Several characteristics of titanium alloy used in petrochemical industry

Titanium is a new type of metal, its performance is related to the content of carbon, nitrogen, hydrogen, oxygen and other impurities, the purest titanium iodide impurity content does not exceed 0.1%, but its low strength, high plasticity. At present, it is widely used in the petrochemical industry. What are the main characteristics of titanium alloy?

1.A lower density can significantly reduce the load on the string, especially in ultra-deep oil Wells.

2.the higher strength includes: tensile strength, creep strength, fatigue strength, etc.

3. excellent corrosion resistance, good corrosion resistance to sea water.

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

5. large elastic deformation capacity, titanium alloy yield strength is high and elastic modulus (E) is low, so it is suitable for spring and other parts, more importantly, is suitable for extended reach horizontal Wells.

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

7. Non-magnetic, suitable for the normal use of some detection, communication and control means in various equipment.

8. Good processing performance. Titanium alloy usually has good casting, forging, welding, 3D printing and other technological properties, which is often an important factor in the selection of materials for various projects.

Titanium alloy pipe, flange, various bolt fittings and so on are more and more widely used in the petroleum industry. With the improvement and improvement of various titanium processes and technologies, various titanium alloy material oil casing and other equipment will be more and more widely used.
