otherwise how we can understand the leakage? If code or client's spec
doesn't require leak test, why we have to do? Of course it is better
to do. Like better to do 100% RT, but in case of 10% requirement, we
accept balance 90% on the basis of 10%. Same way code considers that
the welding between run and branch pipes are OK. More over leaks may
be also from vent holes.
SS wrote that during hydrotest of main line, we can also find leakage
in RF pad. I think this is completely wrong, otherwise we have to
change the fitter, welder and welding inspector immediately.
