Apparatus for freezing liquid in a fluid conducting pipe comprises a freeze jacket having two halves for releasably surrounding a section of pipe. Each jacket half includes outwardly extending flanges in abutting relationship when the jacket halves surround the section of pipe, and structure is provided on the flanges for releasably securing the two jacket halves together around the pipe. The jacket has an internal cylindrical freeze cavity adjacent the pipe and this cavity receives and retains a supply of liquid nitrogen. The cylindrical freeze cavity is defined in part by an inner two-part fixedly secured cylindrical sleeve, one half of the sleeve being associated with each half of the jacket. Insulation is positioned on the outside of each fixed sleeve half between that sleeve and an outer removable cover. Removal of the cover enables internal structural repairs and exposes the insulation for removal and replacement with new insulation.
Dispositif pour geler un liquide en circulation dans un tuyau; le dispositif consiste en une chemise comportant deux moitiés entourant une section du tuyau. Chacune des moitiés de la chemise comporte des flasques destinées à l'assemblage en about et une structure servant à fixer l'une et l'autre moitiés de chemise. La chemise comporte une cavité interne au voisinage immédiat du tuyau, cette cavité servant à recevoir et à retenir l'azote liquide. La cavité interne, de forme cylindrique, est en partie définie par un manchon cylindrique interne en deux moitiés, chaque moitié du manchon interne étant solidaire de l'une des deux moitiés de la chemise. Un matériau isolant occupe l'espace entre la paroi extérieure de chaque moitié du manchon cylindrique interne et le courvercle extérieur amovible de la chemise. L'enlèvement du couvercle permet d'accéder à l'intérieur aux fins de réparation de la structure interne ou de remplacement du matériau isolant.
