摘要

The report discusses methods for evaluating stability of technological processes for production of pipes. It is shown that the statistical methods of quality assessment technology does not provide the required level of confidence to go to selective methods of control. It is proposed to use the comparison of smoothed periodograms for randomly selected tubes from the party. Invited to quantify the similarity of periodograms, which can be used as a measure of stability technology.
