Abstract: A pipe section provided with a socket end part for accommodating a spigot end part of a second pipe section, the spigot end part having a sealing ring and the socket end part configured with an obliquely tapered part having areas of varying dimension for deforming the sealing ring to differing extent along the circumference of the sealing ring when the socket end part engages the spigot end part.

Abstract: With a pipe section provided with a socket end part (1) which is intended for accommodating a spigot end part (2) of a second pipe section, the exterior of the spigot end part is provided with a sealing ring (5), the interior of the socket end part (1) has a part (13) obliquely tapering towards the centre axis (12) of the socket end part for deforming the sealing ring (5) when the spigot end part (2) and an adjoining cylindrical part (14) are inserted into the socket end part (1). The obliquely tapering part (13) has at least two areas (15) distributed regularly over the circumference in which the angle of the obliquely tapering part (13) varies relative to the centre axis (12) of the socket end part in the circumferential direction.
