  • Patent number: 9033372
    Abstract: A fitting assembly is provided with a first fitting component having a stepped wall surface; and a second fitting component radially spaced from the first fitting component when the fitting assembly is in a finger tight condition prior to pull-up. When the second fitting component is displaced into contact with the stepped wall surface during fitting pull-up, the stepped wall surface assists in separating the first fitting component from the second fitting component upon fitting disassembly.

  • Patent number: 9016732
    Abstract: A ferrule type, flareless fitting is provided that may optionally be pulled-up to its assembled condition by torque rather than by turns. In one embodiment, at least one fitting component includes a structure that facilitates pull-up by torque and allows the fitting to be remade. The structure may take a wide variety of different forms. Examples of fitting component structures that facilitate pull-up by torque and allow the fitting to be remade include, but are not limited to, deformable or compressible devices or structures that are configured to increase the torque required to further tighten the fitting components when the fitting is properly pulled up, resiliently deformable structures that bias a tube gripping device into engagement with a conduit when the fitting is remade to an initial pull-up position, and plastically deformable retaining structures that maintain a tube gripping device in sealing en a ement with a conduit when a fittin is disassembled.

  • Patent number: 9010810
    Abstract: Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member, a drive member, and a seal member, the drive member causing axial movement of the conduit gripping member to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member causing the seal member to form a zero clearance seal at a location that is axially spaced from the conduit gripping member. The zero clearance seal may comprise a face seal arrangement including a gasket, and the conduit gripping member may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include a sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both.

  • Patent number: 8876170
    Abstract: A drive nut for a fitting includes an interior socket centered on a central axis and configured to receive at least a rearward portion of a conduit gripping member. The socket is defined by a radial drive surface positioned to engage the conduit gripping member during pull-up, a first longitudinal surface radially outward of said drive surface and a tapered second longitudinal surface between the drive surface and the first longitudinal surface, wherein a conduit gripping device contacts the second longitudinal surface upon an initial pull-up and each remake. This geometry facilitates a greater number of available remakes by reducing lost stroke, and can provide less stroke loss for fittings pulled up by torque.

  • Patent number: 8814139
    Abstract: A seal arrangement for providing a fluid seal of an annulus between two conforming surfaces such as a stem and a bore. The seal arrangement may include a pair of packing support rings. Preferably, two pairs of the packing support rings are used in order to provide double ended or two sided axial support for the packing. The first and second support rings support a load on the packing during normal or rated temperature use, with preferably an interference fit with the stem to resist extrusion of the packing along the stem. The support rings may be nested together and comprises different materials. For example, one support ring may comprise metal and the other support ring comprise a softer material such as a polymer or elastomer. An example of a packing material is a fire resistant material. The metal support ring may be used to maintain load on the fire resistant packing in the event that the other support ring has been destroyed by fire or other cataclysmic event.

  • Publication number: 20140217321
    Abstract: A diaphragm valve with an assembly or cartridge that facilitates replacement of the diaphragm, the valve seat or both. The assembly may be a valve assembly having a diaphragm, a seat carrier and a valve seat that are combined into a discrete subassembly or cartridge for a diaphragm valve. The assembly as a discrete cartridge can be easily removed and replaced in order to change out the diaphragm or the valve seat or both. In one embodiment, the diaphragm has a perimeter that is welded to one side of the seat carrier. Flow capacity is favored by providing a gap between a seat carrier and a flow port of the valve body where the gap in part defines a flow area that is the same or greater than the flow area of the flow port. Methods for installing and replacing a valve assembly into a valve body are also disclosed.

  • Publication number: 20140034177
    Abstract: A hose for use in bio-pharmaceutical applications includes an innermost tubular layer made from a fluoropolymer material. The tubular layer has an inner, relatively smooth and pure surface that defines an opening for transfer of various media. A layer of silicone is disposed next to an outer surface of the innermost tubular layer through use of, for example, an extrusion method. The outer surface of the tubular layer may first be modified by various treatments or chemicals to facilitate the adhesion of the silicone layer thereto. The silicone material may be solid or foamed. A reinforcement layer may be disposed adjacent to an outer surface of the silicone layer. The reinforcement layer may be formed of a wire braid having gaps. An outer jacket of silicone may be attached to the reinforcement layer and to the inner silicone layer through the gaps in the reinforcement layer.
