<p>Apparatus for aligning the confronting ends of two pipe sections (1, 2) having a joint therebetween comprising an anchor (7) to which is secured one end of a clamp chain (8). A retainer (24) carried by the anchor is attached to the chain at a zone which enables the chain to form a loop (L) encircling one pipe section adjacent the joint. Fixed to the chain at one end thereof is a support projecting transversely of the loop a distance to extend beyond the joint and bear against the other pipe section. The chain carries a plurality of similar supports which are adjustable circumferentially of the loop to provide support for the other pipe section.</p> |
