Abstract

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.

Abstract

A metal to composite tube joint including an elongated interior fitting constructed with an exterior barrel, reduced in exterior diameter to form a distally facing annular shoulder and then projecting still further distally to form an interior sleeve having a radially outwardly facing bonding surface. An elongated metal outer sleeve formed proximally with a collar constructed for receipt over the barrel and increased in interior diameter and projecting distally to form an exterior sleeve having a radially inwardly facing bonding surface cooperating with the first bonding surface to form an annulus receiving an extremity of a composite tube and a bond bonding the extremity of the tube to the bonding surfaces.
