DEVICE FOR COUPLING PIPE SECTIONS

摘要

A device for coupling two pipe sections comprises a clamping band (1) of U-shaped cross section with two inwardly directed flanges for encompassing end beads of the pipe sections which are to be coupled. The ends of the clamping band (1) have cylindrical pockets (2) each accommodating a cylindrical element (4, 5) which is rotatable about its own axis in the pocket. The clamping band is clamped by means of a threaded screw (6) which is passed through an unthreaded hole (5a) in one cylindrical element and unthreaded holes (3) in the ends of the clamping band, whereupon the screw finally is in threaded engagement with the other cylindrical element (4).
