F16L19/00—Joints in which sealing surfaces are pressed together by means of a member, e.g. a swivel nut, screwed on, or into, one of the joint parts
F16L19/06—Joints in which sealing surfaces are pressed together by means of a member, e.g. a swivel nut, screwed on, or into, one of the joint parts in which radial clamping is obtained by wedging action on non-deformed pipe ends
F16L19/075—Joints in which sealing surfaces are pressed together by means of a member, e.g. a swivel nut, screwed on, or into, one of the joint parts in which radial clamping is obtained by wedging action on non-deformed pipe ends specially adapted for spigot-and-socket joints for pipes of the same diameter
