The invention provides a steam pipeline cabin penetrating part and a mounting method thereof. The steam pipeline cabin penetrating piece comprises a supporting cylinder, a first fireproof watertight cabin penetrating assembly, a partition plate, a second fireproof watertight cabin penetrating assembly, an expansion joint assembly and a sleeve assembly, and under the supporting effect of the supporting cylinder, the steam pipeline cabin penetrating piece is prevented from being axially bent; the expansion joint assembly is connected with the first fireproof watertight cabin penetration assembly and the second fireproof watertight cabin penetration assembly, circumferential rotation of the steam pipeline is effectively limited, the expansion joint assembly and the second fireproof watertight cabin penetration assembly only move in the axial direction of the steam pipeline, and thermal expansion displacement of the steam pipeline is dealt with through free movement; and secondary stress generated by thermal expansion and bending, shearing and extrusion stress generated by torsion are effectively avoided.
本申请提供一种蒸汽管道穿舱件及其安装方法。该蒸汽管道穿舱件包括支撑筒、第一防火水密通舱组件、隔板、第二防火水密通舱组件、膨胀节组件和套筒组件,在支撑筒的支撑作用下,防止蒸汽管道的穿舱件产生轴向弯曲;膨胀节组件与第一防火水密通舱组件和第二防火水密通舱组件的连接,有效限制了蒸汽管道的周向旋转,使得膨胀节组件和第二防火水密通舱组件仅沿蒸汽管道的轴向运动,通过自由移动来应对蒸汽管道热膨胀位移,有效避免热膨胀产生的二次应力、扭转作用产生的弯曲和剪切以及挤压应力。
