A fitting for encasing an extended length of pipe comprising a plurality of segments jointed end-to-end to axially extend over the length of pipe, each of the segments being formed by a pair of mating semi-cylindrical sections, the pairs of mating sections having arcuate ends forming longitudinally extending opposed faces mating at a diametral plane, the longitudinal opposed faces being sealed together, the adjacent axial ends of the segments being circumferentially sealed together, ends of the fitting having internal seals arranged to contact and seal onto the exterior of the pipe whereby the space between said internal seals within said fitting is closed.

Modular split sleeve

A pipe fitting comprising three annular coaxial sections including a grip section, middle section, and a seal section, the grip section and seal section being separately fixed to the middle section, an annular array of grips in the grip section, an annular semi-rigid seal in the seal section, a hydraulic grip actuator in the housing for radially constricting the grips into gripping engagement with an exterior of a pipe extending into the housing, and a hydraulic seal actuator hydraulically and mechanically independent of the grip actuator, for forcing the seal radially into engagement with an exterior of the pipe, a first mechanical lock for maintaining the grips in contact with the pipe and a second mechanical lock maintaining the seal in contact with the pipe.
