Titanium pump, use and performance of titanium alloy pump

Titanium pump, titanium alloy pump is a kind of strong corrosion resistant pump, suitable for alkali acid alkali acid pump, so it is called. Corrosion characteristic of the strong, the key lies in the metal titanium. The following are the titanium and titanium alloy material corrosion property, knew titanium pump, titanium alloy pump can use the occasion and effect. Titanium belongs to the precious metal, its relative low density, high strength, high strength ratio. There are in a particular environment and excellent corrosion resistance. Titanium alloy after after, can make its strength greatly increased (the most widely used is the TC4). (1) such as Titanium alloy valves and titanium alloy corrosion resistance of titanium material has a high degree of stability in the oxide solution, neutral or weak acid, HgC1: titanium and titanium alloy at 100 ℃ FeCl100 ℃, 100 ℃ (CuC 12 all concentration) are stable in all concentrations of NaCl, 60% AlCl2 and 100 ℃ in many other metals, titanium oxide, is stable at two oxygen ethanoic acid 100% Phenoxy Acetic Acid and 100%, so that the titanium and titanium alloy have been widely used in the solution. Titanium and titanium alloy has high stability for the oxidant solution containing ions, such as 100qC hypo sodium chlorate solution, oxygen water, gas (75 ℃), the sodium hydroxide solution containing hydrogen peroxide. Titanium and titanium alloy corrosion resistance in the wet chlorine gas than other commonly used metal, this is because the chlorine with strong oxidation, titanium and titanium alloy are stable passive in the wet chlorine, in order to maintain the blunt titanium in chlorine, need certain moisture content. The relevant factors of the critical water content and oxygen pressure, velocity, temperature, and the titanium equipment or parts of the shape and size as well as mechanical damage on surface of Titanium alloy sheet  therefore, is generally believed that the critical moisture content on the passivation of titanium in oxygen in the literature is inconsistent,, mass fraction is 0.01% ~ 0.05% can be used as the critical moisture content of titanium in oxygen, but the actual experience, in order to ensure the safe use of titanium equipment in oxygen, and sometimes the water content of 0.6% is not enough, need to be as high as 1.5%. The critical moisture content also increased with increase of temperature and air speed reducing chlorine increased. The actual operation experience also shows that, the oxide film on the surface of titanium and titanium alloy after the destruction, require a higher water content to make titanium and titanium alloy passivation again.
