【摘要】 针对某化肥厂合成氨工艺中液氨储罐,在不同时期内储罐壁厚测试值的基础上,应用ANSYS软件计算了1975年、1998年和2004年储罐的应力状态和剩余强度。预测了2010年和2016年储罐各部分的壁厚,并进行了工作应力计算和剩余强度评定。更多还原

【Abstract】 Based on the tested values of the thicknesses of the tank walls during various periods,ANSYS software was used to calculate the stress conditions and residual intensity of the tanks made in 1975,1998,and 2004 for the liquid ammonia tanks for synthetic ammonia technology in a chemical fertilizer factory.The thicknesses of each part of the tank walls in 2010 and 2016 were predicted,and work stress calculation and residual intensity assessment were conducted.更多还原
