  • Patent number: 10408370
    Abstract: A valve and coupling for joining pipe elements has a valve body captured in a central space defined by a plurality of coupling segments attached to one another end to end. The inner surface of the valve body defines a bore. A liner on the inner surface surrounds the bore and forms a seal with a valve closing member. Circumferentially arranged projections on the segments engage and center the valve body within the central space. The liner has lobes that extend axially in opposite directions. The lobes are compressed between the segments and the pipe elements to form a fluid tight seal when connection members are tightened to draw the segments toward the central space and into engagement with the pipe elements.

  • Patent number: 10408368
    Abstract: A mechanical coupling for joining pipe elements has a seal. The seal has sealing surfaces with one or more projections that form closable leak paths between the coupling and pipe elements being joined. The leak paths close when the coupling is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings can be discovered during pressure testing and before service pressure is applied.

  • Patent number: 10369609
    Abstract: An inner roller used for roll forming pipe elements has a flange extending radially from a body. The flange has a surface divided into annular surface portions. The surface portions have orientation angles measured relatively to the axis of rotation of the inner roller. The orientation angles of surface portions farther from the body have greater orientation angles than the surface portions nearer to the body to mitigate adverse frictional effects between the pipe element and the flange during roll forming.

  • Patent number: 10371295
    Abstract: A pipe fitting has housing portions attached in spaced relation to define non-coaxial receptacles that receive pipe elements. The housing portions are supported on split rings received within grooves in each housing portion. The housing portions are supported in spaced relation in a preassembled state to permit insertion of pipe elements into the receptacles without disassembly of the fitting. The grooves in the housing portions have a floor surface with three surface portions. Two of the surface portions on each groove of each housing portion engage the split rings when the housing portions are supported in spaced relation.

  • Patent number: 10359267
    Abstract: A behavior inspection apparatus includes: a first measurement tool group including a set of first measurement tools each of which measures a first distance change amount that is a change amount of a distance between a first pipe position in the first pipe and a first reference position of a sleeve of the extensible flexible pipe joint; and a second measurement tool group including a set of second measurement tools each of which measures a second distance change amount that is a change amount of a distance between a second pipe poison in the second pipe and a second reference position of the sleeve. The first and second measurement tools are arranged at different positions in a circumferential direction of the sleeve. Displacement positions of the first and second pipes with respect to the joint are computed based on the measurement data by the first and second measurement tool groups.

  • Patent number: 10245631
    Abstract: A roller set for roll forming pipe elements has an outer roller that engages the pipe element at three points to prevent teetering of the pipe element. Inner and outer rollers cooperate to form pipe elements having a projection engageable by keys of mechanical couplings, the projection extending beyond the outer surface of the pipe element and increasing the pressure and bending performance of the combination pipe elements and coupling.

  • Patent number: 10189070
    Abstract: A roller for engaging an outer surface of a pipe element during roll forming has a perimeter region defined by three faces. A channel is positioned in one of the faces. The channel extends circumferentially around the perimeter region and provides a void space that reduces the contact area between the face and the side surface of a circumferential groove formed in the pipe element during roll forming. The reduced contact area reduces frictional heating of the pipe and roller as well as the tendency of the roller to slip relative to the floor surface of the groove due to axial force engendered when an asymmetrical groove is formed.

  • Patent number: 10190707
    Abstract: Pipe elements have circumferential grooves. The grooves have a first side surface contiguous with a first floor surface. The first side surface and the first floor surface together subtend a first 90° circular arc when viewed in cross section. The grooves also have a second side surface contiguous with a second floor surface. The second side surface is in spaced relation to and in facing relation with the first side surface. The second side surface and the second floor surface together subtend a second 90° circular arc when viewed in cross section. A third floor surface is contiguous with both the first and second floor surfaces and is a flat surface. A coupling used to connect the pipe elements has arcuate projections which engage the grooves of the pipe elements. The arcuate projections have a semi-circular cross section. Relief grooves are positioned adjacent to each arcuate projection.

  • Patent number: 10161547
    Abstract: A combination of roller tools is used to cold work a pipe element and impart a desired shape to the sidewall. The roller tools are movably mounted on a frame. Segments of the roller tools align with one another during operation. The roller tools are used in a method of roll forming wherein the sidewall of the pipe element is compressed between the rollers.
