ABSTRACT:
A dual clamp assembly consisting of two U-shaped clamps and a welded joint autogenously interconnecting each of the U-shaped clamps forming a single unitary assembly for joining two pipes telescopically fitted into one another to form a lap joint therebetween with each of the U-shaped clamps comprising a U-bolt portion having a horseshoe configuration with open ends extending therefrom and a cradle portion having openings into which the open ends of the U-bolt portion are removably fitted. Each cradle portion of each clamp is spaced apart solely by the welded joint allowing each clamp to be mounted to each of the pipes on opposite sides of the lap joint with the welded joint positioned therebetween and in contact with the lap joint so as to prevent said pipes from being pulled apart.
