High Temp Cold Drawn Steel Pipe , Carbon Steel Seamless Steel Tube Long Lifespan
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, cutting, heating it to make it more pliable, then drawings it (extruding or pulling it) to make it longer and thinner. 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.
