APPARATUS FOR ALIGNING PIPES Apparatus for aligning the confronting ends of two pipe sections having a joint therebetween comprising an anchor to which is secured one end of a clamp chain. A retainer carried by the anchor is attached to the chain at a zone which enables the chain to form a loop encircling one pipe section adjacent the joint. The loop carries a plurality of circumferentially spaced supports for supporting the other pipe section in a position to be welded to the first pipe section. The anchor and the retainer are relatively adjustable to enable the loop to be contracted and expanded. |
