摘要:
为研究高温条件下法兰接头的保温处理的问题,利用ANSYS Workbench对WN100-100RF螺栓法兰接头在400 ℃条件下的温度场、法兰应力等进行了模拟. 结果表明,未保温接头的最高与最低温度分别为400 ℃与257.16 ℃;保温接头的最高与最低温度分别为400 ℃与390.1℃;未保温接头与保温接头的最高温度均出现在法兰与接管的内壁,最低温度均出现在螺母的外侧;保温后接头的节能效率可达到94.97%. 此外,未保温接头与保温接头的最大应力分别为294.25 MPa与297.85 MPa;未保温接头与保温接头的最大垫片压应力分别为103.44 MPa与110.42 MPa. 因此,在本文设定的条件下保温措施对法兰接头密封性影响较小.
Abstract:
To study the thermal insulation of bolted flange joints at high temperature, the temperature field and flange stress of WN100-100RF bolted flange joint were simulated by ANSYS Workbench at 400 ℃. Results show that the highest and lowest temperature of the uninsulated joint are 400 ℃ and 257.16 ℃, respectively, while they are 400 ℃ and 390.1 ℃ for the insulated joint correspondingly. Moreover, the highest temperatures of the uninsulated and insulated joints appear at the inner wall of the flange and the pipe, and the lowest temperatures of them appear at the outside of nuts. The thermal energy efficiency of the insulated joint can reach 94.97 %. Additionally, the maximum stresses of the uninsulated and insulated joints are 294.25 MPa and 297.85 MPa respectively, and the maximum gasket compressive stresses of the uninsulated and insulated joint are 103.44 MPa and 110.42 MPa.Therefore, the thermal insulation treatment has little effect on the sealing behavior of bolted flange joints under the given conditions.
