<p>A pipe repair clamp 10 especially for subsea offshore work has two half-shells 12, 14 held together around the pipe 16 by two sets of diametrically opposite interlocking formations 150, 152 comprising in each set a series of abutments 154, 156 integral with a half-shell and a series of hooks 158, 160 integral with the other half-shell. The abutments are arranged in a castellated formation and provide first surfaces opposed to and engaged by second surfaces provided by the hooks. The half-shells 12, 14 have opposed abutting longitudinal faces with a longitudinal seal between each two abutting longitudinal faces extending along the half-shells. The longitudinal seals at their ends seal against 180 DEG seals at each end of the clamp, each 180 DEG seal being at an end of a respective half-shell 12, 14. An annular gap 18 between the clamp 10 and the pipe 16 is fillable with repair grout. <IMAGE></p> |
