    摘要: A pipe clamp for affixing to a pipe subjected to bending to minimize fatigue for a butt weld in the pipe. The pipe clamp includes an inside clamp segment and an outside clamp segment each having a semi-cylindrical shape, a first end and a second end. An inside surface of the inside clamp segment is substantially smooth for permitting slippage of an outside surface of the pipe with respect to the inside surface of the clamp segment. The outside clamp segment has an inside surface that defines a friction element. The friction element is for gripping an outside surface of the pipe to which the outside clamp segment is affixed. A clamp mechanism is provided for securing the inside clamp segment to the outside clamp segment.

    摘要: A method for joining well tubulars by a friction welding technique comprises the steps of lowering a first tubular element (3) partly into a well, positioning a welding ring (5) on top of this element (3), hoisting a second element (4) to a substantially vertical position above the welding ring (5) and rotating the welding ring (5) relative to the tubular elements (3 and 4) while deforming the welding ring (5) in radial sense such that sufficient frictional heat is generated to create a friction weld between the welding ring (5) and the tubular elements (3 and 4).
    A friction welding device for use in the method comprises means for fixing the tubular elements (3 and 4) in a substantially vertical and aligned position near the wellhead and means for rotating the welding ring (5) relative to the tubular elements (3 and 4).
