    • A transition coupling system for use with a dual containment pipe which includes an inner primary pipe and an outer secondary pipe with an interstitial space therebetween, the transition coupling comprising. The transition coupling includes an inner body configured to engage an inner surface of the primary pipe and an outer body configured to engage an outer surface of the secondary pipe. The outer body includes at least two releasably attachable portions, at least one of which is movable relative to the other in a radial direction thereof. The inner body and the outer body are configured to define a gap therebetween when coupled to the piping system such that the gap is generally sealed and in communication with the interstitial space.
    • 一种与双重密封管一起使用的过渡联接系统,其包括内部主管和在其间具有间隙空间的外部次级管,所述过渡联接器包括。 过渡联接器包括构造成接合主管的内表面的内体和被配置为接合次管的外表面的外主体。 外体包括至少两个可释放地可连接的部分,其中至少一个可在其径向方向上相对于另一个移动。 内体和外体构造成当与管道系统连接时限定它们之间的间隙,使得间隙通常被密封并与间隙空间连通。
