This suction piping for a compressor comprises: a bent pipe section at least including a first short pipe section which is located on the most upstream side of the flow of fluid to be compressed, a second short pipe section which is connected to the suction side of the compressor and which extends in a direction different from the direction in which the first short pipe section extends, and a third short pipe section which is located between the first short pipe section and the second short pipe section and which extends in a direction different from the directions in which the first and second short pipe sections extend; and at least one partition section which extends within the bent pipe section from a position at least between the ends of the first short pipe section to a position at least between the ends of the second short pipe section and which divides the inside of the bent pipe section. The partition section is in contact with the axis of the first short pipe section at a position on the upstream side the downstream end of the first short pipe section and extends in a direction in which the partition section intersects an imaginary plane in which an inscribed circle in contact with the axis of the second short pipe section is present.
