Abstract: A telescoping joint is used to space out ends of a string and distribute the string weight between the tie-down locations. The joint can be compressed to reduce its length but has a locking mechanism that prevents extension under tensile loading. The seals in the joint provide a longer service life due to minimization of relative movement in the expansion joint components. The locking mechanism is preferably a ratchet system that uses a body lock ring that is enabled after breaking a shear pin.

Abstract: A lock member is provided in a housing movably between a standby position and a connected position. In a state wherein the lock member is locked in the standby position, when a pipe is inserted into an opening portion of the housing, the lock member is unlocked so as to be movable into the connected position; however, a tip portion of a detection stopper abuts against a flange portion of the pipe so as to prevent the lock member from moving into the connected position. Next, when the pipe is inserted further, and the flange portion passes the position of the detection stopper, the detection stopper moves into the connected position together with the lock member.

Abstract: In a rapid coupling, a pipe nipple engages a through hole of a socket. A first annular groove provided on the pipe nipple serves to catch a locking ring provided in the socket, in order to lock the coupled condition. A sleeve is movable on the pipe nipple, the sleeve having an inner projection to be retained by the first annular groove of the pipe nipple in a pre-assembled condition. When the pipe nipple is inserted into the socket, the sleeve abuts the socket and is then moved along the pipe nipple until the inner projection is caught by a second annular groove if the coupling is properly locked. It the pipe nipple is not moved into the socket to such an extent that the locking ring is caught by the first annular groove, the second annular groove remains visible outside the sleeve to indicate the improper coupling condition.
