La description

Our company's drill pipes are in accordance with API 5D, API SPEC 7 Standards. The
material of drill pipe body are chosen by the 1&3 group of API 5D.(Group *-Grade E*5;
Group *-Grade X*5, G**5, S**5).
The choice of tool joints is according to the customersrequirements, and the tool joints
are up to API SPEC7 Standards.
First, uses the double ledge attachment drill rod the reason
The ordinary API male union because attaches the thread outer diameter limit, the API drill rod has pair of contradictory: Attaches anti turns the intensity and the male union flushing port size. The S**5 high strength drill rod, the contradiction is in particular more prominent
attaches the flushing port size to increase, attaches antiturns the intensity to reduce, antiturns the strength ratio with the tube body to reduce; (2) attaches flushing port minification, attaches antiturns the intensity to increase, but the hydraulic horsepower loss increases.
How therefore both can increase the flushing port size, and can not reduce, even increases the attachment anti- to turn the intensity.
Bohai Sea can a gram company produce the double ledge attachment drill rod can solve this problem well: Both may increase the attachment flushing port size, reduces the hydraulic horsepower to lose, and can enhance the attachment anti- to turn the intensity, causes to attach anti- turns the intensity to be higher than the tube body antito turn the intensity.
