a.       For the B type, the maximum deviation of any thread height can exceed the allowable deviation specified in the table, but it should not exceed the allowable deviation of 0.08mm, and the average height of all threads should be in line with the given deviation range.

b.       The rating is based on the axis of the pipe.
