Titanium in the urea medium temperature and corrosion resistance of the excellent performance, riding the choice of titanium valve has become the only cost-effective choice. With the titanium valve in the urea synthesis tower export of the wide range of applications and we know the corrosion resistance of titanium material to further improve, based on enterprise management requirements of efficiency + safety without leakage, many companies will be used for a titanium pump outlet and urea synthesis Tower imports

More than 10 years of production practice tells us: titanium cut-off valve used in urea synthesis tower imports and a pump export, a installed life is generally 3 to 8 years, the optimal combination of cut-off valve is also more than 2 years, and used in urea synthesis Tower export is the titanium life of the general life of more than 18 months to titanium as the final combination of the optimal combination of the general life of about one year. The above experience tells us that urea manufacturers use titanium valves for synthetic towers export all valves is the best choice, because in a year less row of a tower, will give your business to reduce losses, ranging from tens of thousands of dollars, more than a dozen Million yuan;

Why does titanium material exhibit excellent corrosion resistance in urea-methyl ammonium solution?

First, the titanium in the urea-methyl ammonium solution allows the use of temperature than the 316L high, generally 316L to allow the maximum temperature of 190 ℃, while the titanium is allowed to 250 ℃;

Second, titanium than 316L annual corrosion rate is low, 316L annual corrosion rate of 0.05 ~ 0.5mm, and titanium corrosion rate 0.05mm, and more than 190, 316L corrosion will accelerate;

Third, the titanium oxide solution in the urea solution to produce an oxide film required oxygen content than 316L low. 316L requires oxygen content of 0.5 to 0.8% in order to generate a good corrosion-resistant oxide film; and titanium as long as the oxygen content of 0.2 to 0.25% that can maintain a suitable oxide film.

Therefore, titanium in the urea-methyl ammonium solution than the easy 316L passivation, and the passivation of a wide range, so titanium urea in ammonium urea solution 316L corrosion resistance of a higher grade.

Titanium valve due to exceptional corrosion resistance, by more and more enterprises of all ages, the use of more and more widely. But because of the high price, more significant is the use of some manufacturers choose improper manufacturers, the use of poor results, resulting in adverse effects. Titanium valve is current urea synthesis tower exports all the valves more ideal material.
