Abstract: The present invention relates to a bellows type, high temperature and high pressure flexible pipe unit having a cooling passage. The bellows type flexible pipe unit having a cooling passage, which cools a hot fluid by mixing the hot fluid flowing inside the bellows pipe with the cooling fluid, comprises at least one inlet hole perforated from the outside to the inside in one end and the other end of a bellows pipe respectively; and a cooling fluid supply unit, which makes a cooling fluid flow from the outside of the bellows pipe to the inside of the bellows pipe through the inlet hole. The bellows type flexible pipe unit prevents the temperature of the bellows pipe from increasing to the temperature of the fluid flowing inside the bellows pipe, thereby preventing the bellows pipe from being structurally vulnerable due to the dramatically lowered yield stress of the bellows pipe. Also, a straight pipe is installed inside the bellows pipe, so a groove formed inside the bellows pipe can be prevented from being contaminated by foreign materials as a fluid flows inside. In addition, due to the straight pipe, the cooling passage can maintain smooth flow of the fluid.
Abstract translation: 本发明涉及具有冷却通道的波纹管式，高温高压柔性管单元。 波纹管型柔性管单元具有冷却通道，其通过将在波纹管内流动的热流体与冷却流体混合来冷却热流体，包括至少一个从一端到另一端穿孔的入口孔，另一端 分别为波纹管末端; 以及冷却流体供给单元，其使冷却流体从波纹管的外部通过入口孔流到波纹管的内部。 波纹管式柔性管单元可以防止波纹管的温度升高到波纹管内流体的温度，从而防止波纹管在波纹管的屈服应力显着降低的情况下结构脆弱。 此外，在波纹管内部安装有直管，因此当流体流入内部时，可以防止在波纹管内形成的槽被异物污染。 此外，由于直管，冷却通道可以保持流体的平稳流动。
