Abstract:
A pipe coupling (1) includes a pipe-shaped sleeve (2) being provided with a protruding flange (4) at least in one end, said flange having a tapering end face (6). The pipe coupling further including an annular gripping ring (13) divided into ring segments (17), an annular resilient sealing ring (12) provided between the flange (4) and the gripping ring (13), a pressure ring (8) and tightening means of the bolt/nut type (26, 27). The pressure ring (8) is divided into a number of separate, mutually interspaced ring segments (10) each provided with an abutment face (9) adapted to displaceably abut the end face (6) of the flange (4). The bolts (26) extend through elongated, radially extending openings (30) in the flange (4) and through clearance holes (32) in the pressure ring segments (10).
