FX60 High Frequency
Welding Pipe Production Line
High frequency welding machine is a strip as raw material, after uncoiling, molding, high frequency welding, eliminate overip, sizing, straightening, cutting off a series of pipe forming process to produce complete sets of equipment or a variety of circular steel tube steel pipe line.

Roll forming is used to make the strip cold bending into round billet, and the welding seam is extruded to form round tube by high frequency induction heating. Various standard tubes and square tubes are produced after sizing.
Raw material Carbon steel coil, galvanized steel coil, other hot or cold rolled steel coil.
Pipe size scope Width of raw material 60 - 240mm
Round pipe outside diameter Φ19 - Φ76mm
Round pipe thickness 0.6 - 3.5mm
Square and rectangular pipe size 15x15 - 60x60mm
10x20 - 40x80mm
Square and rectangular pipe thickness 0.6 - 3.0mm
High frequency induction welder power 200Kw
Production speed 20 - 80m/min
Total electricity power of the production line 350Kw
(1) Raw material uncoiler It’s used to support the steel strip roll and feed raw material for the production line.
1) Structure mode Double working position
2) Material tray outer diameter Φ1600mm
3) Material tray inner diameter Φ350 - Φ550mm
4) Central height 1000mm
5) Weight bearing 3000Kg
(2) Vertical material accumulator It’s used to weld together the tail of former material roll and the head of next roll to ensure the continuous production of pipes.
1) Max storage capacity 150-200m
2) Power of driving motor 5.5Kw
3) Max material feeding speed 150m/min
(3) Forming and sizing machine It’s the main equipment of the production line. Rollers can make steel strip form into pipes of variety shapes. It consists of forming part , welding part and sizing part.
1) Forming part Material feeding - Flattening - Feeding - 1 Horizontal roller - 1 Vertical roller - 2H - 2V - 3H - 3V - 4H - 4V - 5V - 5H - 6V - 6H - 7V - 7H - 8V
2) Welding part Seam direction guiding -Extruding - Welding - Weld burr removing - Polishing - Water cooling
3) Sizing part 1V - 1H - 2V - 2H - 3V - 3H - 4V - 4H - 5V - 5H - 6V - 6H - Speed measuring - Straightening
4) Driving method 160Kw DC motors transmit power to gear boxes through reducer, then gear boxes transmit power to each horizontal roller through universal shafts.
5) Horizontal frame Using gantry type integral frame. Diameter of shaft is Φ65mm and the material is 40Cr.
6) Vertical frame Adjusted through lead screw. Diameter of shaft is Φ45mm and material is 40Cr.
(4) Computer flying saw With the high precision STD control system and quick reaction of mechanical system, the cutting saw has reliable synchronization performance and high precision cutting length.
1) Error in length ±3mm
2) Power of cutting motor 18.5Kw
3) Power of driving motor 15Kw
(5) Automatic pipe unloading platform It is an unloading platform of pipes cut by computerized saw. After the pipes falling down, workers can quickly check the quality and package them for preparation of transportation.
(6) High frequency induction appliances Using the current skin effect and proximity effect of high frequency to make both edges of the material rapidly heated to soldering temperature and then weld them together. Using computer to monitor the process can provide the machine with reliable quality.
