Fast, Safe Bundle Extraction
Qingwei’s hydraulic bundle extractor enables rapid extraction and re-insertion of heat-exchanger bundles in refineries and process plants. Built for heavy duty use, the machine provides precise, controlled push-pull force and stable guidance to keep crews safe and turnarounds on schedule.
Diesel Core Pulling Machine
The diesel core pulling machine is designed for large-diameter steel pipes and profiles on cold drawing production lines. Its high-torque diesel power pack delivers strong pulling force and works reliably even in harsh outdoor environments or workshops with unstable grid power. The compact structure is easy to operate and maintain.
Key Features:
- High-torque diesel power with strong core-pulling force
- Reliable operation in harsh environments with low dependence on grid power
- Good fuel economy and strong continuous working capability
- Customizable pulling stroke and clamping method
Typical Applications:
- Large-diameter thick-wall steel pipe core pulling
- Seamless steel tube cold drawing lines
- Outdoor temporary processing sites
Electric Core Pulling Machine
The electric core pulling machine is driven by an electric motor and hydraulic system, providing smooth, low-noise operation that is ideal for indoor automated production lines. It can be integrated with loading systems, cold drawing mills and online inspection equipment to achieve highly automated or unmanned operation.
Key Features:
- Electric drive with low energy consumption and high control precision
- Optional servo control for accurate positioning
- Compatible with PLC / MES systems for line integration
- Low maintenance cost and suitable for long-term continuous production
Typical Applications:
- Automated steel tube cold drawing lines
- Core pulling for precision and alloy tubes
- Centralized indoor processing workshops
