I've worked at afew refineries that had abandoned in place pipe for over 3 decades in their pipeways, they never had a problem with it ...other then taking up space.
I've got 40+ yr.s of piping design behind me and doing back to back weld neck flanges is usually indicates a poor design. I had to do this only once when we were hooking up a 600# system to a 900# and space was limited, and that was it.
IF money is an issue then I agree with the "You Tube" approach! Actually my wife went this way and was doing very well. BUT the other point I need to stress is ...Do you know how to Draft!!?? ...In just about every way they try to teach AutoCad, it's assumed that you know how to draft, alot of...
You need to remember WHEN a P&ID is generated, and for those that don't know it's at the beginning of the project(or suppose to be). Remember that a P&ID is a SCHMATIC and is NOT used to indicate real-world piping configurations. SO how would anybody generating a P&ID know where to put flanges...
All the components of my North Arrow block are on layer "0", I've checked both the layer and view port for visibility and everything is "on" and "unfrozen", and I went into drawing order and tried to put up my north arrow on top ...to no avail. The thing that bothers me the most is this block...
I didn't use wipeout, and guys I'm not worried about "how" to put in a north arrow, but I'm wondering WHY the north arrow block works ok in some drawings and not others ...in the same file!!?
I've got a problem with AutoCAD 2013 that's driving me nuts! I have a semi large drawing file in model space, I've used the layout tabs in paper space for the drawing title block. I have about 16 tabs, one for each drawing, with a viewport for each area. Everything was going good, I'm about 90%...
You show no special symbol for welded end valves or any valve (other then type i.e ball, gate, globe, & etc.) the piping spec for any line "should" dictate what type of valve it is (flanged/weld end/screwed/SW). I agree with Kern oily on use of a SP number for any "odd-ball" items that may be...
My experience when your dealing with pipe fabrication your shooting for around 0.125" accuracy, and that's "tight"! You need to remember (or learn) that most pipe construction is done out in the field, not in some machine shop where you have the luxury of chasing everything to a the thousandths...
I'm not sure you'll find anything. My experience is that the "petroleum speak" your talking about is more "area dialect" ...what one area call something would go by another name somewhere else. Case in point, I do a far amount of work on the "up-stream" side of petroleum industry. The collection...
What type of instrumentation is on this bridle, plus size and connection type? FYI ...At 2" it's a push as to if the connection is welded or threaded ...normally.
As I had stated I work at AAPL until 89, and on the mainline they had MOV valves at all the pump stations, not sure what they had on this branch line? IF I had to guess I would think they'd carry the same philosophy at the M/L pumps stations there also. This pipeline was totally remotely...
Your connecting two 24" pipe sections together, one with sch.10 wall(older one) and the newer one with sch.20 or STD. WT. wall. AND you want to use a "wedding band"!?? ...Never heard this term, but appears to be a coupling!?? ...My answer is WHY! You have lengths of pipe connected together all...
Back in the late 1800's drawing didn't have any dimension and fabricators HAD to scale off blue prints to be able to make the "part", but the problem is obvious, they didn't get the accuracy that was required and the part became a one-off assembly ...working but not inter-changeable. Then in the...
Look up T.D. Williams company, they can tell you everything you need to know pigging a pipeline. Plus I believe they have a service to do it for you if you wish.
FYI ...Actually this section of the pipeline was not completed when I left All American Pipeline back in 8-89, it was still under construction. This pipeline was originally funded by Good Year, engineered by Marmac Engineering Services. At the time there was a real problem getting enough oil to...
WELL splitting hairs here, you can bolt up a 125# flange to a 150# flange, and 250# to a 300#. But as everyone so far has indicated, in general NO you can't. BUT pressing farther, there are times when you have a piece of equipment that has say a 300# flange, but a 150# piping system needs to...
