Pipe having an end portion, the inner wall of which is provided with a circumferential groove, in which a sealing means is mounted and a pipe joint consisting of this pipe and a spigot end of a second pipe inserted therein

A pipe joint comprising bell and spigot pipes, the inner wall of said bell pipe (1) having a circumferential groove (2) defining a space in which a sealing means (3) is mounted said sealing means (3) comprising a sealing ring (4) preferably of rubber, having a substantially V-shaped cross-section when undeformed consisting of at least two lip portions (6, 7), and a stiffening body (5) in cooperation with said sealing ring (4) for holding one of said lip portions in said groove (2), characterized in that the sealing means (3) has portions (6, 7, 52, 51, 51A, 51B, 51') providing a compression seal between said pipes, the lengths of the lip portions (6, 7) of said sealing ring (4) being such that both lip portions, when seen from the mouth of the bell pipe end portion, extend further into the pipe than said stiffening body (5), and in that the dimensions of said lip portions (6, 7) are such that there is more volume of lip material behind said stiffening body (5), when viewed from the mouth of the bell pipe end, than there is room for in the space defined by the circumferential groove space confined by the adjacent part of the bottom (2) of the groove, the exterior of the spigot pipe (1a) to be inserted into the bell pipe (1) the rearmost sidewall (2') of the groove and the stiffening body (5), so that the lip material in a state of compression and deformation substantially fills up said space.
