ERW Tube Mill Entry Section Strip Flattening Equipment,OCTG Strip Leveler for Steel Tube Production Line

Our Entry Section Strip Flattening Equipment (also referred to as a strip leveler) functions as an indispensable entry‑section unit for complete ERW tube mill lines. Positioned immediately downstream of the uncoiler, it pre‑treats steel strips prior to forming and welding processes. Engineered to eliminate coil‑set curvature, edge waviness and residual internal stress from hot‑rolled and cold‑rolled steel coils, this flattener supplies uniformly flat strip feedstock for downstream tube forming, effectively stabilizing weld seam quality and lowering pipe reject rates.

Developed for carbon steel, alloy steel and galvanized steel strips, our ERW flattener comes with heavy‑duty hardened leveling rolls and adjustable pinch rolls. It achieves synchronized automatic operation with the uncoiler, shear‑butt welder and strip accumulator throughout the full ERW pipe production cycle. Hydraulic pressure adjustment enables fast parameter switching for varied strip thickness and width, accommodating diverse ERW mill capacities and OCTG pipe manufacturing requirements.

Featuring a heavy‑duty welded frame construction, the machine supports convenient roll replacement and routine maintenance for long‑term uninterrupted heavy‑duty service. Custom‑tailored configurations are offered to match your actual strip specifications and plant layout. Please contact us to obtain technical datasheets and quotations for your ERW tube mill project.

Our Advantages

• Precision Leveling Performance: Adopts multi-roll staggered leveling structure to apply uniform alternating bending force on steel strips, thoroughly correcting strip deformation and ensuring excellent flatness without damaging material texture.
• Stable Line Operation: Synchronizes perfectly with the full ERW production line speed, realizing continuous, jitter-free strip feeding, effectively avoiding production stagnation caused by unflat materials.
• Improve Final Pipe Quality: Optimizes strip flatness consistency, guarantees precise weld seam alignment and uniform welding, greatly reduces welding defects, pipe ovality and finished product rejection rate.
• Wide Material Compatibility: Adaptable to carbon steel, galvanized steel, alloy steel and other common pipe-making materials, suitable for various specifications of strip thickness and width, meeting diverse tube production demands.
• Durable & Low Maintenance: Equipped with high-strength leveling rolls and rigid mechanical structure, featuring wear resistance, stable operation and long service life, minimizing daily maintenance and production costs.
• Flexible Adjustable Design: Supports precise roll gap adjustment, easy parameter calibration for different raw materials and production standards, ensuring flexible and efficient production.
