ABSTRACT:
Composite tubing connector assemblies (10, 10a) comprising elongated tubes (14, 14a) of composite material, with liners (12, 12a) and with the tube having upsets (16, 16a) formed by compression rings (20, 20a) located near each end of the composite tubes and end fittings such as a connector pin (22) and connector box (24) positioned over the upsets (16, 16a) and locked in place by split nuts (26, 26a), pressing the upsets (16, 16a) against the compression rings (20, 20a) within the end fittings. When coupled together in end-to-end relationshiop, a seal ring (26) is placed between the assemblies (10, 10a) to form a liner-to-liner seal. This arrangement allows the composite tube (14) to be formed and the end fittings (22, 24) coupled thereto at a later date, if desired.
