    • A method of manufacturing an annular seal (500), the method comprising the steps of: (i) providing an intermediate (10) having an annular layer of an elastomeric first material (100) bonded to an annular layer of a second material (200), the second material being different from the first material; and (ii) machining the intermediate to form the annular seal comprising the first and second materials, wherein: • the intermediate (10) is machined to provide a profile that is generally U-shaped and is defined by a radially extending wall (1), an outer flange wall (2) extending axially from the radial wall (1), and an inner flange wall (3) facing the outer flange wall (2) and extending axially from the radial wall (1); and • the annular seal (500) has a seal lip (4) that extends radially inward from the inner flange wall (3), whereby the seal lip (4) is formed from the second material (200) and the second material has one or more of: a lower coefficient of friction, a higher heat resistance, a higher wear resistance and/or a higher chemical resistance than the first material (100).
    • 一种制造环形密封件(500)的方法,所述方法包括以下步骤:(i)提供具有结合到第二材料(200)的环形层的弹性体第一材料(100)的环形层的中间体(10) ),所述第二材料与所述第一材料不同; 并且(ii)加工所述中间件以形成包括所述第一和第二材料的所述环形密封件,其中:•所述中间件(10)被机加工以提供通常为U形且由径向延伸的壁(1)限定的轮廓, ,从所述径向壁(1)轴向延伸的外凸缘壁(2)和面向所述外凸缘壁(2)并从所述径向壁(1)轴向延伸的内凸缘壁(3); 和环形密封件(500)具有从内部凸缘壁(3)径向向内延伸的密封唇缘(4),由此密封唇缘(4)由第二材料(200)形成,并且第二材料具有一个 或更多的摩擦系数,更高的耐热性,更高的耐磨性和/或比第一材料(100)更高的耐化学性。

    • A non-conductive multi-layered ringed sealing gasket for mating pipe joints along a piping assembly comprising at least two mutually joined ring-shaped bodies each having a top surface portion, a top gasket section bonded with, adhered to, or part of the top surface portion, a bottom surface portion, and a bottom gasket section bonded with, adhered to, or part of the bottom surface portion. The bottom surface portion of one of the bodies is mated to a top surface portion of another of the bodies forming multi-layers. The at least two mutually joined ringed-shaped bodies in combination comprise a sealing ring so that the top and bottom gasket sections are dimensioned with a total thickness no greater than the diameter of the piping assembly in each pipe-joint half mated by the gasket. The ringed sealing gasket can be comprised of a metal and the bottom gasket section is separated from the top gasket section by an inner portion that is comprised of one or more non-conductive materials that are ductile but do not flow during dynamic motion and forces associated with the motion of the pipe joints wherein at least one layer of the inner portion includes rings with toroidal wrapped fibers having voids filled with adhesives such that shear forces occurring during movement of the piping assembly are distributed predominantly in the tensile direction along the axial length of the fibers, thereby eliminating cracking of the gasket under excessive loads.
    • 一种不导电多层环形密封垫圈,用于沿着管道组件配合管接头,包括至少两个相互连接的环形体,每个具有顶表面部分,顶部垫圈部分粘合,粘附或顶部的一部分 表面部分,底面部分和底部衬垫部分,其结合,粘附或部分底部。 其中一个主体的底表面部分与另一个形成多层的主体的顶表面部分配合。 组合的至少两个相互连接的环形体包括密封环,使得顶部和底部垫圈部分的尺寸设计为总厚度不大于由垫圈配合的每个管接头半部中管道组件的直径。 环形密封垫圈可以由金属组成,并且底部垫圈部分由顶部垫圈部分与内部部分分离,该内部部分包括一种或多种非导电性材料,其在动态运动期间是延性的但不流动, 管接头的运动,其中内部部分的至少一层包括具有填充有粘合剂的空隙的环形缠绕纤维的环,使得在管道组件的运动期间发生的剪切力主要沿着轴向长度的拉伸方向分布 纤维,从而消除了在过载下的垫片的破裂。
