The experiments of tube plug drawing verified that the theoretically calculated values are identical with measured ones. Thus, this calculation model seems to be available to the engineering practice.

For many years, the Web has relied on external plug-ins to deliver features that cannot be natively supported by the Web browser, particularly in terms of 2d drawing, animation, and multimedia.

Based on analysis of the process of pipe cold-drawing plug's wear-caused failure with the Dointview of friction science, measures for surface strengthening of the said plug were made.
