  • Patent number: 10378683
    Abstract: A joint structure for steel pipes according to the invention includes a pair of steel pipes having male threads formed at end portions thereof, and a coupling having a pair of sets of female threads formed therein so that the male threads of the pair of steel pipes screw in the pair of the sets of female threads, respectively. Distal end surfaces at the end portions of the steel pipes have inner circumferential edges each protruding in a direction of a pipe axis with respect to outer circumferential edges thereof. When the pair of steel pipes are coupled to each other by the coupling and the inner circumferential edges of the distal end surfaces of the pair of steel pipes are brought into contact with each other, a gap is formed between the outer circumferential edges of the distal end surfaces of the pair of steel pipes.

  • Patent number: 10161117
    Abstract: Provided is a coupling structure for easy installation and separation of a faucet. The coupling structure includes a connection body which is connected to a water supply pipe at one side and has a coupler at an opposite side. A connection pipe formed in the faucet is fitted to the coupler such that the faucet is coupled to the connection body to allow the faucet to be supplied with water and to discharge the water. A grab ring is formed in the coupler, and an actuation ring is installed in the connection pipe so as to be moved forward and backward. When the actuation ring is moved forward, the actuation ring expands the grab ring to allow the connection pipe to be separated from the coupler. Easy installation of the faucet enhances convenience in construction. Easy separation of the faucet, when necessary, enhances convenience in maintenance.

  • Patent number: 8584666
    Abstract: A solar receiver assembly includes a tube adapted to carry a heat transfer medium and a glass envelope surrounding the tube and having opposed ends. An interface is disposed between each end and the tube so as to seal and support the tube from the envelope. And the receiver includes a prism disposed over the interface to divert incident radiation away from the interface and toward the tube and/or the glass envelope. The prisms may be provided with reflective and/or anti-reflective coatings to further optimize diversion of radiation from the interface.

  • Publication number: 20130264817
    Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition.

  • Publication number: 20130257036
    Abstract: A tube coupling to receive and hold a tube includes a coupling body (10) having a throughway to receive a portion of a tube. A collet (17) in the coupling body has legs (21) with outer surfaces that engage with a tapered surface (24) in the coupling body which urges the legs inwardly to resist withdrawal of the tube. A biasing member (26) provides a biasing force without the tube inserted to urge the legs axially onto the tapered surface. The collet (17) can grip a large variety of pipe diameters. The coupling may be supplied with a number of inserts (30A-D) for sealing with the inner diameter of a pipe, the inserts having different diameters. A tool (50) for preparing the end of a pipe to receive the coupling is also contemplated.

    Abstract: A metal utility pole including a hollow, centrifugally cast, ductile iron utility pole member having a tapered exterior and variable wall thickness for providing a shortened press-fit, slip joint between interconnected pole members. The shortened joint length requires less metal than conventional press-fit, slip joints while maintaining or improving the overall strength of the joint. This is accomplished by increasing the wall thickness of one or both interconnected pole members along the joint relative to the wall thickness of the body or mid-section of the pole members.
