High speed tube mill erw steel pipe making machine:At first, the coil is loaded at the uncoiler, then but-welding the ends of coil, delivering to accumulator. After accumulator, the strip is pulled from accumulator contentiously by fixed speed, is formed to opened-pipe at forming machine, then welded by High frequency welder, deburred, cooled, shaped and sized as round pipe and rectangular&square pipe at
Automatic High Quality High Speed Tube Mill HG32 Tube Forming Machine Erw Steel Welded Pipe Making Machine. High-frequency pipe welded machinery is the special equipment to product welded pipe of low carbon steel or low alloy steel material, that is feeding the steel belt into the machinery, turning into the tube by forming roller, then using high-frequency proximity effect and skin effect to make the tube Automatic welded steel pipe production line/ERW tube mill Automatic welded steel pipe production line/ERW tube mill sales to Mexi National standard model mainly produces the steel pipe, such as water-gas pipe, structure pipe and so on. Forming and sizing unit uses combination of FF forming and FFX forming to produce steel pipes through HF induction welding. Heating method uses HF induction or contact welding, i.e. steel pipe fed into the mill is formed into
16mm thickness erw pipe mill. F200x200 high precision high frequency welded pipe production line is mainly to product the square pipe size 80x80-200x200mm,thickness is from 3-16mm.This production line each unit equipment, full use of the domestic and foreign similar equipment, innovative design, full control with PC or computer control, advanced technology, convenient operation and maintenance, ERW426 Steel Pipe Making Machine ERW Carbon Steel Full automatic germany ERW tube mill machine ERW426 tube mill machine. The mill is intended for manufacturing round pipe of 89mm-273mm with thickness of 4.0mm12.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine,
