Abstract: New experimental data on explosion-assisted blockage of gas- or water-filled steel pipelines of various standard sizes with a 5–7% relative wall thickness and diameters up to 424 mm are reported. The data show a considerable potential of the method. It is shown that a twentyfold change in the pipeline dimensions, at a impactor-plate velocity of $\approx$ 200 m/sec, induces no specific features into the pipeline blockage behavior. In this case, the explosive consumption increases from 3 g to 3.5 kg, with no spalling or fractionation of the impactor-plate material and screens observed.

Keywords: explosives, pipeline blockage, gases and liquids.
