Dimensions of Elbows
Dimensions of Elbows
(OP)
Ive done a search and cannot find any standard for dimensions of forged elbows,tees, etc. I am thinking this is in ASME B16.11 but cant find that specification either (section 11?) I was refered to b16.9~b16.28 from a sa-234 spec under dimensions. Got lost from there.
The reason I am asking is my firm is looking into providing a service of monitoring FAC in powerboilers (among other things) and it would help greatly to be able to establish a baseline. From what I gather, there is no documented standardization of od dimensions of elbows and tees from manufacture to manufacture as there is for pipe?
Any help with this would be appreciated

Dimensions of Forged fittings are in ASME B16.11 (table 5), which included both end to end dimensions, OD and minimum wall thicknesses.
SA-234 is a spec for Wrought fittings, not forged fittings. Their dimensions are in ASME B16.9. OD of these fittings are same as that of pipe per ASME B36.10M.

I was hoping to find a standard for this. The answer from the qc manager of mill was it is dependent on the manufactures ability to form. This thickness could vary as much as 20% from manufacturer to manufacture.
The answer to my question is that NO, you cannot determine the rate of internal corrosion/fac of formed fittings without first having a set of baseline measurements because you dont know exactly what the thickness is in the first place. Unlike pipe that has standard of thickness consistent the full length.

Also, seamless pipe has a mill tolerance of 12.5 percent to accomodate the "wandering" of the tools (mandel and dies) during manufacture. Seam welded pipe will have the same standard thickness tolerance as the plate from which it is made.
