Fluid piping

A fluid piping comprising:

• a piping main body that allows a fluid to flow through its inside;
• and
• a partition plate that divides the inside of the piping main body into two or more flow channels along an axial direction of the piping main body,
• the partition plate having an end surface on its upstream side, the end surface comprising:
• an inclined surface that is inclined with respect to the axial direction of the piping main body;
• and
• a gradual sloping surface that connects an end portion of the inclined surface and an inner wall surface of the piping main body.

• and
• a partition plate that divides the inside of the piping main body into two or more flow channels along an axial direction of the piping main body,
• the partition plate having end surface on the upstream side, the end surface comprising:
• a linear inclined surface that is inclined with respect to the axial direction of the piping main body;
• and
• a curved surface that is continuous with the linear inclined surface and curves in a downstream direction of the piping main body.

• the partition plate having an end surface on its upstream side, the end surface comprising:
• an inclined surface that extends from one end portion of the end surface to another end portion and is inclined linearly with respect to the axial direction of the piping main body;
• and
• a linear parallel surface that is parallel to a radial direction of the piping main body, the linear parallel surface having one end that is continuous with the inclined surface and another end that extends to the other end portion of the end surface.
