<p>The saddle (3) has a radial socket (2), and heating wires in mat-shape on its inner surface. A second half-shell portion forms a stop (5) clamped mechanically to the saddle. The flanges (7) are in tangential planes parallel to the axis of the pipe (1), beyond which the internal wall of the saddle extends. The stop sidewalls (8) are parallel or at a small acute angle to the saddle inner wall, which also has heating wires forming a mat, its portions parallel to the stop sidewalls being welded to the latter. The inner wall can extend tangentially at these points, the stop sidewalls being parallel or at a small acute angle to it.</p> |
