摘要： One or more rigid sealing segments are attached to pipe end sections and the assembly lined to form a fluid-resistant joint. A segment surface forms the primary sealing interface of lined pipe sections without the need for a conventional removable liner edge seal. The lining process and configuration sealably bonds the liner to the fluid-resistant sealing segment and to the non-fluid-resistant pipe. The manner of bonding both avoids (or limits) liner stress and covers the non-fluid-resistant material of the pipe. In an alternative embodiment, the sealing segments are engaged at mating threaded surfaces, the mated threads providing a single primary sealing and engagement interface. Redundant liner end sealing may also be accomplished by a sandwiched deformable material if added reliability of sealing harsh fluids is desired. In another embodiment, portions of the rigid sealing segments are slidably mounted relative to each other and the primary seal interface is temperature actuated.
