Once you choose an ANSI B16.9 branch connection to meet the piping spec
requirements you should be alright, otherwise, for example if you choose to
replace a 4X2 reducing Tee with a Stub in, then to be code compliant you
need to do a calc to check if the branch connection requires a reinforcing
pad or not to meet the design conditions.

Subject: Branch connection
Dear Pipers,
As per piping material spec. for flowlines in a wellhead platform, we
use
branch fitting 4"X2" unequal tee.
Our contractor like to change to 4"X2" weldolet instead of unequal
tee which
is out of spec.
Can anybody tell me how we can accept weldolet instead of unequal tee?
What is the calculation to justify weldolet is acceptable?
What's the references to calculations? Like code? Std? Books?....
Cheers
Prakash
