<p>The pipes (2, 4) formed by metal pipes (1, 3), which are provided with an anticorrosion layer (6) of a fairly large thickness, need for the junction area, an independent insulating lining (7), since this area may not be coated with the anticorrosion layer (6). The insulating lining (7) is comprised of a sleeve (8) which is fixed onto the anticorrosion layer (6) of the section (1) as well as a collar (9) to which is connected preferably a sleeve (10) bearing onto the anticorrosion layer (6) of the joint (3). The collar (9) may have the form of a bellows. It is possible to have a ring-shaped collar which may be stuck against the front surface of the joint (3). </p> |
