Good morning, I've come across an issue in the field where a welder used a 1" sw 3000# elbolet in place of a 1" sw 3000# latrolet on a straight run of piping. Besides the obvious flow restrictions (which in this case are very negligble), I haven't found anything in B31.3 that says this can't...

Pardon me, they did use a LR elbow. A spec blind would have been a better solution.
