Entry Section, OCTG Production Line
Shear End Welder
Dedicated Shear End Welder for OCTG pipe production lines. It trims irregular sections at steel strip heads and tails, then conducts precise butt welding to connect successive coils. Welded strips are sent to the accumulator, ensuring stable material supply and non-stop operation for OCTG manufacturing lines.

Entry Section, OCTG Production Line
Flattener Machine
Our strip flattener is key pre-forming auxiliary equipment for OCTG & ERW tube lines. Installed after uncoiler, it eliminates coil set, edge camber, surface waviness and residual stress of steel strips. It delivers flat, stable strip feeding to optimize forming and welding, ensuring consistent, high-efficiency production for the whole pipe mill line.

Entry Section, OCTG Production Line
Single/Double Drum Un-coiler
Our uncoiler is a core front-end unit for welded tube production lines. It receives steel coils from loading trolleys, stably supports heavy coils and performs continuous uncoiling. The steel strip is smoothly delivered to the strip flattener and downstream stations, fully preparing materials for subsequent tube forming and manufacturing.
