I. Summary HG60 high frequency straight weld pipe production line is used to manufacture weld steel pipe of Φ20mm-Φ60mm with 1.2mm-3.0mm of wall thickness, can produce profiled pipe also within the limit of processing round pipe. After we absorbed advanced pipe making technology from both abroad and domestic, our innovative designed production line and each single unit of the production line is not only economical but also practical. II. The Technical Flow of the Production

ERW610 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. Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method produce the suitable round tube. Material of the Coil: low carbon steel and low alloy steel (σb≤827Mpa,σs≤690Mpa.) Strip Steel: X80 Please Contact

I. Summary The mill is intended for manufacturing of round pipe of Φ12mm-Φ32mm with thickness of 0.8mm–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, further sizing or shaping and on-stream cutting of endless tube in measured lengths. Finished product will be of round,

Square to Square Forming Way Advantage: Forming square pipe directly is using the sheet material strip bending forming directly then welding and sizing. The advantage is as follows: Compared with the round-square method, the section form shape is better using this method, the relative inner radius is smaller, and the edge is straight, the appearance is clear and neat. The unit is low load, especially obvious in the sizing unit. The width of the steel strip is smaller 2.4-3%

Steel Pipe Specification 1. Pipe diameter: Ø48–Ø127mm Pipe Thickness: 1.2– 4.5mm 2. Square Pipe: 40X40mm –100X100mm Rectangle Pipe: 30X50mm –80X120mm Pipe Thickness: 1.2– 3.5mm 3. Pipe Length: 6.0m – 12.0m 4. Length Tolerance: 0-6mm Please Contact by Email at selina@tenengchina.com for much more Technical Parameters or Documents!

It’s the main equipment of the weld pipe production line, it can continuously reel the long strip steel of specific size to cylinders and welding to pipe, it can both produce round pipe and square or rectangle pipe, the mechanical unit use roll forming theory, the high frequency weld pipe can continuously produce steel pipe in specific size, the heating method use induction welding, which means feeding the specific size of steel strip into the machine, through forming roll
