One clamping completes the rolling of an entire 12m pipe section. No segmentation, no welding joints – improving straightness and weld quality. Dedicated for large-diameter LSAW pipes and long-distance pipelines.
High-precision forming ensures accurate pipe dimensions, reducing rework and improving welding pass rates. Solid forged 42CrMo alloy steel rolls with hardness HB260–280 provide precision grinding without scratching or deformation.
Siemens PLC with touch screen and 8-axis all-digital control featuring absolute displacement sensors ensure precise positioning and fast response. User-friendly controls enable new operators to learn quickly and work efficiently.
Heavy-duty frame with box-type welded Q345B thick steel plate, stress-relief annealing, and precision machining withstands 1,800T rolling force with no deformation under long-term heavy load. Ensures stable continuous operation across 2–3 shifts.
All three work rolls are driven by full hydraulic motors. Low-speed, high-torque transmission ensures smooth and impact-free operation. Thick plate rolling is stable with no slipping and no trembling.
Built for large-diameter LSAW pipes, long-distance oil/gas pipelines, pressure steel pipes, and steel pipe racks. Handles X42–X70 high-strength steel. Integrates rolling, beveling, auto loading/unloading, and continuous forming.
Stable and efficient, it is the foundation of pipe production accuracy.
