Selection of calcium chloride solution material
Thread Content
Two operating conditions: 1) The calcium chloride concentration of the incoming water is 5000 ppm, with a pressure of 3 bar; 2) After concentration, the calcium chloride concentration is 25000 ppm, with a pressure of around 20 bar. The temperature remains at room temperature, not exceeding 40 degrees Celsius
Based on your description, it is recommended to apply Teflon ETFE (F40) as an anti-corrosion coating inside the carbon steel reactor; stainless steel reactors are not suitable due to the high pressures involved.
In such an environment, using polyaniline nanocoating for anti-corrosion purposes is sufficient; it offers excellent cost-performance and top-notch anti-corrosion properties
