  • Method and apparatus for cutting circular or oval pipes
    Patent number: 4541316
    Abstract: Cutting tools 12 are individually connected in common to rollers 2b supporting a rotationally driven tube T to be cut. The tools and rollers are paired mechanically such that the cutting edge of each tool and the tangent point G between the associated roller and the surface of the tube lie in the same radial plane passing through the longitudinal axis T--T of the tube. This arrangement makes it possible to maintain constant the penetration depth of the cutting tools into the surface of the tube even if the tube is oval or elliptical.

  • Ductile cast iron pipe having constricted end casing
    Patent number: 4435894
    Abstract: The invention provides a pipe or similar tubular member of ductile cast iron having an end casing. The thin walled casing has a curved profile at its entrance divided into two sections, of which one is formed by centrifugal casting, whereas the other, of lesser curvature, is made by hot or cold forming with a simultaneous axial compression and a radial bending directed towards the axis of the pipe. The invention is useful for forming fluid tight seals in pipelines using radial compression packings.

  • Device for rotatably gripping a cylindrical piece
    Patent number: 4386544
    Abstract: A sleeve grip for a pipe is radially expandable by axial compression from a bolt-nut system. One of the elements 8 of the bolt-nut system 13 is connected to a bidirectional drive motor 23 inducing rotation in the cylindrical pipe 2 and the other element 24 to the movable disc 25 of a brake 14. Thus, by simple tightening or slackening of the brake 14 and activation of the motor 23 inducing rotation in the pipe, it may be held by the expandable sleeve grip 12 or released.
