ABSTRACT:
An improved form of articulated, segmented ring structure for an axially restrained pipe joint has an articulated, segmented ring formed from articularly interconnected ring segments and a ring adjustment mechanism operable from the exterior of the pipe joint for radially contracting the ring onto the spigot end of one pipe received within the bell end of another pipe. The segmented ring structure provides improved flexiblity in joint assembly and enhanced deflection characteristics for accommodating axial misalignment of the pipes. A ring adjustment mechanism is disclosed which is particularly suitable for use in many cases, including underwater and other limited visibility applications.
