Are pump casings really that sensitive to API reactive loads - or is someone pulling my leg?
do you use the appendix F : criteria for piping design
1 - If a pipe lifts off its seat, and there is no exceedence of stress - is that really a problem? What range of tolerances are...
Thanks to all these friends that answered me about this surprising problem, that nobody can give me a detailed drawing of a major fitting that obviously will be in our systems the first element that will creep !!!!! The fitting have been bought by a major contractor that work with various...
thanks for your answers, but I was not precise: I want to know the true thicknesses along a tee, not the thickness of the straight acc. pipe.
the thicknesses can be up to 1.5 the pipe thickness, and it is a manugacturer knowledge, but if it is a "standard" tee, I think that it will not be a...
URGENT
We erect a lot of "standard" tees in our HRSG but never received detailed thicknesses. We urgently need the various thickness of the 24" sch 40 tee (fitting) to evaluate by ourself the conformity of our tees.
thanks
1 - On a P91 header (T=1063F P= 2090 psi)we need access for radiographic inspection. The proposed gamma plug, directly screwed in the thickness of the header, is a 1" plug acc to spec SA182 F22 class 3.
The header is 12" x 1.5"
Do you know problems about F22 screwed plug in P91 header?
2 - Are...
we receive P91 elbows Brinnel Hardness 134-137. Straight pipe has HB 184-232.
Is this HB acceptable for 24" sch 40 elbow designed to 20 years , temperature 532 oC and pressure 36 bar ?
On what others parameters this impact?
What to do to correct this?
