    Abstract: A connection includes a first and second surface stationary with respect to one another and a primary seal and secondary seal are formed between the surfaces and a labyrinth redundant seal is formed between the first and second surfaces and intermediate the primary and secondary seals. A connection for sealing against pressure may also include a retainer disposed within a housing receptacle a conduit disposed within a bore of the retainer. A primary seal may be formed between the conduit and the receptacle and a secondary seal may be formed between the retainer and the receptacle. A labyrinth seal may be formed between the retainer and the receptacle and intermediate the primary and secondary seals.

    Abstract: An environmentally safe underground piping system which employes a inner flexible fluid supply piping system contained within an outer non-flexible containment piping system which interconnects a series of surface access chambers. Both the flexible supply and and non-flexible containment piping systems are interconnected by a series of directional fittings and couplings. The containment system may be installed, integrity tested, inspected and backfilled, prior to installation of the supply piping system which allows for a faster and more economical installation.

    Abstract: A pipe coupling is disclosed which is capable of being periodically coupled and uncoupled between two lengths of pipe. The pipe coupling includes a first and a second union which are fixed between an intervening length of pipe such that the intervening length of pipe does not have to be of a precision length. The outer periphery of one end of the pipe contains serrations and this end is fixed to the first union by a serrated compression ring and a backnut. By tightening the backnut onto the first union, the compression ring firmly engages the serrations on the pipe and prevents axial movement thereof. The second union includes a non-binding compression ring and a backnut as well as having an internal elongated bore of approximately the same diameter as the outer diameter of the pipe. As the backnut is tightened onto the second union, the compression ring is squeezed about the outer periphery of the pipe and forms a seal therewith. One benefit of this second union is that it can be repeatedly coupled and uncoupled relative to the pipe to permit the intervening length of pipe to be moved into or out of the second union as the need arises. The second union also permits a tight seal to be formed even when a limited amount of misalignment exist between the pipe and the second union.

    Abstract translation: 公开了一种能够在两段管道之间周期性地联接和分离的管接头。 管接头包括第一和第二接头，其固定在中间长度的管之间，使得管的中间长度不必具有精度长度。 管的一端的外周边包含锯齿状，该端部通过锯齿状的压缩环和盘簧固定在第一接头上。 通过将螺母拧紧到第一接头上，压缩环牢固地接合管道上的锯齿并防止其轴向移动。 第二联合体包括无约束力的压缩环和底盘以及具有与管的外径大致相同直径的内部细长孔。 随着将螺母紧固到第二接头上，压缩环围绕管的外周被挤压并与其形成密封。 该第二联合体的一个好处是可以相对于管道重复地联接和分离，以允许管道的中间长度根据需要移入或移出第二联合。 即使在管道和第二联管之间存在有限量的不对准的情况下，第二联管也允许形成紧密的密封。
