COMPOSITE TO METAL END FITTING JOINT

摘要

A composite torque pipe to metal fitting joint including concentric inner and outer shells formed with respective smooth conical surfaces projecting distally and respectively tapered radially inwardly and radially outwardly to form an annulus expanding in thickness for receipt of a tapered connector ring complementally shaped at one end of a composite pipe and bonded along the interface. The present invention includes selecting the sleeves with the corresponding shells and, forming the torque pipe with the tapered ring and bonding the tapered ring in the annulus.

1. A composite pipe to metal end fitting joint device comprising:
a metal inner sleeve configured on one end with an annular flange and projecting distally therefrom to be formed with an annular inner shell configured with an exterior, distally extending, continuous inwardly tapering conical inner sleeve surface; a metal outer sleeve received over the inner sleeve abutted on one end with the annular flange and further configured with a distally projecting outer shell concentric with the inner shell and formed with an interior, distally and radially outwardly expanding continuous outer shell surface cooperating with the inner sleeve surface to form an annulus distally expanding in thickness: a composite pipe configured on one extremity with a connector ring formed with inner and outer surfaces; and a bond on the interface between the connector ring and shell surface and between the connector ring and the sleeve surface.
