Performance Test of Weld Zone of Rotary Friction Welding of Titanium Alloy Drill Pipe

Journal of Physics: Conference Series, 2023
Abstract With the development of complex oil and gas reservoirs, it is difficult for traditional carbon steel to meet the requirements of drill pipe materials in drilling process. Titanium alloy has gradually become a new choice of drill pipe material because of its low density and good corrosion resistance.
