Abstract
A fitting is attached to a composite pipe by inserting a tubular root portion of the fitting into an end of the pipe and then tensioning longitudinally-extending tensile elements distributed around the fitting. This moves an outer wedge component of the fitting longitudinally relative to the pipe to force an opposed inner wedge formation radially inwardly toward the roof portion, clamping the fitting to the pipe. The fitting may be an end fitting to enable the pipe to be joined to another pipe or conduit, or may be an in-line fitting used to join two lengths of pipe end-to-end.
