Mar 31, 2021 · The ERW steel pipe & tube rolling mill is a series of pipe machines, which use a certain width of steel strip to manufacture longitudinal welded pipes. The erw steel pipe production line is to form various metal pipe raw materials (plain carbon steel, aluminum, stainless steel, non-ferrous metals, etc.) through extrusion deformation and other means (round pipe, square pipe, special-shaped pipe, etc.), using resistance welding technology for welding, sizing the welded pipe
HG168 ERW High Frequency Welded Steel Tube and Pipe Cold Forming Machine Production Line. The mill is intended for manufacturing round pipe of 60mm-165mm with thickness of 2.0mm6.0mm 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
ERW273 Pipe Production Line ERW Carbon Steel Tube Mill HG273 high quality Steel Tube Mill Pipe Machine Production Line. The mill is intended for manufacturing of round pipe of 12-50mm with thickness of 0.5-2.0mm 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, cooling,
Automatic tube mill pipe making machine price carbon steel pipe welding machine. This mill is intended to manufacture round pipe,square pipe, rectangle pipe, structure pipe as customer advise. The production pipe is straight welding pipe,welding by High frequence Solid state Welder (for example Thermatool welder).Material is steel strip,steel coil. Pipe Production Range from 8~ 630,
ERW Carbon Steel Tube Production Line - HNGK ERWStraight seam welded pipe mill also is called ERW mill. The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The edge of the steel plate is melted by making use of the proximity effect and skin effect of high frequency current.
