摘要： A clamping connector that can be remotely actuated and locked which is particularly useful in subsea applications for attaching subsea Christmas trees to marine wellheads. The clamping connector includes clamp halves linked by a locking stem. The locking stem is forced into a pre-stressed state by moving the locking stem from a first relaxed to a second pre-stressed position and retained in the second pre-stressed position by a locking collet. A locking collet through which the locking stem extends is moved from a first unlocked position to a second locked position wedged between the locking stem and one or the other of the clamp halves. When the locking collet is in the second locked position, it resists movement of the locking stem from the second pre-stressed position to the first relaxed position. The locking collet is then locked in the second locked position. The clamping connector of the present invention is characterized by a minimal height which is particularly advantageous over prior clamping connectors.

摘要： A tubular joint adapted to connect a pair of pipes is formed by a joint body made of a synthetic resin having a pair of connection ports integrally formed on respective sides thereof. An engaging groove is formed around an axial line on an outside circumferential surface of each of the connection ports, and a synthetic resin-made fall-out preventing member is fixed at an end portion of each of the connection ports. An outside cylindrical portion of each of the fall-out preventing members has a tapered surface adapted to enable the fall-out preventing members to be press-fitted onto the respective connection ports, and includes a plurality of engaging portions that are engaged with the engaging groove formed around the axial line on the outside circumferential surface of each of the connection ports as the fall-out preventing members are press-fitted thereon. And an inside cylindrical portion of each of the fall-out preventing members extends toward a center of the connection ports in an inclined manner, and includes a plurality of fall-out stoppers whose tip ends are shaped so as to be engaged in a groove portion formed around an axial line on the outside circumferential surface of the respective pipes to be connected as the pipes are inserted and fitted in the connection ports.

摘要： A flange protector for protecting opposing flanges of a pipe joint from corrosion and leakage. The flange protector is comprised of a transparent, flexible, elastomeric band for wrapping around the periphery of the opposing pipe flanges of the pipe joint. The band has metal straps that support a fastener for pulling the ends of the band together tightly around the pipe flanges and lubrication inserts for injecting a lubricant through the transparent band to the surfaces of the flanges. The transparent band is sufficiently clear so as to allow visualization of the amount of the lubricant present at the flanged pipe joint and the presence of any corrosion of the flange surfaces without the removal of the flange protector from the flanged pipe joint.

摘要： Each of the semi-circular coupling segments has pipe fastening parts. One pipe fastening part has a protrusion to be in contact with the side surface of the circumferential groove of one pipe nearer to the end of the pipe in one of the end sections thereof with respect to a circumferential direction, and a protrusion to be in contact with the side surface of the circumferential groove of the pipe farther from the end of the pipe in the other end section thereof with respect to the circumferential direction. The other pipe fastening part has a protrusion to be in contact with the side surface of the circumferential groove of the pipe farther from the end of the pipe in one of the end sections thereof with respect to the circumferential direction, and a protrusion to be in contact with the side surface of the circumferential groove of the pipe nearer to the end of the pipe in the other end section thereof with respect to the circumferential direction.

摘要： A pipe coupling axially connects two pipes having a smooth outer surface. The pipe coupling includes a first split circular ring and a second split circular ring. The first and the second split circular rings are made from a metal strip. Each of the strips have a radially inner edge surrounding the ends of the pipes. A plurality of teeth are disposed at the radially inner edge of the strips. The teeth are disposed in the plane of the respective rings. A free end of the tooth penetrates into the pipe when the coupling is in the clamped position. The teeth extend at an angle relative to a longitudinal axis of the pipes. A side of each of the teeth facing toward the pipe inserted in the coupling have, adjacent to the free end of the tooth, at least one indentation. The indentation displaces the material of the tooth on the side of the tooth in the direction toward the free end of the tooth.

摘要： A pass-through dual containment fitting that protectively seals a portion of pass-through tubing has a fitting body that incorporates a first end, a second end and a collar, each having a longitudinal bore for receiving the pass-through tubing. The second end having an extending nose portion. A radially compressive sealing device is engagable with the first end of the fitting body. When the radially compressive sealing device is fully engaged with the first end a fluid-tight seal is formed between the device and the fitting body. A dual containment sealing device incorporates containment tubing having a flared end and a flared end fitting. The extending nose portion of the fitting body is inserted into the flared end. The flared end fitting engages the second end of the fitting body to compress the flared end to the extending nose portion to form a fluid-tight seal between the dual containment sealing device and the fitting body.

摘要： A system of elements for the formation of pipelines in units for channeling and distributing a gaseous or liquid fluid that is under pressure or under vacuum. The pipelines are created starting from an extruded section pipe with a four-sided cross section having at least one central longitudinal hole and gripping elements along the corners of its walls. A joint which can be inserted tightly into the hole of consecutive section pipes makes possible their connection with the transmission of fluid. A fixing clamp is mounted on the adjacent ends of the consecutive pipes and engages with the gripping elements to mechanically lock the pipes among one another.

摘要： A swivel coupling comprises a male member having an annular groove formed on an outer surface and a female member overlapping the male member to form a central flow passageway. An annular groove is defined at an end of the female member and the annular groove of the female member is positioned adjacent the annular groove of the male member. A locking member is movably mounted around the male and female members and an annular groove on the locking member is positioned adjacent the annular grooves of the male and female members. The grooves together define an annular ball race. A plurality of ball bearings are trapped in the ball race and the male member is rotatable relative to the female member about the ball bearings.
