Abstract

L'isolant selon l'invention, qui revêt le tube 1, se compose d'une couche en un mélange de polymères 3, de 0,8 à 2 mm d'épaisseur, prévue entre une couche de protection contre la corrosion en polyéthylène 2, de 0,5 à 1mm d'épaisseur, appliquée à la face externe du tube, et une couche en polyéthylène 4, de 0,3 à 1 mm d'épaisseur, servant à limiter les efforts de poussée exercés sur le tube.
