METHODS AND DEVICES FOR JOINING PIPES, AND FOR ATTACHING THE PIPES TO CONNECTING PIECES ON T-PIPES, BENDS AND EQUIPMENT SUCH AS VALVES, FAUCHETS, MEASURING INSTRUMENTS, ETC.

摘要

Mechanical constriction of pliable pipes (1), for example, annealed copper pipes or pipes of plastic, a corrugated fitting sleeve or connecting piece (3) on, for example, a T-pipe, bend or equipment such as, for example, valves, takes place with the aid of a clamp coupling consisting of an outer sleeve (7) which is rotatable relative to an inner sleeve (4) which is provided with a longitudinal slot (9). Mechanical joining of hard pipes (9, 10), for example, of copper or steel, or attaching of such pipes to a connecting piece (10) on a T-pipe, bend or equipment such as, for example, valves, is provided for with the aid of such a clamp coupling (11.13, 16.18) where the interior of the inner sleeve is provided with at least a pair of annular beads (18) and a cylindrically shaped sealing gasket (16).
