Hilong Non-Slip-Crush Drill Pipe
Product Introduction Hilong Non-Slip-Crush (NSC) drill pipe is specially designed for solving problems such as the damage to the drill pipe body by the slip, the low operation efficiency of double-elevator, and the high labor intensity in the operation of TIH and TOH. This product adds one more shoulder positioned close to the box end based on normal API standard drill pipe. During the trip operation, drill string is set at the toothless pneumatic slip, and its weight is supported by the bearing slider of the slip along the axial direction. Besides, this product can afford a convenient way for make-up and break-out by raising its position.
Product AdvantageCompared to standard drill pipe, Hilong NSC drill pipe has advantages as follows:
·It completely avoids the slip crush on drill pipe body when associated with toothless pneumatic slip, thus extend the drill pipe service life;
· It changes from the traditional double-elevator into single-elevator in the opertation of TIH and TOH, which bring the advantage with no need for removing and hanging the elevator frequently.
At the same time, a higher box tool joint position design can lead to the make and break more convenient, lower the labor's intensity; and it improves the safety of operation;
· Improving about 15% efficiency of TIH and TOH which compared with double-elevator, reducing non-drilling time, lowering the cost of operation;
·Reducing the sticking risk of drill pipe effectively, lowering the frictional resistance remarkably.
