Product Description

HF ERW TUBE MILL 

HF ERW tube production line is mainly used for continuous production of straight welded pipe, using high frequency induction or contact welding, not only can produce round pipe, but also can produce not more than the processing range of round pipe, square pipe and special-shaped pipe.

Specification

Tube mill working principle

Steel tube of high frequency welding is using the skin effect of alternating current (AC) and adjacent effect, steel strip after rolling forming, the information of a cross section of broken circular tube billet, in the middle of tube billet inside near the induction coil rotating around one or a set of impedance, Impedance and tube billet was reluctant to form an electromagnetic induction loop, under the action of skin effect and the adjacent effect. A strong and concentrated thermal effect is produced at the edge of the opening of tube billet, which makes the edge of weld rapidly heated of the temp erature required of welding. After extrusion by the press roller, the metal in the molten state realizes indirect crystallization and forms a firm butt weld after cooling.

Production technology process

Prepared → Decoiler → Share and butt welder → Accumulator → Forming machine → HF welder → Burr removal device → Deburring machine → Grinding machine → Air cooling machine → Water cooling → Online UT → Sizing machine → Cutting saw → Straightenter → Beveling machine → Hydro tester → Offline UT → Packing machine

 HF ERW tube mill's Features

1. High-Speed Continuous Production: Forms and welds pipe from continuous steel strip at high speeds.
2. Automated Process: Highly automated forming, welding (typically HF or ERW), sizing, and cutting.
3. Efficient Material Use: Minimal waste compared to seamless methods.
4. Cost-Effective: Lower production costs for high volumes of standard sizes.
5. Consistent Quality: Produces pipes with uniform dimensions and weld integrity.
6. Flexible Sizing: Capable of producing a wide range of diameters and wall thicknesses.
