Horizontal & spiral strip accumulators install between shear-end welder and forming mill on ERW pipe lines. They reserve steel strip to feed downstream mill continuously during coil change, strip cutting & butt welding, preventing line stops. This vital auxiliary ensures non-stop ERW tube production, reduces downtime, and improves line efficiency, product yield and overall productivity.
Shear end welder is front-end auxiliary equipment for ERW & OCTG pipe lines. It trims irregular strip ends, aligns and butt welds new & old coil ends for seamless splicing, enabling non-stop coil switching, cutting downtime and sustaining stable continuous operation of your whole tube mill line.
Entry uncoiler for ERW tube line receives coils via loading trolley, unwinds strip with expandable mandrel, feeds strip to flattener, stabilizes strip tension and prevents jamming, preparing qualified strip for forming, HF welding, sizing and OCTG casing & tubing production.
