Overview
An uncoiler is the first and core feeding equipment of a complete ERW Tube Mill Line. Also known as a decoiler, it is specially designed to hold, support and continuously release steel coil for the subsequent strip leveling, forming, welding and pipe sizing process in ERW pipe production.
Our Hydraulic Uncoiler for ERW Tube Mill Line handles carbon steel, alloy steel and galvanized steel coils with wide coil weight and width ranges. It adopts a hydraulic expanding and contracting mandrel structure to fix steel coils firmly, avoiding coil slipping during unwinding. Equipped with anti-torsion and tension control functions, this steel coil uncoiler ensures stable, smooth strip feeding and reduces material deformation, which effectively protects the whole ERW tube mill line and improves production continuity.
We supply single-head uncoiler and double-head uncoiler options for ERW pipe mills. The double-head uncoiler enables non-stop coil changeover, greatly saving downtime and boosting pipe production efficiency. Our uncoiler units are widely matched with ERW pipe making machine, steel tube forming machine and OCTG pipe production line, well received by steel pipe manufacturers worldwide.
Custom uncoiler solutions are available according to your steel coil specifications, ERW tube mill capacity and site layout requirements. Contact us to get technical parameters and quotation for your ERW tube mill project.

Our Advantages
- The two drums operate in a continuous cycle: one performs unwinding while the other handles coil loading. This design cuts downtime and boosts productivity. In addition, the drums support forward and reverse rotation to enable both upward and downward unwinding.
- A brake unit mounted at the rear of the main machine keeps the coil firmly positioned during operation.
- The hold-down roll prevents coil bounce and avoids personal injury risks.
