Elbowlet on Reducing Elbow

[jtriggs]

Hello,

I am wondering if there is any code limitations or design issues with the use of an Elbowlet (elbolet) on reducing elbow fittings. My main concern is the curve of the reducing elbow would be different than that of a normal elbow, would this difference in curve cause issues when welding the elbolet to the reducing elbow? The system is being designed to CSA Z662.

Thanks in advance

If not sure, you may not want to do it per Engineering judgement.
IMO, The different curvature of the fittings may have the issue of the alignment and welding during fabrication.
