Dear Friends
I am using A53Gr B for ammonia suction at -35ºC
I know that the ASME code allow this practice as long the pressure is low and tempereature is low.
However I wish to inspect with x Ray some pipe welds to be sure .
In orther to meke the contract with the X rays company I would like to know what I should as for
I have heard I should inspect 10 % of the total welds. If one of those has a "defect" I should ask to inspect all welds.
what kind of defects?
What the code specific?
What you recomend?
I appreciate your comments
