  • Weld test tool
    Patent number: 5263362
    Abstract: A pair of semcircular jaws seal against the outer periphery of a pipe adjacent a butt weld joint in the pipe. The jaws have annular pressure rims that apply mechanical pressure against the outer surface of the pipe; and the jaws provide an annular manifold cavity between the pressure rims through which high gas pressure is applied against the joint and adjacent areas of the pipe, all for the purpose of slightly deforming the pipe and opening up any fissure that may exist by reason of an imperfect joint. In a modified form, a cylindrical shroud carries an annulus of balls for supporting against and applying deforming pressure on side portions of the pipe as the shroud is rotated around the pipe.
