The bohai sea can drill pipe company was the first domestic "replace imports" with top into production, manufacturing high quality high strength drill pipe, its research and development production BHNK brand new drill pipe, longest, Asia the first exploration of deep well and horizontal well for domestic pipeline crossing a world record made special contribution.

This model for BHTG105 titanium alloy pipe, all joints and pipe material for titanium alloy, creatively and change the present foreign drill pipe with normal titanium alloy steel pipe fittings and titanium alloy pipe tube body with cold assembly way connected into a whole pipe, through the advanced mode of friction welding connection, broke the titanium alloy pipe end upset thickening, the pipe body heat treatment and body joint friction welding technology, such as problems. In the air environment, the fatigue life is 10 times that of the steel rod, and the fatigue life in the corrosive environment is 100 times that of the steel drill pipe.

All global initiative friction welding of titanium alloy pipe in the bohai sea bohai equipped to drill pipe company rolled out, by testing various technical performance and quality indexes meet the design requirements, China entered the high quality titanium alloy pipe production time.
