Daniel,
the welds inside the plant will have to be to B31.3, which in reality is not a whole lot different from 1104, just tell your welders to be extra careful, there is less LOP/LOF allowed in B31.3,

Dear all,
We have to build two 10" pipelines according Api 1104- one bitumen in
concrete trench and other by gas oil (buried)... we have 10% RT
.....but a part of lines are inside plant (around 30 meters -15
welds.....)
how we will inspect RT the welds inside plant ...according API or B31.3?
Also along the bitumen piping system and pipeline we have 1" hot oil
traced line .....
What kind of inspection is recommended? RT%? PT%? Visual?
Thanks
Daniel
