Titanium Alloy Overview
Titanium is a highly chemically active metal. However, it exhibits exceptionally good corrosion resistance to many corrosive media. The reason is titanium and oxygen have good affinity, easily react with oxygen to generate a solid layer of dense and dense pure oxide film on the surface. In many harsh corrosive service media, the oxide film is very stable and difficult to dissolve. Even if it is damaged, it can be repaired by itself and regenerated quickly as long as there is enough oxygen. Titanium valve is mainly the use of titanium materials in strong corrosive environment oxide film has good stability and self-passivation ability, this feature to withstand a variety of harsh conditions of strong corrosion. Titanium valve can withstand the corrosion of the working medium, the pipe is the surface of the “passive oxide film” in the corrosive medium chemical stability. For neutral, oxidizing, weak reducing medium environment: “passive oxide film” itself has a very good stability. For high temperature or PH reducing reducing corrosive media, in order to improve its “passive oxide film” stability, by adding inhibitors (such as air, water, heavy metal ions and anions, etc.), such as surface ion modification Treatment, anodizing and other methods to improve the “titanium” in reducing media, corrosion resistance and surface hardness to meet the requirements.
Titanium valve application
Titanium valve in the atmosphere, fresh water, sea water, high temperature steam almost no corrosion
Titanium valves are very resistant to corrosion in alkaline media
Titanium valve resistance to chloride ion is very strong, with excellent resistance to chloride ion corrosion
Titanium valve in aqua regia, sodium hypochlorite, chlorine water, wet oxygen and other media have good corrosion resistance
Titanium valve corrosion resistance in organic acids depending on the size of the acid reduction or oxidation size
Corrosion resistance of titanium valve in reducing acid, depending on whether the media inhibitor
Titanium valve light weight (proportion 4.507) high mechanical strength, widely used in aerospace, marine vessels, military field.
Due to its high cost performance, titanium valve can resist the erosion of a variety of corrosive media. It can solve the corrosive problems that can not be solved in stainless steel, copper or aluminum valves in civil corrosion-resistant industrial pipeline. With safety, reliability, long life and other advantages. Widely used in chlor-alkali industry, soda ash industry, pharmaceutical industry, fertilizer industry, fine chemical industry, textile fiber synthesis and bleaching and dyeing industry, basic organic acid and inorganic salt production, nitric acid industry.
