About the application of titanium tube

Titanium has plasticity. The high-purity titanium has an elongation of 50 to 60% and a reduction in area of ​​70 to 80%. Despite the low strength of high-purity titanium, pure industrial titanium contains a small amount of impurities and the addition of alloying elements can significantly enhance its mechanical properties, making its strength comparable to high strength. This means that industrial pure titanium tubes, as long as they contain a small amount of interstitial impurities and other metal impurities, can have both high strength and proper plasticity. The specific strength (strength to weight ratio) of industrial pure titanium tubes is very high in metal structural materials, and its strength is comparable to steel, but its weight is only 57% of steel. In addition, the titanium tube is highly heat resistant and maintains good strength and stability in an atmosphere of 500 °C. The titanium tube also has good low temperature resistance, and even at an ultra-low temperature of -250 ° C, it has high impact strength and can withstand high pressure and vibration. Another remarkable feature of the industrial pure titanium tube is its high corrosion resistance. This is because it has a particularly high affinity for oxygen and can form a dense oxide film on the surface to protect the titanium from the medium. Therefore, titanium has excellent stability in acidic, basic, neutral salt aqueous solutions and oxidizing media, and is superior in corrosion resistance to existing stainless steels and other non-ferrous metals. Industrial pure titanium tubes are widely used. At present, industrial pure titanium tubes are not only used in aerospace and aviation industries, but also widely used in many industrial sectors such as chemical, petroleum, light industry and power generation. Because pure industrial titanium tube has many excellent characteristics such as light weight, high strength, strong heat resistance and corrosion resistance, it is known as “the metal of the future” and is a new type of structural material with great development prospects.

How to improve the welding quality of titanium welded pipe

The titanium tube is light in weight, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment such as tubular heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators and pipelines. Many nuclear power industries use titanium tubes as their standard units.

Due to the high activity of the titanium tube, in the welding of the titanium tube, the welding temperature control, the protective gas protection effect, the welding environment and the like are strict, and a slight carelessness will cause a large welding quality. Impact, serious, will lead to the retirement of the product. Practice has proved that by carrying out the analysis of the main factors affecting the welding quality, the key process of welding is determined, and the control of the environment, personnel and welding parameters and methods in the welding process is strengthened, which can effectively ensure the welding quality of the titanium pipe material is further improved. Improve and prevent the occurrence of welding waste.
In recent years, a new type of titanium tube has been widely used. Because titanium alloy has the characteristics and characteristics of light weight, high strength, corrosion resistance, etc., it is widely used in the construction of pipelines for surface ships, except for a wide range of applications in aerospace, petrochemical and machinery manufacturing. However, since titanium alloy is a kind of active metal, it has great affinity for gases such as oxygen, hydrogen and nitrogen at high temperatures, that is, the ability to absorb and dissolve gases is strong, especially during welding. This ability is particularly strong with the increase in soldering temperature. Practice has proved that if the absorption and dissolution of titanium alloy and oxygen, hydrogen, nitrogen and other gases are not controlled during welding, the product will eventually be scrapped. Therefore, in the welding of titanium pipe joints, effective prevention and control must be carried out to meet the quality requirements of welding.
About weld processing:

1. The surface of the weld must be thoroughly cleaned of surface impurities such as oil, rust and moisture to prevent the occurrence of pores, cracks, etc. during welding. When cleaning, the surface of the groove should be ground with metal luster.
2. In order to obtain good mechanical properties of the weld, it is recommended to use pure CO2 for the protective gas of the weld. The flow rate of the protective gas is preferably 20-25L/min, and the dry elongation is preferably between 15-25mm.
3. The above welding methods, conditions and specifications are for reference only. Users should carry out process evaluation according to their own welding characteristics before using the welding wire for formal product welding.
