I'm trying to size a fluid buffer or surge protector for a small hard piped manifold which has a 1500psi output regulator and a number of small valves.
We've experienced (in the past) regulator jacking (rapid open/close cycle) when there isn't enough fluid capacitance in the circuit between the...
I'm doing some reading on the TMI incident.
There were human factors at play, but a critical pilot operated relief valve was also faulted. I've seen this noted in many reports (Rogovin report) as well as all over the net and unfortunately also Wikipedia which everyone references.
What I don't...
For ASTM A240 thick, hot rolled, annealed plate UNS S31603 (316L)
What material issues may cause a properly run ASTM E8 to report an estimated Elastic Modulus (Youngs) significantly lower than expected? (28-31Mpsi)
What testing issues may cause a good piece of material to show a very low...
This is more of a survey than a specific question.
I'm curious about preferred material selection for subsea use. In my experience most companies have a small pallet of approved choices for various applications. This pallet is developed over the course of multiple projects, with input from...
I'm looking for input from people who use or have used laser cladding to reclaim or rebuild parts. I have a large high dollar 316L weldment with some sealing bores on it. During final machining or testing the tolerances were blown out of spec.
We want to add 316 or something even better perhaps...
I believe I may have a residual stress problem with a forging which becomes apparent only after stress is applied to it and it yields more than anticipated. The material is Nitronic 60 (UNS S21800). Standard practice after forging is solution anneal at 1850°F for a few hours then rapid quench...
I'm looking for some magnetic stainless steel which could be used subsea (5000-15000ft) indefinitely. 430 for example is common but is worse with regard to seawater corrosion than 304.
I'm familiar with 446 which is a very high chromium flavor 400. I'm looking for others. Bonus points for a...
