What material should be chosen for a chloride ion content of 1500 ppm?
Thread Content
I would appreciate advice from experts: for a device whose medium is a mixture of sewage and compressed air in a 1:1 ratio, with a pH of 4-6 and a conductivity of 5000-7000 us/cm, and a service life of 10 years, what material should be chosen?
It is recommended to use titanium or 2205 duplex stainless steel.
Metal materials are too expensive; it’s better to choose non-metals
Whether under pressure or not: for applications without pressure, non-metallic materials should be used; for low-pressure situations, ordinary carbon steel (Q245R or Q345R) is suitable. For high-pressure applications, and if cost is not a concern, titanium or 2205 duplex stainless steel can be used.
I’m confused – why do you suggest going straight ahead without checking the sewage indicators? Anyway, just based on sewage alone, I’m unable to make a judgment.
There are too few key parameters, so it’s not possible to give recommendations. Your application requirements, operating pressure, temperature, and composition of the medium all influence the choice of material
