Titanium pipe in water purification Role

The main characteristics of titanium tubes for desalination:
Density, specific strength (strength / specific gravity) is high density metallic titanium 4.51g / cm3, higher than Al and less than steel, copper, nickel. The intensity ratio of the first metal but is located, is a stainless steel three times, 1.3 times the aluminum alloy;
Good corrosion resistance ) Titanium is a very reactive metal, which is very low equilibrium potential, thermodynamic corrosion tendency in the medium is large. But in fact the titanium is very stable in many media, such as titanium alloy plate in an oxidizing, neutral or weakly reducing medium such as corrosion resistant. This is because the titanium and has a great affinity for oxygen, air or oxygen-containing medium, the titanium surface layer of dense, strong adhesion, large inert oxide film to protect the titanium substrate corrosion. Even due to mechanical wear and tear will heal or regenerate quickly. This shows that titanium is a metal with a strong passive tendencies. Medium temperature below 315 ℃ titanium oxide film 3 is always kept this characteristic, a good heat transfer performance of metallic medical titanium plate, although lower than the thermal conductivity of carbon steel and copper, but the titanium excellent in corrosion resistance, so the wall thickness can be greatly thinned , and the surface of the heat exchanger and steam condensation droplets way, reducing the thermal group, so the surface is not scaling may also reduce the thermal resistance of titanium so that the heat transfer performance improved significantly

4 good heat resistance
The new long-term use titanium spring wire or higher temperature 600 ℃.
Good chemical resistance, low temperature performance as the representative of cryogenic titanium alloy, its strength with decreasing temperature increase, but the plastic change is not large.
Tensile yield strength of its performance close to that of titanium shows its yield ratio (tensile / yield strength) high, indicating that the titanium material difference in molding plastic deformation. Since the ratio of the yield limit of the titanium and the elastic modulus is large, so that resiliency titanium molding large.

The difference between titanium and titanium alloy plates

Titanium is a refractory metal of a light metal, a density of 4.5 g / cm3, 57% only of iron. Strength titanium alloy with high strength comparable to steel, but also has good heat resistance and low temperature performance, long-term work at certain alloy between 450 ℃ ~ 550 ℃ and minus 250 ℃. Titanium has good salt tolerance classes, the ability to seawater and nitric acid corrosion, Ti-30M alloy is resistant to high concentrations of hydrochloric acid and sulfuric acid corrosion. These advantages of titanium, grade 2 titanium wire deserved to be called a "space" metal, "Ocean" and the following metal steel, aluminum metal after the third and so on.
Titanium and titanium alloy material at room temperature forming plant, due to the forming force, a small amount of deformation limit and great resilience, which gave the manufacturing process brings a lot of difficulties, especially resilient, so that the hand injury the entire amount of labor large batch production can not meet the requirements.
The hot press forming is generally used in the manufacture of seamless titanium tube metal pieces and effective process methods, this method can be at room temperature (or heated state F) molded item, reheat Shaping: pull the materials can be directly used to form a heat and Hot school shape. Whether it is hot forming and heat were collapsed to form the school principle creep and relaxation of effort.
Thermoforming mainly take advantage of the softening and creep properties of the material in a heated state, and to improve the plastic to reduce and improve the molding forming force than to avoid cracking, but also reduce some rebound. Thermal Shaping mainly using the principle of stress relaxation in the heated state, in order to eliminate the springback, solve the problem of the precision of the parts due to the problems caused by springback.
In order to understand the mechanism of heat and hot forming shaped school must master creep and stress relaxation of principle. Month away, but this rationale Mrs perish only the right to development, but more with ten design chemical, atomic, gas and gas turbine boil, supersonic aircraft, spacecraft and other buildings of the structure of the product.
Titanium and its alloys as popular as the reason for the absence of aluminum, mainly due to high prices. To reduce costs, the new process for anyone conducting research abroad titanium alloys, such as electrolysis and direct reduction method, once the breakthrough will significantly decrease the cost of titanium sponge, will greatly stimulate the development of titanium grade 2 industry, we can only trace of such studies , can ensure China's titanium industry invincible. Besides the lack of significant capital investment in the processing of titanium and its alloys and titanium forming technology processing technology and applications, thus limiting the vigorous development of titanium industry.

titanium alloy plate technical requirements

titanium stockist Coatings industry will promote

Coatings industry will promote the 2011 increase production of titanium dioxide
Titanium dioxide industry and coatings industry is closely related to the upper and lower division. In 2009, buy titanium sheet the Chinese paint annual 7,554,000 t, where the amount of titanium dioxide up to 824,000 t, 10.4% of paint production.
With the development of the coatings industry, the growth of high-grade paint, coating of titanium dioxide requirements will remain double-digit growth in 2010, China's consumption of titanium dioxide coatings industry will reach 950 000 t, 2011 annual demand will be over one million t , close to 1.1 million t. Although production of titanium dioxide at current growth rates speculated that 2011 production may reach 125-150 pure titanium wire square him, but can not meet the demand for high-end quality paint industry rutile titanium dioxide, is expected to need to import 30-20 million t of rutile titanium dioxide to meet the needs of the Chinese coatings industry. China coatings industry as titanium dioxide industry has left a large space for development of high-grade titanium dioxide, titanium dioxide product structure change, development and production of high-grade titanium dioxide, to meet with automotive paint to represent the needs of the development titanium manufacturer of high-grade paint.
