Geological drill rod Φ33.5 (087)

Geological exploration drill pipe is used in coal mine for water, gas and geological exploration drilling .Geological exploration drill pipe made in our company, also called outer flat drill pipe or round drill pipe, geological alloy pipe and coal tunnel conventional drill pipe, contains oil exploration drill pipe with the diameter below 89 mm and DTH drill pipe and water well drill pipe. Drill rod body selects high quality alloy steel, and the joint selects high quality alloy structural steel. Thermal refining in vacuum greatly improves fatigue strength and shear strength. By advanced friction welding craft, drill pipe has high bending strength.welding firm, etc. Production equipment adopts advanced CNC processing equipment, ensuring high efficiency stable quality. To meet the requirements of deep hole drilling on straightness, the product has high fatigue strength and longer service life.
