摘要： A pipe coupling includes two or more partially annular clamp housings, each of which includes two opposing clamp members and one or more tightening elements for tightening the clamp members towards each other in a direction transverse to an axial length of the annular clamp housings. An elastomeric seal assembly is located in seal housings at opposite axial ends of a cylindrical shell. Tightening the clamp members towards each other causes the elastomeric seal assembly to apply a radially-inward clamping force on a pipe or pipes clamped by the pipe coupling. Radial force grippers are spaced about a circumference of each of the annular clamp housings. Radially-inward forces of the radial force grippers create axially-directed forces on the pipe or pipes clamped by the pipe coupling.

摘要： A pipe coupling encapsulation assembly includes an elastomeric ring including two elastomeric annular pipe interface portions that extend from two opposite axial ends of an elastomeric intermediate annular portion. The elastomeric annular pipe interface portions have a smaller annular radius than an annular radius of the elastomeric intermediate annular portion. Each of the elastomeric annular pipe interface portions and the elastomeric intermediate annular portion includes edges that face each other when the elastomeric ring is placed around a pipe. A repair coupling includes a band and opposing clamp members extending outwards from ends of the band, the elastomeric ring being radially inwards of the band.

摘要： A seal includes a sealing ring constructed with a first portion folded over a second portion so as to define at least one inner annular space bounded by the first and second portions. At least one hollow portion is at least partially annular, and is formed in the sealing ring in at least one of the first portion and the second portion.

摘要： An accessory for a clamp assembly includes a grip element which has a base portion including two opposite end faces, rows of teeth that protrude from the base portion, the teeth being arranged in rows with gaps separating them, wherein each of the teeth has a shape as viewed from one of the end faces which includes a first shape portion which has straight sides each of which extends from the base portion to an end, wherein a junction of each of the straight sides with the base portion has a radius, wherein the straight sides form borders of the gaps. Each of the teeth includes another shape portion that extends inwards, away from the gaps. The ends of the straight sides of the first shape portion and the other shape portion cooperate to grip a pipe.

摘要： A pipe coupling 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 bridge secured to the band with one or more bridge securing fasteners. The bridge spans a gap between the opposing clamp members. Anti-shearing structure is coupled to the bridge and the band, configured to prevent shearing or deformation of the bridge securing fasteners.
