Products Usage:
Drill pipe is used in the drilling. It's a major drilling component which connects rotary system, hoisting system, circulation system with drill collar and bit.
Through it the rotary table drives the bit rotation, hook drives bit up and down and drill fluid flows to the well bottom forming circle to make the bit breaks rock and reaches continuous drilling.
