Exhaust gas supply arrangement of an exhaust gas turbocharger

An exhaust gas supply arrangement (1) to a turbine wheel (11) of an exhaust gas turbocharger (2), having

• a flange (14) for connecting to a manifold (3) of an internal combustion engine (4),
• an exhaust gas supply leading from the flange (14) to the turbine wheel (11), and
• a partition (13) which divides the exhaust gas supply into two channels (12),
• wherein, in a top view of the flange (14), a coordinate system is defined, the origin thereof lying in the center of the partition (13), the y-axis thereof following the partition (13) and the x-axis thereof being perpendicular to the y-axis, wherein the flange (14) has a rectangular base shape with two X-outer sides (15, 16) running parallel to the x-axis and two Y-outer sides (15, 16) running parallel to the y-axis, wherein at least one of the X-outer sides (15) has a reinforcement in the form of an elevation (19), and wherein the elevation (19) is formed in the center in the X-outer side (15).
