Jul 02, 2018 · Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order.Large Diameter Steel Pipe - Things You Must Know before For LSAW and SSAW large steel pipe:From 508 mm 20 inch to 2540 mm 100 inch. For large diameter seamless pipe also refer to the pipe that more than 16 inch or 20 inch. Since the pipe larger than these sizes, will not be manufactured only by hot rolling, an additional process hot expanding will be applied.
