Abstract

The device is used for repairing broken or cracked tubes. The crack (2) is repaired with a heated driver (3) made by sheet metal wound into a helical roll. The driver can be made to contract either by preheating or by mandrel expansion of the tube. The driver (3) may either be wound on the spot around the tube, or previously would and applied in a similar way to a key on a keying or a spring round a rod.An insert (4) can be placed on the tube to cover the crack (2), and may be a single piece or a spiral sleeve. The band used to make the helix is broad enough to completely seal the crack
