Titanium alloys in the chemical industry - help develop customers

We provide high quality titanium materials to customers in the chemical industry, excellent metal performance is the customer's first choice!


Titanium alloys in the chemical industry - help develop customers

In petrochemical industry, chemical fertilizer, acid and alkali, sodium, chlorine gas and sea water desalination industry, titanium and titanium alloy can be used for manufacturing heat exchanger, reaction tower, distillation tower, washing tower, synthesizer, autoclasts, valves, catheters, pumps, pipes and so on.


Titanium alloys in the chemical industry - help develop customers

In terms of consumption, the amount of titanium used in the chemical industry is very large, because titanium and titanium alloy in many acid, alkali, salt medium has excellent corrosion resistance, but also has the advantages of light weight, higher than the strength, so in the chemical industry, petroleum, Marine engineering and other fields are widely used. Although the cost of titanium is higher, it is still cost-effective and can bring significant economic benefits in terms of life cycle, strength and environmental impact. There are five main aspects in the chemical industry:

(1) soda industry

Soda ash, the scientific name is sodium carbonate, it is one of the basic chemical raw materials, the market demand is very large. Ammonia alkali method or combined alkali process equipment will be sodium chloride and ammonium chloride and other media of strong corrosion, if the use of steel or stainless steel, you have to often replace the equipment, often stop production maintenance, a big loss, and with titanium more than 5 years intact, the titanium material with good value. In the past, carbon steel was used in the external cooler used in soda industry to cool crystallized ammonium chloride mother liquor, and the service life was only 1 ~ 4 years, while the corrosion rate of titanium was only 0.001mm/ year. At least for decades.

(2) chlor-alkali industry

Chlor-alkali industry is to use the salt we eat through electrolysis to produce sodium hydroxide and chlorine products, such as hydrochloric acid and sodium hypochlorite. Sodium hydroxide is the main raw material in papermaking industry, and sodium hypochlorite is widely used in disinfection. Used with graphite electrode as insoluble anode electrolytic, appeared many problems in the actual production, for example, because the graphite is not resistant to corrosion, high temperature and salt water makes its service life generally just 4 ~ 9 months, also because of the corrosion of graphite anode caused by polar distance increases gradually, power consumption will increase, because the graphite has been eroded away, into the lye, reduce the quality of the lye.After replacing the titanium anode, it is resistant to high temperature salt water corrosion, with excellent electrical conductivity, small change in polar distance, stable tank voltage, and the service life of the anode can reach more than 10 years. And the quality of lye has been improved obviously. Comprehensive performance improved substantially.(titanium anode is the titanium tube through the same size as the inner diameter of the pure copper rod, rolling method and then processed into a variety of shapes, cut into a certain length, and then sealed with titanium on the end of the line.)So titanium anodes are used a lot in this industry.

(3) bleaching powder industry

Bleaching powder is one of chlorine products, which is widely used in textile printing and dyeing industry. The equipment for the production of bleach powder is in contact with strong corrosive media such as wet chlorine gas and hypochlorite, so the corrosion problem is very serious, the equipment maintenance workload is very large, often stop production for maintenance, the operating rate of general enterprises is very low, especially the horizontal arm and scraper of the reaction tower, the corrosion is very serious.

After the use of titanium cross arm and titanium scraper, the operation is good, the effect is very significant, has achieved good economic benefits, maintenance and replacement equipment costs significantly reduced, bleaching powder production significantly increased.

(4) urea industry

Urea is one of the main chemical fertilizers, which is a kind of high quality and efficient nitrogen fertilizer. Urea production scale is large, in recent years at home and abroad of urea synthesis tower corrosion problem is very big, in the past using stainless steel material to make synthetic tower, the local corrosion problems, and use within 190 ℃ temperature limits, more than the temperature corrosion speed will multiply, this limits the synthesis temperature, urea is urea conversion rate is very low, the use of pure titanium lining of urea synthesis tower, not only can solve the problem of corrosion, but also increase the conversion rate of synthesis of urea. Gas strippers, decomposition systems, reciprocating high pressure ammonium methylate pumps, and pressure reducing valves in urea production facilities are now made of titanium.

(5) other chemicals

Chemical industry also within the amide, maleic anhydride, propylene, acetone, terephthalic acid, acetaldehyde and many other varieties, production equipment is also widely used in titanium materials, mainly with titanium plate and titanium tube production equipment in the reactor, and connecting pipes. And the service life of reaction kettle is certain, update is very frequent, some reaction axe head is very big, a several tons or dozens of tons, in addition, in the treatment of the corrosive substances such as nitric acid. Organic acid, hydrochloric acid, hydrogen sulfide, such as titanium and extensive use of the container. Heat exchanger. Tank. Blender. Cooler and pipeline system, so the global chemical industry manufacturer of pressure vessel is very much, every year consumes huge amounts of titanium plate and titanium tube.
