285065000 | IDENTICAL HALVES (E.G., TRAIN LINE TYPE) | 9 |
20160076678 | Cylindrical Pressure Vessel Clamping Device - A pressure clamp for connecting pressure vessel segments can include a pair of semi-circular sections, which can be placed around the ends of the segments, so that there is a slight gap between the semi-circular sections. The inner surfaces of the semi-circular sections can be formed with two notches with beveled surfaces. The beveled surfaces can engage corresponding slanted surfaces on the segment ends, to urge the segments towards each other as the clamp is tightened. A pair of jack screws can be threaded through the semi-circular sections so that the jack screws extend slightly outwardly from one of the sections and contact the other section at the beginning of the tightening process, to establish an initial assembly gap. As fasteners tighten the clamp around the segment, the jack screws can be backed out to maintain a uniformly decreasing assembly gap between the semi-circular sections. | 03-17-2016 |

20100007136 | NOVEL LOCKING PIPE JOINT AND A METHOD OF MAKING THE SAME - The present invention provides a novel locking pipe joint for use in fluid-carrying pipe systems. The locking pipe joint of the present invention provides a system of joints that will withstand the stresses and forces imposed on a pipe system carrying fluids during filed conditions. The joint is constructed on a push-fit principle. Sealing rings are used to make the joint leak-proof. Splines are provided to sustain the longitudinal forces imposed on the joint, and longitudinal ribs are provided on the outer surface of the jointed pipes to withstand the torsional loads. The joint is simple in its construction, easy to assemble in field and cost effective. | 01-14-2010 |
20150300541 | COUPLING CONNECTION FOR CORRUGATED PIPES - A coupling connection for corrugated pipes includes a coupling element, a support ring which is attachable in a positive fit against an inner wall face of the corrugated pipe, a first annular element which is axially fixable on a circumferential face of the corrugated pipe, a portion of the corrugated pipe being enclosed between the support ring and the first annular element and being fixable axially immovably, and an annular sealing chamber, enclosed circumferentially in a transition region between the support ring and the corrugated pipe, receiving a sealing element, on which a deformation force acts in a functional position which is fixable using a fixing element, including a second annular element, which circumferentially encloses the coupling element and is circumferentially attachable and movable in translation with respect thereto, the first annular element and the second annular element being arranged mutually coaxially. | 10-22-2015 |
20150316181 | Threaded Connection - A threaded connection for use on oil field tubular. The connection has a dual tapered thread comprising a dual helical thread having a first, straight threaded portion and a second, angled portion, the threaded connection comprising a pin connection and a box connection both of which have thread-free sections. The thread-free section on the pin and the box are comprised of frustoconical surfaces and cylindrical surfaces. The thread-free section of the pin in addition to having a frustoconical surface and a cylindrical surface has an annular, radially outwardly radiused protrusion which, when the box and the pin connection are made-up is in interference engagement with the frustoconical surface in the box. | 11-05-2015 |
20160109043 | PIPE ADAPTER DEVICE - A pipe adapter may include an inner tube member, a fastener member, an outer sleeve member, a compressible sleeve member, and a fitting member. The inner tube member may have a proximal section and a distal section. The fastener member may be connected to the inner tube member along the proximal section thereof. The outer sleeve member may girdle the inner tube member and may be connected to and extend outwardly from the fastener member. The compressible sleeve member may be connected to and may extend outwardly from the outer sleeve member and may be positioned to overlie the inner tube member. The fitting member may be connected to the distal section of the inner tube member and may be in communication with the compressible sleeve member. At least a portion of the fitting member and/or the compressible sleeve member may be positionable within a portion of a pipe. | 04-21-2016 |

20150021901 | GUIDE LINER FOR BREAK-AWAY FITTING - A break-away fitting facilitates installation and removal of a pump in wet well system, along at least one guide rail. When installed, the fitting mates an outlet of the pump to an outlet pipe of to wet well. The fitting has a body with a first and a second surface, the surfaces arranged to be substantially perpendicular to each other. A flanged opening in the first surface is sized and adapted for attaching the body to the outlet flange of the pump. The second surface has indentations for engaging the at least one guide rail, so that the body slides in the vertical channel. To minimize the dangers from static electricity in the wet well, the body may be formed from a non-sparking material, such as brass or bronze, or a surface of the indentations may be covered by a non-sparking material, including high-density polyethylene or poly(tetrafluoroethylene). | 01-22-2015 |
