Titanium alloy is widely used in petrochemical industry. This article introduces the characteristics of titanium alloy. Titanium is a new type of metal, its performance and the content of impurities such as carbon, nitrogen, oxygen, the purest titanium iodide impurity content is not more than 0.1%, but its low strength, high plasticity. At present, it is widely used in the petrochemical industry, so what are the main characteristics of titanium alloy?

First, lower density can significantly reduce string load, especially in ultra-deep oil Wells.

2. Higher strength includes elongation strength, creep strength, fatigue strength, etc.

Three, excellent corrosion resistance, excellent corrosion resistance to seawater.

Four, a wide use temperature range, the use of conventional titanium alloy temperature from minus 269 ℃ to 600 ℃.

5. Large elastic deformation capacity, titanium alloy has high yield strength and low elastic modulus, so it is suitable for spring and other parts, and more importantly, it is suitable for extended displacement horizontal Wells.

6. Low expansion coefficient, which makes petroleum equipment more adaptable to temperature changes and reduces the internal stress of structural parts.

Eight, better processing performance, titanium alloy usually has good casting, forging, welding, 3D printing and other technological performance, which is often an important factor in the selection process of various engineering can win.

Titanium alloy tubes, flanges, various bolt fittings and so on are more and more widely used in the petroleum industry at present. With the improvement and improvement of various titanium technology and technology, various titanium alloy material oil casing and other equipment will be more and more widely used.
