Pipe Drill

Durability, precision, and manageability are crucial characteristics of a high-quality Pipe Drill. Compared to typical Pipe Drill constructed from hot rolled piping, LEANOMS pipes are made from cold drawn piping, which offers a greater surface polish and tolerance. This significantly lowers the risk of scaling from the pipes getting inside the hammer, which is one of the main reasons for early hammer failure.

The end pieces' threads are heat treated for maximum tensile strength and longevity of the thread profile, and the joints are friction welded to obtain the highest level of strength. Due to the rapid and easy connection and uncoupling provided by this, drilling time is decreased in addition to extended thread life being ensured.

The Pipe Drill's diameter should be close to the hammer's diameter for optimal flushing and to lower the possibility of becoming trapped. LEANOMS standard API threads are the best option for the majority of applications.

Drill pipe includes a Pipe Drill, a pin adapter, and a box adapter, all of which have axial holes. The back end of the Pin adapter and the front end of the Box adapter are embedded into the axial hole of the rod from both ends by interference fitting. It has a shaft shoulder on the Pin and Box adapters, and the end face of the rod is connected by welding. The friction welding drill pipe is a new type of pipe. The Pin and Box adapters are connected by radial interference fit and welded from the axial end face, so the torsional strength of the DTH drill pipe is high, which can meet the drilling rig’s requirements. It has the characteristics of less investment in equipment and the light weight of welding drill pipe.

Drill pipe is the key component to connect DTH drilling tools and drilling rigs, it is an important part of DTH drilling tools. The drill pipe serves as a guide throughout the drilling process. Because the length of its service life directly affects the entire construction period, the drill pipe quality requirements are so stringent. For construction parties, choosing drill pipes with high strength, toughness and reliability can prolong the drill pipe’s service life.
