A at 200 C 楼主能保证 PV中的计算公式和水压计算公式和GB150的一致吗？PV计算还是和SW6有区别的，即使国标的材料可以自定义进去。 按照国表的计算公式不一样吧 PVELITE 2014里面收录了中国的713的Q345R 只需要在材料里面输入SA/GB就能找到对应的材料！ 感謝大大的分享!! 这个真的不会。{:1106_365:} 大侠是怎么做到的？PV里不是只有ASME材料吗？请指教！！ 说下区别吧，老大，急求！ 能普及下知识吗？这软件和SW画出来的一样吗？是面向制造的吗？还是只是一个3D图 学习了。。。{:1106_383:} ............................... 谢谢楼主无私分享 ，下来看看。 GB本来就是抄美标和欧标的！！！！
