Abstract: A device for the back support of the first run weld in the automatic butt-welding of two pipes held together by the two circumferential facing sets of radial pistons of an internal connection. The connector includes a set of independent copper pads of trapezoidal shape disposed in the form of a ring and fixed, with their bases alternately inverted, on a corresponding underlying set of pad support elements idly supported by respective horizontal pins rigid with support blocks which are resiliently supported by one of said circumferential sets of radial pistons of said internal connector by means of radial thrust springs. The pads are kept resiliently and constantly pressed against each other in the manner of a ring along their inclined sides by respective horizontal thrust springs supported by said horizontal pins and acting alternately on opposite faces of said pad support elements. The trapezoidal copper pads are fixed to the respective pad support elements by screws which are inserted into the width of their bases.

Abstract: A riser termination connecting a steel riser duct to an I-tube or J-tube connecting interface of a floating unit has an upper hang off portion, lower coupling adapter, steel termination conduit having an upper conduit end rigidly connected to the upper hang off portion, and lower conduit end connected to an adjacent conduit section of the riser duct. The termination conduit extends axially slidable through the coupling adapter. A cylindrical bearing seat inside the coupling adapter defines a bearing seat diameter and axis. An annular rounded bearing body has a bearing body diameter and protrudes outward from the termination conduit inside the bearing seat, the bearing body diameter being smaller than the bearing seat diameter to provide a unilateral gap and allow relative axial sliding and rotation. The termination conduit includes a variable cross-section portion having an external diameter and wall thickness tapering from the bearing body.
