Clamping System: The clamping shoe adopts an asymmetrical design. The lower clamping shoe is designed at 120 degrees to ensure accurate flattening of the pipe. The upper clamping shoe is designed at 60 degrees for better clamping. Stepper system: The stepper system adopts a counterweight design and a double gear box structure. Frequency conversion speed regulation achieves fast stepping to meet various pipe flat head speed requirements.
3. Φ165mm Double-Station Hydraulic Press
Overview
This equipment is located in the finishing section of a straight seam steel pipe production line and is used for offline hydraulic testing of straight seam welded steel pipes.

4. Process Flow:
Quantitatively loaded pipes → To the flushing station → Roller conveyor → Flushing → Pipe end alignment → Chain bed moves at fixed intervals to the hydraulic press center → Fixed and movable test heads extend to seal both ends of the pipe → Clamp → Fill with low-pressure water and exhaust → Close flush and exhaust valves → Pressurize → Maintain pressure → Pressure relief → Fixed and movable test heads retract → Clamp and release → Pipe delivery → Lift and lower to empty water → Quantitatively pump out → Next cycle.
