<p>An apparatus for swaging an end of a tubular (22) is described as comprising a swaging head (17) for providing the swage to the end of the tubular (22). The swaging head (17) has two or more swaging formations (22A, 22B) provided thereon to permit swaging of differing diameters of tubular ends. The apparatus may comprise a stop plate (5, 9) for abutment against the other end of the tubular (22), where the swaging head (17) and the stop plate (5, 9) are movably coupled to one another. The apparatus may have a clamping device (4) for clamping the tubular (22), where the clamping device is split into at least three part-circular clamping segments (30) which clamp around the outer circumference of the tubular to permit it to be swaged. The clamping device (4) may have a plurality of teeth (35) for gripping the outer surface of the tubular (22), and a plurality of grooves (36) formed between the teeth (35). The gripping surface of each tooth (35) is substantially parallel to the longitudinal axis of the tubular (2) to be gripped.</p> |
