pipe fitting dimensions
(OP)
Can anyone tell me the dimensions of a 6", 90 degree, socket weld pipe fitting? Or advise where this info can be found? Thanks

but why have it custom made and cost u an arm and leg when a bw elbow would also probably do the job.

Perhaps a more important issue for non-standard fittings would be Code pressure design.
I you use a standard B16.11 (only up to NPS 4) socket welding fitting, the fitting is prequalified for the pressure/temperature class (assume the class is chosen correctly). If you use a B16.9 butt welding fitting of a certain schedule, it is similarly prequalified for the matching pipe schedule. Sometimes we take this for granted.
If you use a non-standard fitting in a B31.3 piping system, it must be qualified for pressure design to the requirement$ of paragraph 304.7.2 and thi$ colul get very expen$ive.

precautinoary note. sw larger than dn 50 (nps 2) shall not be used under severe cyclic condition.
even if this is a one-off application, it hardly justify the cost and effort. propabaly u may have to make adjustment also to the wps (pipe range). but if youre involve in piping layout design, normally u would not want the designer to check out every now and then whether the service is cyclic condition or not, so u put a cap - its a no no for 2 inches. a fillet all around weld joint on a 4 inch or above line would probably require qualififcation - not a full penetration.
