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