Pipe support structure

A pipe support structure for supporting a pipe supported at a first clamp position and a second clamp position, the pipe having a fluid passage formed therein to allow a fluid at a high temperature to pass therethrough, and made of a resilient material, comprises:

• a retaining member for resiliently retaining the outer peripheral portion at at least one of the first clamp position and the second clamp position,
• the pipe having an inclined portion inclined with respect to a horizontal plane perpendicular to the gravity direction, and a bent portion having a predetermined radius of curvature, the inclined portion and the bent portion being disposed between the first clamp position and the second clamp position,
• the retaining member having a predetermined spring constant and a predetermined attenuation coefficient,
• the pipe being subjected to a Coriolis force and having a heat expansion amount caused by the Coriolis force when the fluid passage allows the fluid at the high temperature,
• the retaining member having a reaction force acting against the Coriolis force,
• at least one of the first clamp position and the second clamp position and the shape of the bent portion being set, and the spring constant and the attenuation coefficient of the retaining member being set in such a manner that the reaction force of the retaining member generated in response to the Coriolis force generated on the pipe acts to suppress the heat expansion amount caused by the Coriolis force from being increased when the fluid passage allows the fluid at the high temperature.
