Hello.
I am not a drafter. I’m an engineer and project manager in the natural gas industry and have been for 25 years.
I am struggling with an employer, software, and piping inaccuracies. I have a designer who is relatively inexperienced who started out piping in Plant3D and now in Revit...
Well, a major manufacturer of ILI tools said I’m fine with 3D fittings and 5D ISO bends are overkill, for my situation.
Now I’m wondering if I can get segmentable 3D fittings to replace even everything easily cold bent, just to control ovality and wall thickness. I have a couple 17 degree and...
Not sure why, but I cannot reply to specific posts.
My understanding is that elbows are not readily available beyond 1.5D, hence discussion of bends.
I see a comment about avoiding induction bends, but how does one specify with any accuracy that a contractor produces correctly constructed cold...
I have a feeling I know the answer, but has there ever been a go-by data sheet that shows the minimum from ISO 15590 to get the bends ordered correctly?
I was planning on resorting to data sheets. I only have 4-5 bends needed for this project. I have informed my protege, who knows nothing at a...
I really appreciate the quick response. This gives me some homework and a place to start.
Is it as simple as saying if my calculated design pressure is, say, 3,000 PSIG, that my actual design pressure when using 5D fittings will be 3,000 * .92?
Also, is a bend typically a BOM part, or is it...
Hi. I have searched and read through multiple threads here about pigging and proper fitting radii. I even read through the Industrial Pigging Technology book. I have 20 years of experience in natural gas engineering and project management in midstream, transmission, distribution, and...
Hello.
In all my years of gas engineering I have never had a relief valve in close proximity to powerlines. I am designing a new natural gas regulator station at the end of a new pipeline and the preferred location is adjacent to an industrial park road ROW with powerlines just inside the ROW...
