A drill pipe is a tubular steel pipe with threaded connections on
both ends. It is a critical component in the process of drilling
for oil and natural gas. The primary purpose of drill pipes is to
transmit drilling fluid (commonly known as drilling mud) and torque
from the surface to the drilling bit at the bottom of a wellbore
during oil and gas exploration and production activities.
DTH drill rods (also called as drill tubes or drill pipes) are the
mechanism to transmit impact force and rotation torque to DTH
hammers and bits, as well as offer pass for the air flow.
In principle, the lighter the rod is, the better it is for the
drilling operation. So a thinner one is always preferable than a
thicker one if other parameters were the same. While in the mean
time, the yield strength and the tensile strength must also be
taken into accounts, which means relatively rod wall thickness
would be needed to obtain enough strength. Of course, once the
thickness is rigidly requested as thin as possible to minimize the
drill string weight, there is also another method to get optimum
drill tubes that using better grade steels.
