| A mechanical coupling for joining pipe elements has a seal. The seal has sealing surfaces with one or more projections that form closable leak paths between the coupling and pipe elements being joined. The leak paths close when the coupling is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings can be discovered during pressure testing and before service pressure is applied. | ||||||

| An annular gasket intended to provide a tight assembly between a first and second pipe after crimping, including an axis of revolution, whereof a section parallel to said axis is a curve formed by a series of an odd number of circle segments Ci connected by apices Si forming a regular polygon, i varying from 1 to 2*n+1, n being a positive integer greater than or equal to 1, the apex Si being the center of the circle passing through the apices Si+n and Si+n+i modulo 2*n+1. Such a curve is said to have a constant width. The apices Si advantageously form a polygon. | ||||||
| 12 | Crimp evident seal | US12512320 | 2009-07-30 | US09188260B2 | 2015-11-17 | Scott Lee Spence |
| An O-ring has a flange which includes a plurality of slots, such that, when inserted into an annular groove of a pipe fitting before crimping, the slots allow the flow of fluid therethrough, such that an installation would not pass pressure tests until such time as a proper crimp has been made. Such a design allows the use of conventional push-on pipe connections by utilizing a unique O-ring seal which works in conjunction with standard push-on crimp-type pipe fittings and conventional crimping tools for subsequently sealing the connection. The O-ring is either circular or elliptical in cross section and the slots define equally spaced annular segments. | ||||||

| A pressure-relieving safety assembly, comprising a sleeve and collar, protects against human injury and loss of life by blocking flow of fluid from a ruptured high pressure conduit and provides pressure relief for escaping fluid. This pressure-relieving assembly includes a sleeve that encircles the high-pressure line and is secured to, at one or both ends of the line, a coupling. The sleeve is secured to the coupling(s) by a collar having raised portions that provides a path for fluid that has escaped from the conduit at a burst or pin-hole failure location, to flow towards the ends of the conduit, indicating to the user that a conduit failure has occurred. The sleeve lowers the fluid velocity while the path provided by the collar prevents the fluid pressure from building up behind the sleeve. | ||||||

| A socket part actuated without pressure for a fluid coupling is provided with means, which mechanically seal, to a large extent, the insertion space of a plug against the penetration of foreign matter. In addition, a throttling device is provided, which practically does not obstruct the fluid connection for an inserted plug, while a high flow resistance is produced for a plug that has been pulled out, without, however, completely blocking the flow path. The associated plug also has a sealing device in order to protect the flow channel against the penetration of particles when the plug is removed. In case the plug is connected to a compressed-air tank, this is provided with a throttling device, which practically does not obstruct flow for an inserted plug, but forms considerable flow resistance for a removed plug without completely blocking the flow. | ||||||

| The invention relates to a fitting for connecting lengths of pipe or tube by compression, having a substantially cylindrical internal contour. The fitting has at least one ridge which is configured in a radially outward direction and in which a sealing element is provided. The fitting is slidable onto the lengths of pipe or tube, the internal contour of the fitting having a region of non-circular cross-section at least one end. The invention also relates to a connecting arrangement for connecting lengths of pipe or tube by compression, comprising at least one length of pipe or tube and a fitting plus a sealing element which is arranged between the two latter in a ridge in the fitting. The internal contour of the fitting is partly of a non-round form and at least one axial gap which extends over the entire connecting region is formed between the length of pipe or tube and the internal contour of the fitting in the uncompressed state. | ||||||

| A connecting piece for establishing a connecting arrangement for a pipe which can be pressed together comprises a stub which can be inserted into a pipe. Profilings for the pressing-together with the pipe and a stop are on the stub. At least one radially projecting spacer is provided on the stub.

| 19 | Service line interior by-pass fitting | US181671 | 1980-08-27 | US4434816A | 1984-03-06 | Bernard A. Di Giovanni; Francisco J. Ciminiello |
| Interior by-pass for underground gas service line is installed from building basement without need for excavation, and has a tightenable adapter attached on each end of the by-pass tubing to connect and seal the tubing to the interior periphery of the service line. Each adapter provides a pair of spaced-apart expanded sealing gaskets between the tubing and the service line, and a gas-leakage passage extending from the interior of the tubular adapter to the exterior spacing between the adapter gasket pair. Temporary gas-tight plugs are provided at respective locations between each leakage passage and the adjacent end of the by-pass tubing, and compressed natural gas test-pressure is applied within the tubing. Via both of the referred to leakage passages, the test pressure is exerted against all of the gasket seals to confirm gas-tightness thereof. Techniques are described for installing each adapter and the by-pass tubing, working only from the service end of the line, including installation of the servce end adapter prior to the blind end adapter; the use of temporary gas-inflation bags to permit installation of the by-pass in the face of service gas flow; and structure on each adapter to fully expand the innermost gasket of each pair before the outermost gasket is expanded. | ||||||
