isolation valve. The owner should have a word on this as well.
Normally you should be fine if you do API 1104 as it is very similar to
ASME B31.3.

Subject: [MW:2975] Pipeline rt inspection
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
