A fluid piping system (10) comprising a plurality of two or more coupled first (12) and second (12) pipe spools, wherein: said first and second pipe spools comprises: a downstream end (16) and an upstream end (18); an inner pipe (24); an outer pipe (26) defining an insulating area (28) is under vacuum when said first spool and said second spool is coupled or uncoupled; and at least one inert gas line (30) disposed between said inner pipe (24) and said outer pipe (26) and running through said insulating area (28); said first pipe spool (12) is coupled to said second pipe spool (12) such that an annular space (32) is formed between said first pipe spool and said second pipe spool; and said annular space (32) is disposed such that inert gas may be supplied to said annular space (32) through at least one of first pipe spool inert gas line (30) or said second pipe spool inert gas line (30). The system further comprises a valve (36) disposed at said upstream end (18) of said first pipe spool (12) such that communication may be established between said insulating area (28) and said annular space (32), and a remote temperature measurement system (49). La présente invention concerne un système de tuyauterie pour fluides (10). Ce système est constitué d'une pluralité de premiers (12) et seconds (12) enrouleurs de tuyaux couplés. Ces deux types d'enrouleurs comportent notamment, une extrémité aval (16) et une extrémité amont (18), un tuyau intérieur (24), un tuyau extérieur (26), et au moins une ligne à gaz inerte (30). Le tuyau extérieur (26), qui définit une zone d'isolement (28), est sous vide pour le couplage ou le découplage entre les deux types d'enrouleurs. La ligne à gaz inerte (30), qui est établie entre le tuyau intérieur (24) et le tuyau extérieur (26), passe par la zone d'isolement (28). Le premier enrouleur (12) est couplé au second enrouleur (12) de façon à former entre eux un espace annulaire (32). Cet espace annulaire (32) est agencé de façon à pouvoir y amener le gaz inerte par la ligne à gaz inerte (30) du premier ou du second enrouleur. Le système comporte en outre, d'une part une vanne (36) montée sur l'extrémité amont (18) du premier enrouleur (12) de façon à pouvoir établit la communication entre la zone d'isolement (28) et l'espace annulaire, et d'autre part un système de télémesure de la température.
