<p>A coating using low-pressure injection technique is made, on half-shells that will make up the inside of the duct, and that are assembled using flanges. The said half-shells (1,2) are moulded using a noble material to ensure an effective performance in enduring the heat or effect of chemical agents and a high mechanical strength at the bindings, and being of little thickness diminishing the final weight of the part. <IMAGE></p> |
