Titanium tubes are a new kind of metal material, which have completely replaced the traditional iron tubes and steel tubes in some aspects. So, what makes it quickly spread and replace the traditional material tubes? Let's take a look at the advantages of titanium tubes.

I.Titanium tubes have high specific strength.

The density of titanium alloy is generally about 4.5g/cm3, only 60 percent of steel.The strength of pure titanium is close to the strength of ordinary steel, some high strength titanium alloy exceeds the strength of many alloy structural steel.Because of the specific strength of titanium alloy is much greater than other metal structure materials,parts with high unit strength, good rigidity and light weight can be made. At present, titanium alloy is used for engine components, skeleton, skin, fasteners and landing gear.

II.Titanium tubes have high thermal strength.

The use temperature of titanium alloy is several hundred degrees higher than that of aluminum alloy, it can still maintain the required strength at moderate temperature and can work at 450 to 500℃ for a long time. The two kinds of titanium alloys still have high specific strength in the range of 150℃ to 500℃, while the specific strength of aluminum alloy decreases obviously at 150℃. The working temperature of titanium alloy can reach 500℃, and that of aluminum alloy is below 200℃.

III.Titanium tubes have good corrosion resistance.

The corrosion resistance of titanium alloy is much better than that of stainless steels when working in humid atmosphere and seawater medium. Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong; Excellent corrosion resistance to alkali, chloride, chlorine organic articles, nitric acid, sulfuric acid and so on.

IV.Titanium tubes have good low temperature performance.

Titanium alloy can keep its mechanical properties at low temperature and ultra low temperature. Titanium alloys with good low temperature performance and very low clearance elements, such as TA7, can maintain certain plasticity at -253℃. Therefore, titanium alloy is also an important low temperature structural material.

V.Titanium tubes have high chemical activity.

Titanium has high chemical activity, and has strong chemical reaction with O, N, H, CO, CO2, water vapor and ammonia in the atmosphere. When the carbon content is greater than 0.2%, hard TiC will be formed in titanium alloy. When the temperature is higher, TiN hard surface layer can be formed by the interaction with N. Above 600℃, titanium absorbs oxygen to form a hard layer with high hardness. When hydrogen content increases, embrittlement layer will also be formed. Titanium chemical affinity is also large, easy to adhere to the friction surface.

VI.Titanium tubes have low thermal conductivity and elastic modulus.

The elastic modulus of titanium alloy is about half of steel, so its rigidity is poor, easy deformation, should not make slender rod and thin wall parts.Cutting the processing surface of the springback is very large, about two to three times of stainless steel, resulting in severe friction, adhesion, adhesion wear of the tool surface.

Titanium tubes are widely used because of its advantages of light weight, easy to use, good performance, small density and so on. It plays an important role in aircraft engines, rockets and missiles.

I.Application of titanium tubes in military industry

A typhoon class nuclear submarine, titanium tubes have a very broad use in military industry. Titanium tubes are widely used in nuclear powered submarines, hydrofoil boats, mortar barrels, anti-tank missiles, missile launchers, tank protection plates, bulletproof vests and other military equipment. According to the data, the amount of titanium tubes is as high as 9000 tons, which shows that the military industry has a huge demand for titanium tubes.

II.Application of titanium tubes in aerospace

Commercial aircraft use titanium tubes that account for about 25 percent of the weight of the frame. In addition, strategic rocket engines, spacecraft such as Shenzhou V and Shenzhou VI satellite antennas are also a large number of titanium tubes. Titanium tubes are widely used in the aviation industry.

III.Application of titanium tubes in Marine industry

Titanium tubes have the corrosion resistance that other metal materials can not compare, especially in seawater high speed erosion corrosion. At present, the United States, Japan, France and other countries have developed a variety of advanced titanium tubes for deep-diving submersible, submarines, submarine laboratory devices to study the ocean . In addition, titanium tubes equipment and devices are widely used in coastal power stations, offshore oil production equipment, seawater desalination, Marine chemical production and mariculture industry.

IV.Application of titanium tubes in Chemical

The type of equipment has developed from small and simple to large and diversified. According to the expectation of the chemical industry, the application of titanium tubes equipment have expanded from the original soda and caustic soda industry to the entire chemical industry. The annual amount of titanium tubes used in chemical industry will exceed 1500 tons. From 1970s to 1980s, China's vacuum salt manufacturing enterprises gradually began to use titanium tube metal materials manufacturing equipment, resulting in a great improvement in the corrosion of equipment.

V.Application of titanium tubes in petroleum refining

Sulfides, chlorides and other corrosive agents in petroleum processing products and cooling water seriously corrode refining units, especially condensing equipment on the top of atmospheric and vacuum tower in low-temperature light oil parts. The corrosion of equipment has become one of the prominent problems that have troubled the refining industry. In recent years, the United States, Japan and other countries have introduced titanium tube equipment into these high corrosion links, and achieved good results.

VI.Application of titanium tubes in automobile industry

Titanium tubes have been used in racing cars for many years, and their lightweight, high strength and other properties have long been concerned by automobile manufacturers. At present, almost all the racing cars use titanium tubes. Japan's automobile titanium tubes have exceeded 600 tons. With the development of the global automobile industry, automobile titanium tubes are still increasing rapidly.

VII. Application of titanium tubes in medicine

Metal implants are a rare surgical procedure, as medical technology improves. Because titanium tubes metal has weak rejection reaction with human tissue, it is widely used in artificial bone, artificial joint, artificial tooth and other human implants. In addition, the application of titanium tubes in pharmaceutical machinery and medical devices has also been further recognized, the demands of the future should not be underestimated.

VIII.Application of titanium tubes in bicycle frame

As the high strength and low density GR9 titanium alloy tube applied in the bicycle frame, it will not only make the frame light weight, high strength and more durable. The weight of titanium alloy is only 50 percent than that of steel, and its strength-to-weight ratio is 28.4 percent higher than that of chromium-molybdenum steel. The fatigue limit of titanium alloy is twice that of steel, and aluminum alloy frame cannot compare with titanium alloy frame in this aspect after being used for a long time. Its super corrosion resistance gives it a long life.Titanium alloy is used in aerospace products of high performance materials, has excellent metal material properties.It is currently recognized internationally as the most advanced and ideal material for producing high-grade bicycles for all kinds of racing and leisure use.

This month, Baoji Pengyuan Non-ferrous Metal Co., Ltd. shipped a ton of GR9,TA18 titanium alloy tubes. After more than a month of forging material, extrusion, cold rolling, degreasing, pickling, annealing, finishing, cutting and sizing a series of precision processes, in the end of the test with wooden boxes packed. Final delivery on schedule.
