundles in cooling water service (tube side @ 100 deg F) and naphtha service (shell side @ 150-300 deg F)?
A history of failures, fouling concerns, etc. is what I'm interested in.
Thanks
Does anyone know of an existing reference that would help one determine whether or not a piping system (within a petroleum refinery) would need a hydrogen bakeout?
Lengthy references are okay, but I've been asked to develop a SHORT and SUCCINT methodology to help our planners.
Thanks!
I'm just wondering if anyone else is in the review process of RP 571. It was just thrown at me prior to Christmas and I have no idea on the timeline for completion. Can anyone fill me in on the subject?
Thanks!
