  • Large-gap-seal (“LGS”) assembly
    Patent number: 10436372
    Abstract: A large-gap-seal (“LGS”) assembly and methods for its assembly and use are described. The LGS assembly has an elastomer core surrounded by adjoining structural segments. Non-adjoining gap segments are located on the sidewall surfaces of the elastomer core, with each gap segment approximately centered beneath the edges of two adjoining structural segments. The gap segments are exposed by the spaces that form between the structural segments when the LGS assembly is activated. Exposing the gap segments rather than the elastomer core protects the elastomer core from damage and preserves the integrity of the seal between the isolation tool and the inner wall of the pipeline.
