  • Patent number: 10760718
    Abstract: A piping device that includes two parts, each consisting of two concentric rings joined together by a solid steel mantle that when assembled produce a confined space between the pieces of at least 50 mm and house a guide wedge and an elastomeric ring that It produces the hydraulic seal and the thickness of this solid steel mantle and the assembly area between the cavity and the guide wedge is at least twice the thickness of the pipe. The heat of the welding process between the external concentric rings is released by the device itself and the temperature inside the pipe does not exceed 120°+/?20° C., eliminating any possible internal corrosion in the areas of the welded joints, since it prevents damage to the internal lining and increases the useful life of the pipe during it operation.

  • Publication number: 20130106099
    Abstract: A fitting for use in fusion welding mating thermoplastic components includes a weld bead chamber to capture and conceal a bead formed as a result of the fusion weld. The weld bead chamber integrates the bead into the fitting so that the joined parts have a finished look without mechanical polishing or grinding of the completed piece. A stop ledge included in the weld bead chamber prevents over insertion of a pipe or other component into the fitting. A view window in the fitting permits inspection of the finished bead.

  • Patent number: 8419074
    Abstract: In a joint structure, a tube member having a polygonal cross-section can be joined to a flange surface by full penetration welding with good strength margin, without imparting unreasonable force to the weld portion. The joint structure comprises a polygonal cylindrical lower guide tube joined by butt welding to a surface of a middle flange having a through-hole of the same shape as the lower guide tube, wherein at the end of the lower guide tube, within the linear portions that constitute each of the sides of the lower guide tube, there exists a weld portion welded to the surface in at least one location and an unwelded portion located separately from the weld portion, and a level difference at least as large as a distance equivalent to the weld shrinkage of the weld portion is provided between the end positions of the weld portion of the unwelded portion.
