Max,
The standards to which the pipes are made (A 53, A 106, API 5L, etc.) allow an out of roundness of 1%. This means nothing in a 2 inches pipe, but means a great deal in a 30 inches pipe, as the one we're talking about. As I said in my first posting, it means that the out of roundness may be 7,6 millimeters, more than 1/4 of an inch.
If scirocco's 30 inches pipe shows an out of roundness of, say, 7,5 millimeters, it can not be rejected because it is within standard. What he (scirocco) should do is to employ the usual strongbacks and wedges to match the two pipe ends, and then weld them.
