HIGH PRECISION ERW TUBE MILL LINE
HIGH PRECISION ERW TUBE MILL LINE
Sinoform HG series High Precision Welded Pipe&Tube Mill line :
The process of roll forming and high-frequency resistance welding is adopted to first form and HF weld the strip steel raw material into a round tube, and then pass it through a sizing part change into the round tube or square &rectangular tube based on required size. This is the "round first, square later" production process.
HG series High Precision Welded Pipe&Tube Mill line divide into 3 type
1. HG φ8-50.8(6x6-40x40) 2. HG φ19-115(15x15-90x90) 3. HG φ48-273(25x25-200x200)

HIGH FREQUENCY RESISTANCE WELDING
HFRW can generate resistance heat through connecting welding parts by 10-500KHz high frequency current that heat up the outer surface of welding parts to become fusion and plastic state.Meanwhile two side of metal joint can be fused together by HFRW welding that is Solid State Resistance Welding technology.
Nowadays HFRW is mainly used for mechnical and pipe &tube and profile under high-level-automation field.
The material of welded parts can be steel or non-ferrous metal, tube diameter range from 6-1420mm,wall thickness from 0.15 to 20mm.Normally small dia tube adopt longitudinal welding seam.Large pipe mostly adopt spiral welding seam.
