Latest news: Bohai equipped with the world's first new type of friction welded drill pipe
Get the latest news, according to Chinese Petroleum Network reported as of July 20th, the world's first all type of friction welding of titanium alloy rod can overcome the drill pipe company successfully rolled out in Bohai by the Bohai test equipment, technical performance and quality indexes meet the design requirements, marking the Chinese into the production of high quality titanium alloy pipe full time.
This model for BHTG105 titanium alloy pipe, joint and pipe material for titanium alloy, creatively change the current foreign titanium alloy drill pipe adopts conventional steel pipe joints and titanium alloy drill pipe is integrally connected with drill practice with cold assembly mode, connected by advanced friction welding, breakthrough the tube body problem of heat treatment and pipe joint friction welding technology of titanium alloy end upsetting, thickened tube.
Compared with the same specifications of steel pipe, BHTG105 titanium alloy pipe weight decreased by 43%, the elastic modulus decreased by 43%, with low density, good toughness, no magnetism, anti fatigue and long service life, high corrosion resistance, can work in the radius of curvature is less than 30 meters short radius horizontal wells. In air environment, fatigue life is 10 times of steel drill pipe, and fatigue life is 100 times of steel drill pipe in corrosive environment. The corrosion resistance at ambient temperature below 330 degrees Celsius, completely resist corrosion of hydrogen sulfide, carbon dioxide and chloride ions have special properties such as BHTG105 titanium alloy pipe, suitable for high corrosion wells, ultra short radius horizontal wells, deep and ultra deep wells use.
Bohai nenk pipe is the first domestic company to produce top, import substitution "production of high-quality high strength pipe enterprises, BHNK brand new drill its R & D and production, is the longest horizontal wells, Asia's first deep exploration and pipeline across the world record made special contribution.
The development and success of BHTG105 titanium alloy drilling rod indicates that the technology of R & D and manufacturing of Bohai titanium alloy drill rod is at the international advanced level and has a broad market prospect.
