Weld neck flange weld to pipe dummy question

[mariolucas75]

Dear All,

I have a dummy question ....

What are the references for welding a weld neck flange to pipe - in terms to what NDT to be done and where and when?
Root pas ? subsequent passes ? What is the NDE requirements depending of fluid service ?
Code of construction is B31.3

 

[LittleInch]

B31.3 is its own code for welding and inspection, i.e. it's all in there if you look carefully.
