I would like to ask about the selection of material for the filter housing?
Thread Content
I would like to ask everyone what materials should be used for filters? Is 316L okay! Thank you! Solution composition: 3 moles of HCl (which forms sodium salts after neutralization) ； 5-10kg gelatin per batch ； A small amount of silicone ； Metal components such as cobalt and nickel
Below 100 degrees, titanium is the most suitable
Thank you! Design temperature: 80°C, treatment time: <4 hours, particle humidity: <35%. Material temperature: 50~60°C. Can the owner use 316L material if they wish? Thank you for the reply!

After neutralization, it is a sodium salt; it should be hydrochloric acid
316L is not suitable for hydrochloric acid; at this temperature, Hastelloy B or zirconium materials are required. For concentrations below 7%, titanium alloy or titanium-palladium alloy can be used
It is also necessary to check whether there is ferric trichloride or copper chloride present; if so, Hastelloy B and zirconium materials should also be avoided
Thank you very much. If the material solution is a sodium salt, what material should be used?
For sodium chloride after neutralization, duplex steel is recommended; it is not suitable if hydrochloric acid is used. Titanium alloy can also be used
