Abstract
A chuck assembly (8) is described comprising a plurality of external jaws (103) arranged in an annular configuration; and a corresponding plurality of internal jaws (122) positioned within a pipe (13) in use with the internal and external jaws in alignment. The jaws (103,122) are radially movable towards each other to grip the pipe wall therebetween. Each jaw (103,122) includes a gripping portion comprising a recess (128) or projection (127) respectively which cooperate to assist the gripping of the pipe wall by the chuck assembly (8). Examples of the use of these chuck assemblies in friction welding apparatus and pipeline construction apparatus are described.
