ERW stainless steel pipe welding machine, 32 High-Frequency Welded Welding Machine is able to produce welded pipes of Φ12.7-Φ50.8mmm in diameter and 0.7~3.0mm in thickness. Correspondingly, the Line can also produce all kinds of profile pipes, like square/rectangular/oval pipes and other shapes of pipes. Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling.

Forming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.

Process

Coil Loading → Uncoiling →Cutting and Welding → Accumulator → Forming, HF welding, Deburring,Cooling, Sizing, Straightening →cutting saw →Transmitting → Packing → Storage

We can make the pipe is round pipe,oblate pipe,the Rectangular pipe,square pipe in one machine with different sizes.
