All, I'm down a rabbit hole trying to understand if there is a conflict between the 10/13 rule for exchanger tube rupture over pressure considerations in 521, allowing me to not install a PSV on the low pressure side, as long as the high pressure side doesn't exceed my corrected hydrotest...

Hello everyone,
Can anyone recommend a make & model of a handheld device that we can purchase to take vibration readings on process piping in the refinery that I work in? We need something that can read low enough for typical low frequency pipe vibrations, I see that some Fluke models are...
Oh geez, let's see...
"Work in a refinery"
"as a small projects engineer"
"tasked with"
Does it really sound like I own the place or make the decisions? Did I say that?
Besides, I'm asking for feedback on training, it would be helpful if we attempted to stay on topic, here. How we run our...
Thank you UAE piping, I will check that out.
As to the other two responses, does it sound like I own this refinery? Does it sound like these decisions are really up to me? Do either of you have any knowledge of the refining business at all? I work for one of the largest refiners in the...
Hi guys,
I work in a oil refinery as a small projects engineer with some reliability and some maintenance tasks also. Myself and others in my role are frequently tasked with looking at pipe vibration issues around heaters and towers and attempting to access whether things are "OK" or if...
I'm working on a leak repair on a large cooling water line and the probable solution will be to weld on a full encirclement split tee. A more experienced engineer actually told me that the fillet welds (circumferential)would "push me into the next size pipe schedule" due to them being weaker in...
Someguy79, thanks for bringing this back on topic.
I guess what I'm now confused about is what exactly total dynamic head on the pump curve is giving me in relation to the discharge pressure of my pump at some given flow rate. If I stuck a pressure gauge on the discharge piping (as typically...
This has all been a good rehash of the fundamentals and I appreciate the input. However it's got me thinking about if I've been reading pump curves correctly or not.
If the Y column is total developed head and I convert this into pressure, is this pressure my total pressure (dynamic +...
So I'm not "relying on software" as this was more of a mental exercise just for fun and any system that I design uses the dead head of a pump at it's largest impeller size for design pressure, so there is no "danger" here.
I've worked myself into a bit of a loop here.
A question came up from a younger colleague today that at first seemed a bit silly but after running a model I might see his point too. Basically, the question was if my pump discharge piping immediately sizes up say from 2" to 20" and I sized the...
Update:
I ordered and received Petroleum Refining in Nontechnical Language (as opposed to non-technical people) and it's absolutely perfect for what I needed. I'm working through it now and delighted by how clear and concise it's written but also how quickly I'm able to pick up all of the...
I'm a Mechanical Engineer who after some time away at a design firm and medical school (long story) is returning to a refinery to do small projects. I have some organic chemistry under my belt so I have a small piece of the foundation needed to understand the process in a way that I didn't...
I wanted to thank everyone that replied. I thought long and hard about the responses and I wanted to give an update for anyone that spent the time to reply or who might be browsing and read this thread.
My boss resigned and took his VP position at another design firm. I did not follow him...
@IRstuff,
That is an issue but I'm going to have that issue no matter which direction I go at this point. The only thing I can say for sure is that I didn't find maintenance at a refinery particularly interesting because I've had enough experience with that to have made up my mind.
@KENAT
I share some of those feelings about PMs also. I'm clearly torn between feeling like I need to get down in the trenches and do that stuff myself for a few years vs. learning about them from people who are doing it along the way up. I don't want to take a step backwards career wise if I...
