RE: 90.08 degree elbow?

For but weld elbows, the end preparation of both mating flanges & pipes are slightly grinded/ chamfered to get the desired angle and slope.

For socket weld fittings, there is a minor gap between pipe and socket and other thing is that socket fittings are used for small bore pipings which are flexible enough and the slope can be adjusted in supporting/clamping the pipe length for long stretch run pipes.

Dear all, I'm designing a blow down line, it is from low level to piperack on high level, there will be a 90 elblow between the riser and sloping header on the piperack, in Rebis this elbow is 90.08 degree (slope 2" per 100'), of course there is no such elbow. my question is: in the real world, can this be done? if so how they do it?

simalar question, in real world, how do they build sloping line with socket weld fitting? of course they can't cut socketweld elbow.

please help
