Sacrificial Anode Cathodic Protection for Seawater Cooler Made of Titanium and Brass

More Information
  • Received Date: November 04, 2010
  • Took hydrogen embrittlement cracking accident at titanium pipe-mouth in the seawater cooler in Shanghai Petrochemical Company Limited for example, critical potential of titanium absorption hydrogen and appropriate potential of cathodic protection for seawater cooler made of titanium and copper were discussed. The selected sacrificial anode should meet the condition of prevent titanium absorb hydrogen and protect copper. For the purpose of applicable sacrificial anode in the Hangzhou Bay seawater coolers made of titanium and brass, pure Fe, Fe-9Ni and Fe-6Cr-4Ni samples had been studied by electrochemical test and immersion test. The result showed Fe-9Ni was the best one for anode. Fe-9Ni anodes had been used in two condensers successfully.
