    摘要： An electrically insulated pipe joint comprises first and second metal tubular parts each having a flange at one end. The first and second tubular parts are coupled by a metal coupling sleeve surrounding the flanges and narrowing behind the flanges. A metal ring is located between both flanges, the outer diameter of which is greater than that of both flanges and which has its inner periphery in contact with the coupling sleeve. At both sides of the metal ring an electrically insulating seal ring is disposed. Further, an electrical insulation is disposed between the coupling sleeve and the first and second tubular parts.

    摘要： The invention is directed to a connector for pipe joints in which inner and outer tubular connecting members are telescopically engaged. The connecting members are secured to one another by a jointing compound which is cast in the tubular passage between the members. A preformed element, normally in the form of an O-ring is fitted at the inner end of the tubular passage to provide means for locating the members relative to each other prior to delivery of the jointing compound. A similar preformed element may be located at the outer end of the tubular passage after delivery of the jointing compound to further stabilize the joint. The jointing compound and the preformed element or elements are each electrically insulating whereby one member is electrically isolated from the other in the connector. The remote ends of the connector would normally be fitted by some other means to spaced ends of pipes to be joined but such ends may themselves constitute the connecting members where a joint is required directly between such pipes. The invention has particular utility in the connection of gas pipelines.

    摘要翻译： 本发明涉及一种用于管接头的连接器，其中内部和外部管状连接构件可伸缩地接合。 连接构件通过在构件之间的管状通道中铸造的接合化合物彼此固定。 通常为O形圈形式的预成形件通常安装在管状通道的内端，以提供用于在输送接合化合物之前相对于彼此定位构件的装置。 类似的预成型元件可以在输送接合化合物之后位于管状通道的外端，以进一步稳定接头。 接合组合物和预成型元件各自电绝缘，由此一个构件在连接器中与另一个构件电隔离。 连接器的远端通常通过一些其他装置安装到要连接的管的间隔端，但是这些端部本身可以构成连接构件，在这些连接构件之间需要直接在这些管之间的接头。 本发明在气体管道连接方面具有特殊的用途。

    摘要： A method for connecting pipe sections having a corrosionresistant lining in which a pair of sockets are connected at small diameter ends substantially equal to the outer diameter of the pipe sections to the latter, spaced from facing ends of the pipe sections with the remainder thereof, a larger diameter portion of each socket, projecting beyond the end of the respective pipe section, in which a sleeve of a material resistant to heat and to the corrosive influence of the liquid to be conveyed is placed between adjacent ends of two pipe sections, and in which the other ends of the sockets are connected to each other by at least one weld seam which is thus radially spaced from the pipe sections and the lining thereon so that the lining is not damaged by heat during forming of the weld seam. After forming of the weld seam the space between the sockets and the pipe portions enclosed thereby is filled with a molten hardenable compound having a melting point lower than that of the pipe lining, and which, however, can not damage said lining.

    摘要： A seal for attenuating energy from an electrical discharge across an interface may include a cover defining an inner volume containing a filled sealant including a semi-rigid sealant mixed with a filler having a multiplicity of discrete particles of different composition than the semi-rigid sealant such that the filled sealant is adjacent the interface when the cover is placed over said interface. A method for sealing an interface may include forming a cover defining an inner volume shaped to enclose the interface, forming a filled sealant including a semi-rigid sealant mixed with a filler having a multiplicity of discrete particles of different composition than said semi-rigid sealant, placing the filled sealant within said inner volume and placing the cover containing the filled sealant over the interface such that the filled sealant is adjacent the interface.
