hotselling Coal mining twist drill rod/twist rod introduction
Spiral craft: prestressed wire winding and welding with single strip steel or double strip steel, based on the big torque of geological drill rod. Material of rod body: geological alloy pipeMaterial of connector: first-class alloy constructional steelCraft: thermal refining in vacuum, which greatly improves the fatigue resistance and shearing strength. Rod body craft: friction welding, which improves the bending strength and the firmness of the drill rod. Production facility: CNC machining equipment, which guarantees the high production efficiency, steady quality and straightness.
1, Light weight (lighter than the old-fashioned drill pipe 45%) 2, Footage soon, dust small vertical holes left after drilling cuttings, into a hole clear. 3, Card beans quickly and easily connect and save banding material. 4, Under separation of body and drilling may be the end, the use of life extended. 5, Water-based wet good pass operation.
