Abstract
The radially deformable pipe of the invention is made up of at least two sections releaseably coupled end to end. The end of one of the sections has, over a predetermined axial length, an internal perimeter substantially equal to the external perimeter of the end of the other section, so as to form a male end adapted to be inserted in a female end. The extreme margin of the male end includes a locking bead adapted to fit in sealed manner in an internal groove of the female end behind a locking bead including the edge of this groove (9). The extreme margin of the female end is fitted into an external groove of the male end spaced from the locking bead by the said axial length.
Claims6
A pipe having a radially deformable and foldable wall made up of at least two sections releaseably coupled end to end, in which the end portion of one of the sections has, over a predetermined axial length, an internal perimeter substantially equal to the external perimeter of the end section of the other section, so as to form a male end portion adapted to be inserted in a female end portion, wherein said male end portion includes a distal margin shaped as a locking bead comprising a inextensible strand and a proximal external groove spaced from said locking bead by said predetermined axial length and wherein said female end portion includes a proximal internal groove having an inside edge shaped as a locking bead including an inextensible strand and a distal margin so that said distal locking bead is adapted to fit in sealed manner in said internal groove behind said inside edge and said distal margin of said female end portion is adapted to fit into said proximal external groove.
