<p>In improved connections for tubular equipment made of composite materials, each connection (1, 2) has, for each end of the tube, a fitted, glued inner sleeve (4), a hot shrink-fitted, glued outer sleeve (5), and means for connecting the two outer sleeves. This type of connection makes it possible to use tubular equipment made of composite materials in oil wells under the harshest corrosion conditions.</p> |
