["最近遇到一个焦化废水的处理项目，由于焦化废水中含有Cl等腐蚀离子，因此材料选择非常慎重。但有一个废水预热器，冷热侧的材料通常都选择碳钢比不锈钢更适合吗？请大家多多指教。

碳钢不比不锈钢耐Cl腐蚀，仅仅是CL盐的话应该寿命也不会不长，最好最好用钛。

理论上如此据我了解现场一般CS都选择碳钢，所以才不解。

看成分和浓度另外有些公司做的设计选材不一定合适，特别是k环保公司，我有个废盐水处理项目就被坑了，主要设备都换过了

钛材太贵不如试试我们的7无机防腐涂料

估计是节约成本的因素一般这种预热器都是管程5壳程3或316

主要是材料太贵3这种情况下容易孔蚀漏，3年修又麻烦报废成本太高。做碳钢的顶个3这种年直接报废 kuk
