Patent ID: 7748754

Claim:
A pipe section provided with a socket end part ( 1 ) which is adapted for accommodating a spigot end part ( 2 ) of a second pipe section, wherein the exterior of the spigot end ( 2 ) is provided with a sealing ring ( 5 ), the interior of the socket end part ( 1 ), viewed from the end edge ( 11 ) of the socket end part ( 1 ), having an obliquely tapering part ( 13 ), which extends along the circumference of the interior of the socket end part ( 1 ) and is obliquely tapering towards the center axis ( 12 ) of the socket end part ( 1 ) for deforming the sealing ring ( 5 ) when the spigot end part ( 2 ) is inserted into the socket end part ( 1 ), the interior of the spigot end part ( 1 ) having an adjoining cylindrical part ( 14 ), further inwards from said end edge ( 11 ) than said obliquely tapering part ( 13 ) and adjoining the obliquely tapering part ( 13 ), the obliquely tapering part ( 13 ) having at least two areas ( 15 ) distributed regularly over the circumference of the obliquely tapering part ( 13 ), each of said areas ( 15 ) having—when viewed in circumferential direction—a center ( 18 ) and sides ( 16 , 17 ), wherein along each of the sides ( 16 , 17 ) of the area ( 15 ), the obliquely tapering part ( 13 ) is at a first angle (α 1 ) relative to the center axis ( 12 ) of the socket end part ( 1 ), and wherein in the center ( 18 ) of the area ( 15 ), the obliquely tapering part ( 13 ) is at least partly at a second angle (α 2 ) relative to the center axis ( 12 ) of the socket end part, and wherein the second angle (α 2 ) is smaller than the first angle (α 1 ), wherein in a part ( 19 ) which is situated adjacent the end edge ( 11 ), which part ( 19 ) extends between each of the sides ( 16 , 17 ) and the center ( 18 ) of each area ( 15 ), the obliquely tapering part ( 13 ) is arranged at the first angle (α 1 ), and in that in an adjoining part ( 20 ), which adjoining part ( 20 ) adjoins said part ( 19 ) on the side of the cylindrical part ( 14 ) of the socket end part, the obliquely tapering part ( 13 ) is arranged at the second angle (α 2 ), and in that the axial length (l) of the adjoining part ( 20 ) arranged at the second angle (α 2 ) gradually increases from each of the sides ( 16 , 17 ) towards the center ( 18 ) of the area ( 15 ).
