Common specifications of titanium tubes

gr1 chemical composition

Titanium and titanium alloy pipes have excellent strength, hardness, low density, light weight, high specific strength, high temperature resistance, low temperature resistance, good machining performance, excellent corrosion resistance, non-magnetic and non-toxic, and good heat exchange performance ;Also has memory/superconductivity. The hydrogen storage performance is very outstanding.

1. It has strong plasticity. The elongation rate of high-purity titanium tubes can reach 50-60%, and the section shrinkage rate can reach 70-80%. Although the strength of high-purity titanium tubes is low, pure industrial titanium contains a small amount of impurities and added alloying elements, which can significantly strengthen its mechanical properties and make its strength comparable to high-strength. This means that industrial pure titanium pipes can have both high strength and appropriate plasticity as long as they contain a small amount of interstitial impurities and other metal impurities.

2. The specific strength (strength-to-weight ratio) of industrial pure titanium tubes is very high among metal structural materials. Its strength is equivalent to steel, but its weight is only 57% of steel.

3. It has strong heat resistance and can still maintain good strength and stability in an atmosphere of 500℃.

4. It has good low temperature resistance. Even at ultra-low temperatures of -250°C, it still has high impact strength and can withstand high pressure and vibration.

5. Strong corrosion resistance. This is because it has a particularly high affinity for oxygen and can form a dense oxide film on its surface, which can protect titanium from media corrosion.

TIG welding (Tig welding): TIG welding is one of the most commonly used titanium composite wire welding techniques. It uses an inert gas (such as pure argon) as a shielding gas to ignite the bend between the titanium composite cylinder and the welding rod, causing it to dissolve and form the weld.

Electron Column Welding: A high-energy beam welding technology is electron beam welding. Through the centering and liquefaction of fast electron radiation, a liquid pool is formed on the titanium composite cylinder to complete the welding. Electronic rod welding has the advantages of thin welding seams, small strength-influenced zone, and large welding seam shape.

Laser welding: Laser welding is a method of welding using laser radiation. Through the centering and rays of high-energy laser radiation, high temperatures and high-energy thicknesses are produced on the titanium composite cylinder, enabling rapid and deep liquefaction and alloying.
Particle axis welding: Particle axis welding is a technology that uses particle radiation for welding. Through the acceleration and brightness of the particle axis, high temperature and high energy thickness are generated on the composite cylinder to achieve softening and alloying.
