A method for installing a pipe in a borehole and a pipe assembly for installation are provided which reduce the likelihood of any damage to the pipe during installation. The method for installing the pipe in the borehole includes: advancing a running device through the borehole from a proximal end toward a distal end; connecting a pipe assembly with the running device from the distal end, the pipe assembly including the pipe and a flexible sleeve surrounding the pipe; retracting the running device through the borehole toward the proximal end so that the pipe assembly moves toward the proximal end; and disconnecting the pipe assembly from the running device. The pipe assembly includes a pipe having a protective coating and a flexible sleeve surrounding the pipe comprised of a continuous length of a flexible sleeve material. The flexible sleeve may be comprised of a length of a hose.
L'invention concerne un procédé d'installation d'un tuyau dans un trou de forage et une tuyauterie pour l'installation, réduisant le risque de dommage au tuyau durant son installation. La méthode d'installation du tuyau dans le trou de sonde consiste à: faire avancer un dispositif de pose dans le trou de sonde d'une extrémité proximale vers une extrémité distale; raccorder une tuyauterie au dispositif de pose depuis l'extrémité distale, la tuyauterie comprenant le tuyau et une gaine souple entourant ce dernier; enlever le dispositif de pose par le trou de sonde et le diriger vers l'extrémité proximale, de sorte que la tuyauterie se déplace vers l'extrémité proximale; et désaccoupler la tuyauterie du dispositif de pose. La tuyauterie comprend un tuyau possédant un revêtement de protection et une gaine souple l'entourant formée d'une longueur continue de matière de gaine souple. Cette gaine souple peut être formée d'une longueur de tuyau.
