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.
