ABSTRACT:
Single or multi-piece, pipe joint seal elements have at least one slidable interface that contacts a sealing surface of an end ring attached to a cementitious pipe liner. The slidable interface allows for slippage between seal pieces and/or seal piece-end ring surfaces during pipe joint assembly and disassembly. The end rings help distribute and minimize rotational and other stresses exerted upon the liner end surfaces and seal pieces. Such end ring surfaces further provide a quality surface for the seal element to effect a seal. The slidable interface seal is especially useful for joining brittle-lined pipe sections handling harsh fluids such as geothermal brine, etc.
