Application of Titanium in the Chemical Industry Titanium and titanium alloys have better specific strength, better toughness and weld ability. More importantly, it has excellent corrosion resistance. In oxidizing, neutral medium and medium containing chloride ion, its corrosion resistance may be ten times or even several times of that of SUS304 stainless steel. Heat Exchanger with Titanium Tubes in Oil Refining Industry Titanium has excellent corrosion resistance, high specific strength and good processing properties, which has prior application in oil refining industry. In the United States, Europe, Japan, titanium has been used for 40 years, and nearly 20 years in China. The Application Scope of Heat Exchanger with Titanium Tubes The design temperature upper limit of Ti and Ti alloys is 315°C, and titanium clad plate is 350°C according to JB/T4745 "Titanium Welded Vessels". Ti materials are suit for condition with low temperature and light oil corrosion. Industrial cooling systems (including seawater, brackish water, sewage)Price and Quality are our greatest advantages!
