Application foreground of titanium alloy in petroleum exploration and development

Titanium alloys have been widely used in aviation, aerospace, shipping, chemical, medical, marine engineering, petroleum and petrochemical industries because of their excellent properties, causing the global researchers expand its application development upsurge.Titanium alloy has the advantages of low density(20 ℃, 4.506~4.516 g/cm³), high specific strength, excellent corrosion resistance and impact resistance, high economy compared with other metal materials. Although the titanium alloy pipe has some disadvantages, such as corrosion resistance, corrosion potential when it was used in the field of petroleum exploration and development, titanium alloy drilling rod, oil casing pipe and transmission pipeline have been actively developed and put into trial. With the continuous reduction of the cost of titanium alloy and the development of processing technology, its application in petroleum and natural gas exploration will be more and more extensive.
