US 20080191469 A1Abstract
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.
1. Pipe section provided with a socket end part which is intended for accommodating a spigot end part of a second pipe section, the exterior of the spigot end part being provided with a sealing ring and the interior of the socket end part, viewed from the end edge, having a part obliquely tapering towards the centre axis of the socket end part for deforming the sealing ring when the spigot end part and an adjoining cylindrical part are inserted into the socket end part, the part of the socket end part obliquely tapering towards the centre axis having at least two areas distributed regularly over the circumference in which the angle of the obliquely tapering part varies relative to the centre axis of the socket end part in the circumferential direction, in such, a manner that in each area, along the sides of the area, the obliquely tapering part, viewed in the circumferential direction, is at: a first angle relative to the centre axis of the socket end part and, in the centre of the area, is at least partly at a second angle relative to the centre axis of the socket end part which is smaller than the first angle, characterized in that, between the sides and the centre of each area, the obliquely tapering part, is at the first angle in a part which is situated on the side of the end edge of the socket end part and at the second angle in an adjoining part on the side of the cylindrical part of the socket end, part relative to the centre axis, the axial length of the part at the second angle gradually increasing from the sides towards the centre of the area.
2. Pipe section according to claim 1, in which the obliquely tapering part is at the second angle relative to the centre axis of the socket end part in the centre of each area with a varying angle.
3. Pipe section according to claim 1, in which there are areas between the areas with a varying angle in which the obliquely tapering part is at the first angle relative to the centre axis.
4. Pipe section according to claim 2, in which there are areas between the areas with a varying angle in which the obliquely tapering part is at the first angle relative to the centre axis. Description
The invention relates to a pipe section provided with a socket end part which is intended for accommodating a spigot end part of a second pipe section, the exterior of the spigot end part being provided with a sealing ring and the interior of the socket end part, viewed from the end edge, having a part obliquely tapering towards the centre axis of the socket end part for deforming the sealing ring when the spigot end part and an adjoining cylindrical part are inserted into the socket end part, the part of the socket end part obliquely tapering towards the centre axis having at least two areas distributed regularly over the circumference in which the angle of the obliquely tapering part varies relative to the centre axis of the socket end part in the circumferential direction, in such a manner that in each area, along the sides of the area, the obliquely tapering part, viewed in the circumferential direction, is at a first angle relative to the centre axis of the socket end part and, in the centre of the area, is at least partly at a second angle relative to the centre axis of the socket end part which is smaller than the first angle.
It is an object of the invention to provide an improved pipe section of the type mentioned in the introduction.
The invention will be described in more detail below by way of a number of exemplary embodiments with reference to the drawing, in which:
FIG. 1 shows a longitudinal view of a specific embodiment of a socket end part 1 of a first pipe section according to the invention and an associated spigot end part 2 which has to be inserted into the socket end part 1 in order to form a pipe connection between the first pipe section and the second pipe section.
Between the sides 16 and 17 and the centre 18 of each area 15, the obliquely tapering part is in a part 19 situated on the side of the end edge 11 of the socket end part 1 at the first angle α1 and in an adjoining part 20 situated at the side of the cylindrical part 14 of the socket end part 1 at the second angle α2 relative to the centre axis 12 (see FIGS. 5 and 6). In this case, the axial length 1 of the part 20 which is at the second angle α2 gradually increases from the sides 16 and 17 towards the centre 18 of the area 15.
