The second deformable portion is positioned longitudinally between the first deformable portion and the third deformable portion and at least one of the first deformable portion and the third deformable portion is sealable to the first tubular when the first deformable portion or the third deformable portion is deformed. Further, the second deformable portion is sealable to the second tubular when the second deformable portion is deformed. | 03-05-2009 |
| 20110042905 | Fire And Chemical Resistant Gasket - An annular, chemically nonreactive shell 18 is formed with a base 42, a radially inwardly disposed surface 28 and with a pair of sidewalls 30, 32 that are raised relative to the base. A fire resistant, intermediate core 20 is formed with an annular body 36 and with a radially outwardly projecting end 34. A substantial portion 24 of the core 20 is mounted between the sidewalls 30, 32 of the shell. When installed between opposing pipe flanges 12, the radially inwardly disposed surface 28 of the shell 18 is compressed between the pipe flanges 12 adjacent to the bores of the pipes 14 and provides a fluid tight seal to prevent a process stream 16 from reaching the core. Likewise, the sidewalls 30, 32 are compressed by the pipe flanges 12 and, in turn compress the core portion 24 disposed therebetween. The outer end 34 and a radially outwardly disposed portion 26 of the core 20 expand to protect the shell 18 from heat and flame. | 02-24-2011 |
| 20150021863 | Mutiple-Leak Proof Sealiing System - A Multipe-leark proof sealing system which is used to join two components sealed together and comprises: a first adapter ring and a second adapter ring and comprising a first joint face and a second joint face, which are opposite to each other, respectively, wherein the first joint face and the second joint face have gasket grooves which are opposite to each other; sealing gaskets which are embedded into the first adapter ring's and the second adapter ring's gasket grooves; a metal sealing ring installed between sealing gaskets on the first adapter ring and the second adapter ring; an auxiliary sealing ring joining the sealing ring's radial inner wall. The sealing structure with multiple sealing surfaces is developed when the first adapter ring and the second adapter ring join together by fastenings. | 01-22-2015 |
| 20160138739 | SEAL RING STRUCTURE FOR HIGH-PRESSURE PIPE JOINT - Provided is a seal ring structure for a high-pressure pipe joint that is capable of improving the sealing performance and vibration resistance of a pipe joint. The seal ring structure comprises a seal ring and a retainer. The seal ring is donut shaped. A cross-section of the seal ring comprises a quadrangle having two diagonal lines that are orthogonal to each other. One diagonal line is parallel to a planar perpendicular line formed by the donut shape, and opposing vertexes on the diagonal lines are in contact with the end face of each joint. The retainer is able to engage with the peripheral edge of the joint end face. | 05-19-2016 |
