A while back I was told threading a SCH40 pipe "makes it SCH20 at the threads". During a conversation today with a friend I was contemplating this rule of thumb and wondering if it's true? Where would I look up information on how much metal is removed at the threads, what is the resulting wall...
LittleInch,
Excellent points, and a star for you of course. We've got one other install with a similar setup, boosters in the middle of a pipeline from point A to point B. However there isn't nearly as drastic a difference in elevations. This company uses very little in the way of automatic...
miningman, telling me to educate myself... In a thread I started, asking questions... I'm wondering what you thought I was trying to do? Maybe you missed the first post. Scroll up perhaps? If you have some knowledge on booster pump stations, this is your chance to shine!
Artisi, not sure...
There's pumps at either end. This pipeline is going to make the connection between the two sets of pumps.
We could flow from one end to the other with no booster. We can't make the *rate* we need, however. We'd be much, much lower than desired.
No graphs at the moment, sorry.
Just...
When modeling pipelines, does one assume that your process simulator will provide an accurate (as accurate as your compositional input and operating parameters, of course) representation of gas breakout in the system, or does one use a rule-of-thumb or fudge factor to add vapor to determine the...
Something like that. Even more fun is the system needs to be bi-directional, so we'll be pumping either way through either line.
Starting and stopping the system would be simply shutting down the pumps at the source and destination. My people insist on these things being manned, so someone...
Working on a project to install two pipelines, freshwater and produced water, going 10 miles from one atmospheric pit to another. They don't mix if course. It has been determined that a booster pump station must be installed at a midpoint which also happens to be at the bottom of a...
I was wondering if y'all had any rules of thumb or metrics for tracking construction project on upstream/midstream type construction projects. Do you total up all the pipe weld inches and track completed vs total? Linear feet of pipe laid and completed? Vessels set? There's a lot of things...
LittleInch - I'm expecting to see > 95% water at max rates, and probably > 99% water at minimum rates.
IFRs, would you care to share the vendor from whom you purchased?
Seems like y'all are up to speed on what a gun barrel is (or gunbarrel, some folks spell it both ways). I think I've heard the term wash tank before, although I feel like that implies something different. It is essentially a large separator, operated at a very low pressure, to remove a little...
What defines the capacity of a gun barrel? Is it simply a very large (for the most part) 2-phase liquid/liquid vertical separator?
Must the gun barrel be taller than the tanks it feeds into, or must the level simply be higher to avoid having to pump? I think this is pretty obvious but never...
Anyone have a step-by-step method for obtaining elevation data from a Google Earth .kmz file? I'm in the process of reviewing a pipeline route (probably going to be about 10 miles long) through some back-country in Texas. Elevation changes are on the order of +/- 200 feet at the most extreme...
(I apologize for the cross post, I posted in Gas Distribution but I thought after the fact this might be a better forum?)
Forgive my ignorance here. I got asked a question that I had not considered before so I don't have a good answer at the moment. Hope y'all can help.
Why is it we generally...
