TITANIUM AGAINST CORROSION AND «CORROSION PROBLEMS»

Up to 12 % of iron is annually destroyed by corrosion.
Metals get destroyed in the open air, in water and under ground. In corrosive media this process gets even more accelerated.
Metal protection costs are incredibly high.
This involves the use of additional covers and reinforcement of equipment walls, which leads to price rise for equipment and processes.
The use of traditional metals is a source of endless problems: losses resulting from corrosion, equipment shutdown for repair and production rate decline due to equipment contamination.

TITANIUM IS A NEW MATERIAL BASIS FOR THE NEW CENTURY

Is there any way to free a man from his slavery of eternal struggle with corrosion?
Yes, there is! There is not just a way, but a radical way to eradicate corrosion – through the use of titanium.
Its properties are unique:
1 Low density at high level of mechanical properties (the highest specific strength);
2. High level of special characteristics such as heat resistance, low cycle fatigue, fracture toughness, erosion and cavitation resistance, etc.;
3. Exceptional corrosion resistance in the majority of gaseous and liquid corrosive media;
4. High melting point;
5. Non-magnetism;
6. High processability, including weldability, ability for alloy formation both with light and heavy metals;
7. Shape memory effect for some of the alloys;
8. High physical properties: low modulus of elasticity, low linear thermal expansion coefficient, low heat conductivity, cold-resistance at sub-cryogenic temperatures, limited wetability;
9. Decorative properties due to wide range of surface oxidation colors;
10. High immunity to living tissues and bones;
11. High bactericidal properties;
12. High resistance to radioactive, neutron, heat, light and other types of emission, and low induced radioactivity.

EXAMPLES of replacement of equipment made of carbide materials with titanium equipment speak for themselves:
1. Four titanium heat exchangers at a chlorine plant replaced 30 old units made of other type of material;
2. Service life of titanium fittings is 5-10 times longer than traditional type of fittings.
3. Titanium coils in some media can serve for 10 years and more, while lead coils – only 10 months.
Additionally, titanium coil is nearly 20 times lighter than lead and occupies 10 times less space.
4. Resistance of titanium pumps to corrosive media is 30-60 times higher than cast iron.
5. Titanium fans used for gas vents in titanium and magnesium production operate for five years, while steel- for not more than 1-2 months.
6. Service life of titanium gas ducts is 20-30 longer than any other type of gas ducts.
7. Service life of titanium tubing for discharge of used pickling solutions numbers dozens of years,
while carbon steel rubber-protected tubing last only for 1,5-3 months.
8. Titanium tanks for chromium plating last 5-7 times longer than the tanks made of any other type of material.
9. Medical prosthetic devices made of titanium can permanently be present in the organism, while steel prosthetic devices-for only as long as 10 years.
And finally, let us advert to the Devine. If on the day Christ was born titanium plate were immersed in the sea, by now it would have become thinner by 0. 02 mm (!). For comparison, steel corrosion rate is 0.2-.25 mm per year.
Such examples expressively substantiate the advantages of titanium over any other structural and corrosion-resistant materials.

FIELDS OF TITANIUM APPLICATION

They are truly unlimited.
Among others, they include gas and petrochemical industries, power industry, and metallurgy.
Titanium is a valuable material for pulp-and paper industry.
Chlorine dioxide, used to bleach cellulose, is a very aggressive material.
Titanium is the best solution for operation in this medium.
Titanium has been efficiently used in hydrolyzation and timber industries as a material for production of caustic material processing units.
Electroplating – another field, where introduction of corrosion-resistant titanium is especially advantageous.
Titanium is used in food industry for production of process equipment.
Titanium in medical industry is the unique material for both internal and external prosthesis.

NEW VSMPO EQUIPMENT

Verkhnaya Salda Metallurgical Production Association (VSMPO) - is the world largest manufacturer of titanium and its products.
Unique combination of mechanical and corrosion-resistance properties of titanium alloys allows to manufacture reliable heat exchanging equipment with service life 10-20 times longer than similar type of equipment made of copper-containing and chromium and nickel-base alloys.
The use of such titanium properties as pit corrosion resistance, has allowed VSMPO to produce titanium tubes with the wall thickness of 0.6-1 mm. This ensures high heat transfer intensity of heat exchangers. Non-cohesion of salts and organic compounds to the walls of titanium tubes enables to maintain the preset thermotechnical characteristics during the entire service life.
VSMPO-produced titanium tubes, resistant to general and pitting corrosion and hydrogen sulphide- induced cracking, are successfully used in offshore petroleum and natural gas production. VSMPO produces tubes for geological survey and well drilling.
The range of products produced by the company is very extensive: water and steam-water heaters, heating system water heaters, oil coolers, ejector coolers, evaporators, ejectors, mixers, pump elements, fans, coils, tubing elements, scrubbers, elements of gas ducts and chimneys, condensers, and chemical vessels.
With a wide range of starting materials in place, the company can ultimately reduce the time of a unit assembly.
This allows to reduce the lead lime and equipment cost by 15-20 % compared to similar types of equipment produced by other companies.

NORMATIVE BASE

VSMPO is accredited by the Russian United Power Systems JSC for the manufacture of equipment designated for power plants.
The company holds licenses granted by the State Nuclear Supervision Organization for designing and manufacture of equipment for nuclear power applications, and permission from the State Technical Supervision Organization to develop and manufacture of pressure vessels.
Production of welded thin-walled tubes is certified.

RELIABLE PARTNERSHIP

Today VSMPO is the world leader in titanium manufacture.
The majority of the world aerospace companies has approved the quality of its products.
VSMPO holds 185 quality certificates and co-operates with 260 companies from 39 countries worldwide, including 1500 Russian partners.
High scientific potential of the company, profound knowledge of titanium alloy properties and high professionalism characterize VSMPO as a reliable supplier of equipment made from unique material, which has great future.
«Extensive application of titanium shall enable to respond to the main challenge that civilization is facing today – emancipation from slavery of Rusty Iron».
