BELL AND SPIGOT JOINT WITH WEDGE LOCK

摘要

In a spigot and socket pipe joint, radially inward flanges, each reducing in width from one end to the other, are formed on the outer end of the socket so as to provide a circumferential space of varying width between the flange and the spigot. A circumferential wedge channelled to receive the flange is inserted in the wide flange-to-spigot space and is then displaced circumferentially to wedge the flange and spigot together.
