Why include conditions on plate or coil quality when operating at a higher alternative MAOP?
All steel pipe is made from either plates or coils. If these steel plates or coils are of superior quality, then the pipe will also be of superior quality. Assuring quality requires that the mill that made the plate or coil had an inspection and quality control program to limit variation and to improve the quality of its final product the plate and/or coil. The condition simply requires that operators verify that such a program was in place at the mill.
