surface roughness on tube hole?
surface roughness on tube hole?
(OP)
Dear Sirs,
I can not find on ASME either on TEMA a reference about the surface roughness tolerances on a tube hole of a tube-sheet.
I mean, I would except something like: tube-hole OD=19mm then surface roughness max. 5micron.
It seems very strange to me since tube-hole surface roughness is very important for a tight sealed expanded joint.
Please advise.
Regards,
A.K

roughness in good as long as it is all circumferential.
