    • A sealing system for forming an environmentally sealed joint with an elongate member includes a tubular substrate, a pre-expanded cover unit, and a flowable sealant. The tubular substrate includes an integral guide feature and defines a substrate bore to receive a portion of the elongate member. The pre-expanded cover unit includes a holdout and a tubular cover sleeve. The holdout includes a helically wound strip forming a tubular holdout body and a rip cord. The holdout body defines a holdout passage extending axially therethrough. The tubular cover sleeve is mounted on the holdout body. The holdout maintains the cover sleeve in a radially elastically expanded state. With the elongate member positioned with a portion thereof extending from the tubular substrate and a layer of the sealant mounted on an outer surface of the tubular substrate and/or on an outer surface of the elongate member, the pre-expandable unit can be mounted around the layer of sealant and the holdout can then be removed from the cover sleeve by withdrawing the rip cord through the holdout passage between the layer of the sealant and the holdout body to remove the holdout body and thereby permit the cover sleeve to radially contract about the tubular substrate and the elongate member, and the guide feature serves to prevent or inhibit the rip cord from contacting the layer of the sealant as the rip cord is withdrawn through the holdout passage.
    • 用于形成具有细长构件的环境密封接头的密封系统包括管状基底,预扩张盖单元和可流动密封剂。 管状衬底包括整体引导部件并且限定衬底孔以容纳细长构件的一部分。 预扩展盖单元包括固定件和管状盖套筒。 保持件包括形成管状保持体和撕裂绳的螺旋缠绕带。 保持体限定了一个轴向延伸通过其延伸的通道。 管状盖套安装在保持体上。 保持件将盖套保持在径向弹性膨胀状态。 当细长构件定位成其一部分从管状基底延伸并且密封剂层安装在管状基底的外表面上和/或在细长构件的外表面上时,预扩张单元可围绕 然后可以通过将撕开的绳索通过密封剂层和保持体之间的保持通道抽出撕裂绳,从而将密封剂层和保持层从盖套筒中取出,以移除保持体,从而允许盖套筒围绕 管状基底和细长构件,并且引导特征用于防止或阻止撕裂绳与撕裂绳通过保持通道排出而与密封剂层接触。
