  • Roller set and pipe elements
    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.

  • Coupling and circumferential groove shape
    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.

  • Roller for roll forming
    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.

  • Device and method for forming pipe elements
    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.

  • Sprinkler adapter and pipe plug
    Patent number: 10156312
    Abstract: An adapter for joining a sprinkler to a pipe element has a body with outer flat surfaces and grooves that receive seals. A plug for sealing a pipe element has a cylindrical body with a circumferential groove which receives seals. Both the adapter and the plug fit within the pipe element and are secured and sealed by a deformation formed in the pipe element by a circumferential groove. The deformation mechanically engages the grooves in the body of the adapter and the plug.

  • Flexible dry sprinkler
    Patent number: 10143872
    Abstract: A fire sprinkler head (12) has a valve (42) with an X-brace latch (54), and includes a flexible conduit (14). A sprinkler nozzle (16) is secured to a first end of the flexible conduit (14). The sprinkler nozzle (16) includes a first fitting (28), a sprinkler orifice (20) and fusible element (22). A second fitting (40) is secured to the second end of the flexible conduit (14) and includes the valve (42). The valve (42) has a valve element (44) which is moveable from a latched position to an unlatched position. A flexible link (56) extends from the sprinkler nozzle (16) to the X-brace valve latch (54). Breaking of the fusible element (22) releases the flexible link (56) to move from the latched position to the unlatched position, releasing the valve (42) for flow there-through.

  • Split ring coupling
    Patent number: 10100957
    Abstract: A pipe coupling has segments attached end to end to define a central space that receives pipe elements inserted between the segments. The segments are supported on split rings received within grooves in each segment. The segments are supported in spaced relation in a preassembled state to permit insertion without disassembly of the coupling. The grooves in the segments have a floor surface with three surface portions. Two of the surface portions on each groove of each segment engage the split rings when the segments are supported in spaced relation.

  • Seal with lip projections
    Patent number: 10036494
    Abstract: Seals for mechanical couplings and fittings have sealing surfaces with one or more projections that form closable leak paths between the coupling or fitting and pipe elements being joined. The leak paths close when the coupling or fitting is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings and fittings can be discovered during pressure testing and before service pressure is applied.

  • Fittings having arcuate stiffness ribs
    Patent number: 10024467
    Abstract: Fittings, including elbow fittings and Tee fittings have bodies that surround a central space and define openings to receive pipe elements. Ribs surround the openings, and gaps are positioned between the ribs to permit deformation of the body when ends of the body in facing relation are brought together. The body may be formed of two housings or unitary in construction. The ribs may be grooved to accommodate toothed retainer rings providing mechanical engagement with pipe elements. The ribs have surfaces with radii of curvature that, when the ribs are undeformed, are substantially equal to the radii of curvature of the pipe elements they engage.
