Re: Big Elbows

Thanks. With these upcoming large pipe sizes and traditionally-recommended upstream requirements for flowmeters, mitred elbows can cause problems if SR elbow-mounted annubars are specified by process.

Given such large pipe sizes, everything seems to have to be custom-calculated since there are no standard fittings above 48".
