Shear End Welder
This custom shear end welder is specially designed for OCTG pipe production lines. It trims uneven deformed parts on the head and tail of steel strips, then performs accurate butt welding to link adjacent coil strips. The spliced strips are conveyed to the accumulator, securing continuous material supply and uninterrupted running of the whole OCTG pipe fabrication line.

Flattener Machine
Our strip flattener is vital pre-forming auxiliary gear for ERW and OCTG pipe production lines. Positioned right after the uncoiler, it removes coil curvature, edge bending, surface waves and residual stress from steel strips. It provides flat and steady strip input to improve forming and welding quality, guaranteeing uniform and high-efficiency operation of the entire pipe mill.

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.
