Hydraulic Assembly and Disassembly Frame
The Hydraulic Assembly and Disassembly is tailored to China’s current industrial conditions and requirements, ensuring proper make-up and break-out of API-standard casing, couplings, drill-pipe connections, drill pipe, heavyweight drill pipe, drill collars, and similar components. This specialized assembly/disassembly equipment is used for the removal, installation, and maintenance of various petroleum and geological screw-drilling tools, tubing strings, non-magnetic instruments, and other downhole tools.
Equipment Overview
The Hydraulic Assembly and Disassembly Frame combines cutting-edge domestic and international technologies, customized to fit China’s industrial landscape. It guarantees the accurate make-up and break-out of API-standard components. This specialized rig serves as the go-to solution for the removal, installation, and maintenance of a wide range of petroleum and geological downhole tools.
Equipment Components
The Hydraulic Assembly and Disassembly Frame consists of the following main units:
- Hydraulic Control Console
- Supplies the hydraulic power source, indicator gauges, and control levers.
- Hydraulic Clamps
- Comprises fixed and movable clamp assemblies to securely grip workpieces and apply torque.
- Hydraulic Make/Break Unit
- Applies the necessary make-up torque to tighten threaded connections and provides sufficient reverse torque (maximum rotation > 30° per cycle) to loosen them.
- Rapid Make/Break Mechanism
- Enables quick pre-tightening during make-up and fast release during break-out of threaded components.
- Hydraulic Auxiliary Support Assembly
- Features three movable, bidirectional supports mounted on the base at each end of the main frame, working with the main unit to stabilize workpieces during assembly/disassembly.
- Equipment Base
- Made up of a central main base and two extended auxiliary bases for enhanced stability.
- Tail-End Push-Pull Unit
- Performs the axial insertion or extraction of the workpiece.
