Dear group,
Please if you could analyzed the attached image.
It´s pipeline B31.8.
Constructor at first time, welded tube-flanged joint. Then realized that its necessary have an instrument as showed.
The ask is there´re some restrictions for minimal distance between weld joint and derivation in pipe.
Please if you could give some reference in design code.
Thanks in advance
