Title (EN) AXIAL COMPENSATORS FOR PIPE LINES
(FR) COMPENSATEURS AXIAUX POUR PIPELINES
Abstract: front page image
(EN)An expansion element for insulating an axial compensator (10) comprises a pair of skid pipes (1, 2) attached in spaced relationship (11, 12) around pipe ends (13, 14) of the compensator. Each skid pipe (1, 2) is slidable in an end of a guide pipe (5) which over a substantial part of its length is surrounded by a protective pipe (8). All the spaces (9, 11, 12) between the skid pipes (1, 2) and pipe ends (13, 14) and between the protective pipe (8) and the guide pipe (5) are filled with heat insulation material. Due to the ability of the skid pipes (1, 2) to slide in the guide pipe (5), the expansion element follows changes in length of the compensator (10) in response to temperature variations. The expansion element is fitted to the axial compensator (10) before the two are mounted in a pipe line.
(FR)Un element de dilatation pour l"isolation d"un compensateur axial (10) comprend une paire de tuyaux coulissants (1, 2) attaches de maniere espacee (11, 12) autour des extremites (13, 14) du compensateur. Chaque tuyau coulissant (1, 2) peut coulisser dans une extremite d"un tuyau de guidage (5) qui est entoure sur une bonne partie de sa longueur d"un tuyau de protection (8). Tous les espaces (9, 11, 12) entre les tuyaux coulissants (1, 2) et les extremites de tuyaux (13, 14) et entre le tuyau de protection (8) et le tuyau de guidage (5) sont remplis d"un materiau d"isolation thermique. Grace a la capacite des tuyaux (1, 2) de coulisser dans le tuyau de guidage (5), l"element de dilatation suit les changements de longueur du compensateur (10) en reponse aux variations de temperature. L"element de dilatation s"adapte sur le compensateur axial (10) avant que ces deux organes ne soient montes tous dans un pipeline.
