Filter chloride ion content problem
Thread Content
I received a user data sheet and it was stated that considering the chloride ion corrosion situation, the chloride ion content is 1200mg/L. The barrel and head of the filter equipment are made of S30408 material. Should it be more secure to replace it with 316? Is there any basis for this?
look at this picture: In fact, it is better to use duplex steel.

Looking at this picture, the poster’s condition still lacks a PH value. Where does this picture come from?
Slightly better, if the liquid is in a long-term stagnant state, it is best to use duplex steel. If it is in a large flow state, ordinary stainless steel can also be used.
In the case of large circulation, heat exchangers are generally the only option, but is it possible to use 316L under such conditions?
It was also provided by Haichuan Haiyou. I don’t know the specific source {:1_90:}
Not for filters? For example, ordinary 304 can be used for 3 years, and 316l can be used for 6 years.
Who can guarantee how many years it will last? It is unreasonable to choose 316L under such working conditions. The attached picture gives you some data for reference.
