Dear All,
The bridge is designed accordance with D1.5; there are many pile have heavy wall thickness and produced by rolling and welding girth and longidintual seam. Pile manufacturer says that UT inspection should be accordance with D1.5. However, it is not a code for tubular structure. However, D1.1 Include the tubular structure and its inspection topics. Manufacturer says the piles are not tubular structure because piles have to allow to reach to inner side of its structure? I want to know that is the pile tubular or not and which code should we use for UT inspection?
Thanks for your time
