  • Steel Grade Difference between Drill Pipe and Oil Casing

    The steel grade of oil drill pipe refers to the grade of drill pipe steel, which is determined by the yield strength of the drill pipe steel. API (American Petroleum Institute) divides drill pipe steel grades into five grades: D, E, 95 (X), 105 (G), 135 (S). The higher the drill pipe steel grade, the greater the yield strength of the pipe, and
