Drill Pipe Elevators for Oil and Gas Well Production

Drill pipe elevators are devices used to lift and suspend drill pipes, which are the primary pipes used to transmit torque and drilling fluid during drilling operations. They are used in drilling operations to lift drill pipes from the ground to the drill floor, or to raise and lower drill pipes in and out of the well. Drill pipe elevators typically clamp onto the tool joints of the drill pipe to ensure the safe lifting and suspension of the entire drill string.

• Features:
  • Structure: Similar to tubing elevators, commonly available in center latch or side door designs, with locking mechanisms to prevent accidental opening.
  • Load Capacity: Wide range of load capacities depending on drill pipe size and drilling depth, typically from 100 tons to 750 tons (e.g., DDZ series).
  • Applicable Pipe Diameter: Generally suitable for 2⅜ inch to 6⅝ inch drill pipes, conforming to API 8C standards.
  • Clamping Method:
    • 18° Taper Type (18° taper): Clamps the 18° external upset joint of the drill pipe, suitable for API standard drill pipes.
    • Square Shoulder Type (square shoulder): Clamps drill pipes or casings with square shoulder joints.
    • Slip-Type (slip-type): Clamps the pipe body using slips, suitable for various pipe diameters.
  • Safety Design: Equipped with safety latches or sliding sleeves to prevent accidental opening under high loads.
• Application Scenarios:
  • Raising and lowering drill pipes during drilling operations.
  • Handling drill string components, such as drill collars or casings.
  • High-load operations in deepwater drilling or complex geological conditions.
