Titanium alloy valve has a unique physical and chemical corrosion resistance

Titanium and titanium alloy valves valve because of its unique physical and chemical corrosion resistance, in the nuclear titanium check valve industry, aerospace, aviation and civil applications in areas such as chemical industry plays an irreplaceable and excellent value for money is widely used in demanding a special process line titanium pump control to ensure long pipeline safety technology, stable and reliable operation. Titanium in the civilian industry, because of its material has antioxidant and reducing media medium excellent corrosion properties, especially anti-stable above 100 ℃ reducing hydrochloric acid and sulfuric acid, phosphoric acid, acetic acid, can Titanium sheet not be compared with other materials, excellent resistance to corrosion resistance, titanium alloy valves and alloy valves are widely used in the harsh conditions of corrosion engineering.

Titanium alloy valves mainly using titanium metal material

Titanium valves and titanium alloy valve is the use of titanium metal materials in highly corrosive environments oxide film has good stability and self-passivation capability, this feature titanium valve to resist corrosion and strong variety of harsh conditions. Titanium valves can resist corrosion media environment, the key lies in the surface of the "blunt oxide film" chemical stability in corrosive media. Shanghai VINCI valve on the surface of titanium ion modification, anodizing and other scientific methods to ensure VINCI too valves in reducing medium corrosion resistance and surface hardness of quality assurance. Nickel and nickel titanium alloy valve Titanium alloy valve condition medium corrosion resistance targeted, high application cost, are widely used in chemical, petrochemical, metallurgical, nuclear, ocean development, power plants and other industrial fields pipelines desulfurization control system, to solve the general stainless steel and other metals, non-metallic materials corrosion problems can not be resolved titanium pumps to ensure the pipeline control titanium alloy valve in extremely harsh corrosive medium and long-term safe, reliable and stable operation. Shanghai VINCI valve production of nickel and nickel titanium alloy valve are: pure nickel valves, nickel-chromium alloy valves, nickel-copper alloy valves, nickel-molybdenum alloy valves, nickel-chromium-molybdenum alloy valves.

Do not be easily equipped with titanium alloy products

We are talking here not easily equipped with titanium products, titanium does not mean that the product can not Titanium alloy sheets be equipped with , but a lot of people equipped with the jewelry made ​​of titanium alloy can not be taken down , because titanium is too hard , the general cut cutting tools are no way to get titanium .     If you must wear a titanium valve jewelry sizes must be clear , and whether the case does not, who do not take down . So we are here to say do not easily equipped with titanium alloy products .

Research and application of aerospace titanium castings

Development needs of aero engine high performance led development leads the high temperature titanium alloy, titanium alloy using the temperature gradually increased, from twentieth Century 50 to alloy as the representative, through to the alloy as the representative of the. At present, represents the international advanced high-temperature Titanium alloy sheet has USA, Britain, Russia and China. Composition and performance features of high temperature titanium alloy. The existence of titanium alloy problems and development direction at aerospace titanium castings present, except for some typical titanium alloy USA and Russia have been used in practice, research on titanium alloy with other countries is still in the research stage, Aerospace titanium castings type less, not unified and the flame retardant performance evaluation aerospace titanium castings method of high cost has hindered the development of titanium alloy. Through research, the author thinks that the development direction of titanium alloy is mainly: (1) standard evaluation of fire retardant properties of titanium alloy and method. Flame retardant performance evaluation of titanium alloy right is one of the key techniques of flame retardant titanium alloys, including the simulation methods and detection technology of combustion of titanium alloy. At present, the flame retardant performance evaluation method has no uniform standards, countries have adopted different methods to test. Flame retardant performance evaluation method of titanium alloy and therefore the formulation of a unified standard will effectively promote the national Titanium alloy valves exchange. (2) increase the mechanical aerospace titanium castings properties of titanium alloy. Compared with the titanium alloy, titanium alloy is poor mechanical properties, low working temperature. Research on how to improve the mechanical properties of this alloy for deeper. (3) reduce the cost of titanium alloy. Titanium alloy containing large amount of noble metal elements of V, resulting in higher costs, limiting its application. The domestic scholars have studied to replace V with Mo part of low price.
