Abstract
Méthodes de fabrication dun compensateur dexpansion comprenant ceci : extruder une doublure en plastique interne avant des première et deuxième extrémités espacées, une surface interne, une surface externe et un volume intérieur allant de la première extrémité à la deuxième extrémité; positionner la doublure de plastique interne à lintérieur dun conduit de métal allongé tandis que la doublure de plastique interne se trouve à une température élevée, le conduit de métal allongé présentant des première et deuxième extrémités espacées, une surface interne, une surface externe et une section dexpansion et de contraction; sceller les extrémités ouvertes de la doublure de plastique interne; introduire un fluide sous pression dans le volume intérieur de la doublure de plastique interne pour faire prendre de lexpansion à la doublure de plastique interne tandis que la doublure de plastique interne expansée présente une section dexpansion et de contraction; et refroidir la doublure de plastique interne.
