The method for making ASTM A106 cold-drawn seamless pipes involves taking a round "billet" or bar of steel and boring it in the center,turning it,cutting it,heating it to make it more pliable,then "drawing" it (extruding or pulling it) to make it a longer and thinner pipe. As the pipe cools,"cold working" begins.Cold working involves pulling the pipe over a stationary die and a mandrel.This increases the pipe's hardness and improves its surface condition and grain structure while reducing the pipe to the desired size and thickness,according to Michigan Seamless Pipe.
