The stability of the titanium pneumatic valve and the passivation ability is widely used

titanium pneumatic valve pneumatic valve mainly using titanium and titanium alloy materials in the corrosive environment oxide film has good stability and the passivation ability, working in humid atmosphere and seawater medium, its corrosion resistance is far better than stainless steel; To pitting corrosion, acid corrosion, stress corrosion resistance particularly strong; The alkali, organic chloride, chlorine, nitric acid, sulfuric acid has excellent corrosion resistance, etc. But titanium with reducing oxygen and poor corrosion resistance of chromium salt medium. Under low temperature and ultra-low temperature, still can maintain its mechanical properties, is a kind of important structural materials at low temperature.
nickel pneumatic valve pneumatic valve working condition of medium corrosion resistance and nickel alloy high performance/price ratio, and pertinence, application, is widely used in chemical, petrochemical, metallurgy, atomic energy, ocean development, industrial area, such as power plant desulphurization conveying pipeline control system, to solve the general stainless steel and other metals, non-metallic materials can't solve the problem of corrosion, ensure the pipeline pneumatic control valve in extreme harsh corrosive medium long-term safe, reliable and stable operation. Pneumatic valve
zirconium and zirconium alloy pneumatic valves because of its unique physical and chemical corrosion resistance, in the nuclear industry, aerospace, aviation, and civil application in the fields of chemical industry has an irreplaceable and excellent cost performance is widely used in special demanding process pipeline control, ensure long process pipeline safe, stable and reliable operation. Zirconium in the civilian industry, because the material has the oxidation resistance of medium and the excellent properties of reducing medium corrosion, especially the resistance to stable ℃ above the reducibility of hydrochloric acid and sulphuric acid, phosphoric acid, acetic acid, incomparable excellent corrosion resistance with other materials.
pneumatic valves for titanium alloy with high strength, good corrosion resistance and high heat resistance and is widely used in various fields. Many countries in the world is to know the importance of the titanium alloy material, carries on the research and development, and the practical application.
