ABSTRACT:
The amount of materials in a piece of tubular stock is measured before the stock enters a stretch-reducing rolling mill and the mill is so controlled that the finished tube can be cut into lengths without the occurrence of overlengths or underlengths. In the case of a seamless tube, the piece of tubular stock is weighed and the flying means which cut the finished tube are so controlled that the lengths of all the finished pieces lie within prescribed tolerances so that there is no waste, other than the usual cropped ends. In the case of welded tube, the thickness of the strip material from which the tube is made can be welded, and the welded tubular stock can be cut to a suitable length to ensure that no overlengths or underlengths are obtained after the stretch-reducing and cutting of the finished tube into pieces of prescribed length, within tolerance limits.
