0Cr18Ni9TI.以前的老装置磨穿过。基本上在汽提蒸汽环管及其喷咀部位。

我们的在两器外面是CR5MO的 在两器里面是碳钢材质的 在容易冲刷部位加衬里防护

是的原设计是碳钢,这不也是之前小催化裂化装置出现问题,这不建设新装置提出疑问 谢谢

继续请教:为什么两器外是Cr5Mo的,两器内是碳钢的?????????????????

我们的催化装置汽提蒸汽使用的0cr18ni10ti。经常开工催化剂与蒸汽管冲刷。肯定有磨穿的时候。

记得好像是0cr18ni9的,也磨穿过。为此还做过预案,怕蒸汽波动造成气体段油气进入再生器。

基本都是不锈钢的,内有衬里,我们这还没出现磨穿的情况,但我们这喷嘴的开度调节都是有专人调节的。

楼主可以查设备图纸,那样最保险、准确。我们的装置没记错的话,沉降器里面是304不锈钢,也就是0Cr18Ni9,带耐磨衬里。沉降器外面如果是中压蒸汽一般会用15CrMo合金钢管线
