Waviness and Flatness in Shell
Waviness and Flatness in Shell
(OP)
Hello I have a doubt about how to measure and analyze the flatness and waviness tolerance in the shell, API 650 12th states this in the paragraph 7.5.2 a), pointing that we should use ASTM A6, A20 or A480 for checking the tolerance for out plumbness in one shell course.
My main doubt it's how we measure, we just measure points in the shell course up and down and take the difference of the inner diameter of the tank, and then compare with the tables in those norms?
