Overview
Our High Duty ERW Pipe Mill Strip Flattener (also known as a strip leveler) is an essential entry‑section unit for complete ERW tube mill lines. Installed right behind the uncoiler, it pre‑processes steel strips ahead of forming and welding procedures. Specially designed to eliminate coil‑set curvature, edge waviness and residual internal stress from hot‑rolled and cold‑rolled steel coils, this flattener delivers uniformly flat strip feedstock for downstream tube forming, greatly stabilizing weld seam quality and minimizing pipe reject rates.
Built for carbon steel, alloy steel and galvanized steel strips, our ERW flattener is equipped with heavy‑duty hardened leveling rolls and adjustable pinch rolls. It enables synchronized automatic operation with the uncoiler, shear‑butt welder and strip accumulator within the full ERW pipe production cycle. Hydraulic pressure adjustment supports rapid parameter switching for different strip thickness and width, suiting various ERW mill capacities and OCTG pipe manufacturing requirements.
Boasting a heavy‑duty welded frame structure, the machine allows easy roll replacement and routine maintenance to sustain long‑term non‑stop heavy‑load operation. Custom‑built configurations are available to fit your actual strip specifications and site layout. Feel free to contact us for 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.
