When the cycle of concentration is about 2.0 to 2.5 and the concentration of scale inhibiting dispersant XD01 is 20 mg/L, under the conditions of adding oxidation biocide liquid chlorine, the anti-corrosion properties of several materials were researched and evaluated respectively. The results showed that the corrosion resistance for sea water of titanium tube and double phase stainless steel were very good.
