At present the titanium alloy has been widely applied in exploiting and producing oil, natural gas and in the geothermic industry, mainly used to make drill pipe, offshore platform bearing derrick, underground tubing, stress joints, oil well repairing carriage, offshore platform tension assembly, deep water separating tubing, pressure well pipe line and output pipe riser.

The titanium alloy drill pipe has excellent physical and mechanical properties, such as high strength, low density, good inherent bending property, high anti-fatigue strength, high anti-erosion property, good durable / anti-fracture property, low coefficient of thermal expansion, high melting point, non-magnetic and also high anti-quake strength, which prevents while-drilling jars from being equipped along with the titanium alloy drill pipe. With extremely strengthened anti-corrosion and anti-mine environment adaptability, the titanium alloy drill pipe can work in the high-temperature sulfurated hydrogen acid high corrosive environment .
