20110291407 | JOINT FOR TUBULAR MATERIALS - An end-to-end tubular joint includes first locking pieces cut from the first tube and second locking pieces cut from the second tube, where the cuts have radial cut faces on the axially aligned cuts. The first and second locking pieces are interlocked with lateral extensions of the respective locking pieces bearing against one another and the radial cut surfaces distributed circumferentially around the joint so as to constrain relative movement between the parts. The first locking pieces are welded to the first tube and the second locking pieces are welded to the second tube to form a tube joint. An alternative forms cutouts in the first tube and fits locking pieces into the cutouts that are welded to a second member, such as a second tube or cylinder that fits into the first tube so as to form the tube joint. | 12-01-2011 |
20130043676 | OVERMOLDED SEAL FOR BARBED TUBING CONNECTION - A barbed fitting tubing assembly utilizes a thermoplastic tube which is pressed onto a barbed thermoplastic fitting of a device, for example, such as a filter. A thermoplastic sleeve is molded over the tubing where it engages the barbed fitting as well as the end of the fitting where it connects to the device such that the overmolded sleeve engages in an over-mold groove in the fitting so that it is form-locked in position. The tubing, the barbed fitting and the overmolded thermoplastic sleeve are all made of a thermoplastic material and the overmolded thermoplastic sleeve is installed such that such that at least one of a cross-linked chemical bond or a physical mechanical interlocked connection is formed to provide a leak-proof connection. | 02-21-2013 |

20090045621 | Crimp-On Pipe Connection Accessory - A pipe connection accessory | 02-19-2009 |
20090072534 | SEALED STRUCTURE OF CIRCULAR TUBULAR HEAT PIPE - A sealed structure of a circular tubular heat pipe is formed on a distal opening of a heat pipe. A pressed recess portion recessed inwards from one side of a wall portion is formed on the distal opening. The wall portion of the distal opening is pressed from the pressed recess portion to the other side of the wall portion and is sealed therewith, thereby forming a flattened section of the heat pipe. The flattened section deflects toward one side of the body of the heat pipe, and it has two wing portions bending obliquely toward the pressed recess portion. The tip of one of the wing portions is brought into contact with the outside of the tip of the other wing portion, so that the flattened section forms a curled portion that reduces gradually from bottom to top. | 03-19-2009 |
20100007140 | CRIMP FITTING FOR CORRUGATED STAINLESS STEEL TUBING - A fitting incorporating a crimp sealing device and a method of forming a seal between a length of corrugated tubing and the fitting are provided. A sealing crimp is formed over at least one corrugation of the tubing, where the sealing crimp can utilize a preformed bend or bulge to form a crimp and seal. Alternatively, the sealing crimp can apply pressure radially against an outer sleeve of the fitting, such that at least one corrugation of the tubing is compressed axially or radially to form a primary seal. The outer sleeve also can include one or more gaskets arranged between the outer sleeve and the tubing for forming a secondary seal. An inner sleeve can be received radially inside the outer sleeve, and one or more gaskets can be arranged between the inner sleeve and the tubing. Further, a jacket crimp can be applied against an end of the sleeve member to contact a jacket that at least partially covers the tubing. | 01-14-2010 |
20100225107 | Gas Tight Tubular Joint or Connection - Gas tight tubular joint or connection, particularly related to mono diameter tubular body in the form of a pipe or casing being used in connection with the production of oil and/or gas, where the pipes or casings are manufactured from tubular sections and where the tubular sections, after being interconnected at their respective ends, are finally formed by expansion. The pipes or casings are formed from at least two, one outer and one inner tubular section. The ends of each of said respective section is overlapping the next, succeeding tubular section, whereby one or more of the inner, intermediate or outer tubular sections are of different metallic materials and/or different thickness, and under the deformation process, is plastified or plastically deformed in the overlapping zone forming a metallic seal and thereby providing gas pressure integrity between the inside and outside of the expanded tubular pipe/casing. | 09-09-2010 |
20160076685 | END CONNECTOR FOR HIGH PRESSURE REINFORCED RUBBER HOSE - An swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20,000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the device will fail before the connector pops off the hose. The connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006. | 03-17-2016 |
