A split T-shaped pipe serving as a housing device and comprising: an annular case body that has a split part in at least one location in the circumferential direction, and that surrounds the outer circumferential surface of a water pipe in a sealed state with a seal material therebetween; and fasteners for tightening the split part, thereby joining a plurality of split pieces constituting the case body. Joining surfaces are provided at the circumferential end portions of the split pieces, and protrusions protruding along the circumferential direction are formed on the joining surfaces but only at both end portions of the case body in the pipe axis direction of the water pipe.

A pipe coupling capsulation assembly includes a band having an inner annular seal element wrappable around a pipe, opposing clamp members that extend from the band, at least one tightening element for clamping together the clamp members, and a plurality of retaining elements extending from the band. Each retaining element overlies a portion of an adjacent one of the retaining elements.

The present model refers to a bolted and welded clamp-type repair with bolts and nuts housed in recessed locations that will be hermetically insulated by welding plugging discs to be used in the repair and maintenance of pipes. The clamp-type repair comprises a lower part (1) and an upper part (2) that will perfectly accommodate the pipe, wherein said lower part (1) and upper part (2) each comprise a flanged portion (3) at both ends, and the flanged portions (3) each comprise at least one recess (4) to accommodate the bolt-nut assembly (7) where the plugging discs (8) will be positioned immediately above. The welding process of the edges between the same and next to the pipe (12) and the plugging discs (8) next to the surface of the flanges (3) guarantee the necessary safety and enable the repair to be defined as permanent, without the need for later replacement.

A clamp for repair of a pipe coupling, includes a clamp unit including a side wall with an inner surface, the inner surface having a curvature dimensioned to match an outer curvature of a pipe coupling to be repaired. A coupling on the clamp unit is constructed and arranged to couple a first portion of the clamp unit with a second portion of the clamp unit. The coupling, when secured, operates to induce a radially inward force on the inner surface of the clamp unit. A window is formed as an opening in the side wall of the clamp unit. The window is dimensioned to expose a flange of a pipe coupling to be repaired.
