Patent ID: 8622438

Claim:
A piping system that is connected to an equipment nozzle of a piece of equipment comprising: a main pipe; a first bellows that is connected to one end of the main pipe; a first pipe member that is connected to the equipment nozzle that extends from the equipment, and that is connected to one end of the main pipe via the first bellows; a second pipe member having one end connected to a side part of the main pipe; a second bellows that is connected to the other end of the second pipe opposite to the side part of the main pipe; a third pipe member connected to the other end of the second pipe member via the second bellows; a first tie rod support member fixed to an outer circumference of the first pipe member; a second tie rod support member fixed to an outer circumference of the third pipe member; tie rods that maintain a fixed distance between the first tie rod support member and the second tie rod support member; and an anchor attached to the main pipe near the first bellows as a fixed point, wherein lengths of the pipe members between the first tie rod support member and the second tie rod support member are determined so that the first bellows contracts by thermal expansion of the equipment nozzle, by thermal expansion of the first pipe member, and by thermal expansion of the pipe member of the main pipe closer to the equipment nozzle than to the anchor, and the second bellows contracts to be displaced by a contraction amount equal to the first bellows by thermal expansion of all the pipe members between the first and second tie rod support members.
