Abstract
The invention relates to a seal (2) between a lining pipe or liner (1) and a surrounding pipe (3), said seal being exteriorly arranged on the liner. The seal (2) includes a cavity (14), the outer wall (16) of it being expandable into engagement against the inner surface (4) of the outer pipe (3) by injecting a filler medium (16) into the seal. The latter has a lip (18) inside its cavity (14), this lip covering a hole (19) for filling medium into the cavity, said lip (18) serving as a non-return valve. The outer wall (16) of the cavity (14) has a fold (17) and the cavity is formed with its defining surfaces substantially in contact for eliminating the presence of air in the cavity before the injection of filler medium. At one end the seal (2) has a conical lip (10) provided with a waist (11), and at its other end it has a cylindrical lip (21), the end surface (12) of the conical lip (10) being intended for making contact with the inner surface (4) of the outer pipe (3), and the cylindrical lip (21) is intended to serve as a non-return valve for optional filling of filler medium in a region behind the seal. The invention also relates to a method of achieving the inventive seal (2).
