HGF300 high-frequency welded pipe production line is the special equipment providing longitudinally welded pipe and cold formed steel for industries such as metallurgy, construction, transportation, machinery, vehicles and so on. Used traditional square technology to produce square and rectangle pipe.Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method to produce the suitable round tube. Material of the coil: low carbon steel (σb≤500Mpa,σs≤235Mpa.)Strip Steel: Q235 (max.)
Finished product will be of round pipe, square and rectangle pipe.
The technical flow of the production line:
Feeding strip→ Uncoiler→ Peeler→ Five roll Flattening→ shear and end welder→ Spiral accumulator→ Forming → High-frequency induction welding→Removing External burr→ Polishing Roller→ Water Cooling→ Sizing→ Cutting Saw→ Pullout roller table→ Weighing and Measuring→ Painting and Marking→ Packing→ Warehousing
