Pipe for transporting powder and method for transporting powder

A pipe for transporting powder comprising:

• a transport path which has a portion formed by a curved pipe and through which pneumatically transported powder passes;
• and
• a blowing path through which a gas is blown into the transport path from an opening formed on an inner circumferential surface of the curved pipe,
• wherein the blowing path blows the gas in a direction in which the gas blown into the transport path from the opening forms a swirling flow along the inner circumferential surface of the curved pipe,
• wherein the transport path has a plurality of portions formed by the curved pipes, and
• the blowing path blows the gas into the transport path from the respective openings on the inner circumferential surfaces of the plurality of curved pipes with a time difference therebetween.
