1), lower density
It can significantly reduce the pipe string load, especially for ultra-deep oil well pipes.
2), higher intensity
Including: tensile strength, creep strength, fatigue strength, etc. The specific strength of different materials at different temperatures.
3), excellent corrosion resistance
Excellent seawater corrosion resistance
Comparison table of seawater corrosion resistance (mm/a) data
4), wide operating temperature range
The service temperature of conventional titanium alloys ranges from minus 269 ℃ to above zero 600 ℃.
5) Large elastic deformation ability
Titanium alloy has high yield strength and low elastic modulus (E), so it is very suitable for parts such as springs, and more importantly, it is suitable for large-displacement horizontal wells.
6), lower expansion coefficient
This feature makes petroleum equipment more adaptable to temperature changes and reduces the internal stress of structural parts.
7), non-magnetic
Adapt to the requirements for normal use of some detection, communication, and control means in various equipment.
