  • Pipe Element Having Shoulder, Groove and Bead
    Publication number: 20140210206
    Abstract: A pipe element has a circumferential shoulder at one end. The shoulder has an outer diameter greater than the outer diameter of the pipe element. A groove is positioned adjacent to the shoulder. The groove has a floor surface with an outer diameter less than the outer diameter of the pipe element. A bead is positioned contiguous with the groove. The bead has an apex with an outer diameter greater than the outer diameter of the pipe element. A combination of roller tools is used to cold work pipe elements and impart a desired shape to the sidewall in one method of manufacture. In another method, a spin forming tool is revolved in an orbit of increasing diameter within the pipe element captured within a die.

  • Pipe element having shoulder, groove and bead and methods and apparatus for manufacture thereof
    Patent number: 8777277
    Abstract: A pipe element has a circumferential shoulder at one end. The shoulder has an outer diameter greater than the outer diameter of the pipe element. A groove is positioned adjacent to the shoulder. The groove has a floor surface with an outer diameter less than the outer diameter of the pipe element. A bead is positioned contiguous with the groove. The bead has an apex with an outer diameter greater than the outer diameter of the pipe element. A combination of roller tools is used to cold work pipe elements and impart a desired shape to the sidewall in one method of manufacture. In another method, a spin forming tool is revolved in an orbit of increasing diameter within the pipe element captured within a die.

  • Expansion Joint
    Publication number: 20130049354
    Abstract: An expansion joint is used to accommodate changes in length of above-ground pipe lines due to thermal expansion. A tube is surrounded by a ring attached to a sleeve. One end of the tube is attached to a pipe of the pipeline, one end of the sleeve is attached to another pipe of the pipe line. The tube and the ring and sleeve are movable axially relatively to one another when the pipe line expands or contracts linearly. A seal between the ring and the tube ensures fluid tightness of the joint.

  • Coupling having angularly oriented key surfaces
    Patent number: 8267432
    Abstract: A mechanical pipe coupling is formed of segments attached end to end to surround a central space. Each segment has arcuate keys which project toward the central space. Each key is formed of a pair of side surfaces and a mid surface between them. The mid surface is angularly oriented relative to a longitudinal axis perpendicular to a plane containing the segments. When used to couple pipe elements having grooves the angular orientation of the mid surfaces provides flexibility to the joint. A method of joining pipe elements end to end is also disclosed.
