Titanium alloy drill pipes have excellent physical and mechanical properties, which are mainly manifested in the characteristics of high strength, low density, good inherent winding properties, and so on. Because titanium alloy drill pipes have high vibration resistance, they do not need a while drilling jar. Titanium alloy drill pipe has strong anti-corrosion resistance and adaptability to the downhole environment and can work in high-temperature hydrogen sulfide acidic and high-corrosive environments.
Gr23 Ti-6Al-4V ELI Titanium Pipe alloy drill collars and titanium alloy drill pipes have the following characteristics:
1. Non-magnetic, titanium, and titanium square bar alloy have non-magnetic characteristics. Under the condition of 20 Oersted, its magnetic permeability is 1.00005~1.0001H/m, and it will not be magnetized even in a very strong magnetic field;
2. Lighter specific gravity, titanium, and alloy are 43% lighter than steel;
3. The modulus of elasticity is small. The modulus of elasticity of titanium alloy is 57% of that of steel.
