Steel drill pipe is a crucial component used in Horizontal Directional Drilling (HDD) machines for the installation of underground pipelines, cables, and conduits. It is a cylindrical, hollow steel tube that serves as the main conduit through which drilling fluids are pumped and the drill head is advanced.
Steel drill pipes are designed to withstand the challenging conditions encountered during HDD operations. They are typically made from high-strength, durable steel alloys that can withstand the stresses and forces exerted during drilling, including torque, tension, and bending
