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.

INTRODUCTION OF MAIN EQUIPMENT
NO. EQUIPMENT INTRODUCTION AND MAIN TECHNICAL PARAMETERSMANUFACTURER
（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 2500Kg
（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 - 5H - 5V - 6H - 6V - 7H - 7V
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 90Kw 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 Φ50mm and the material is 40Cr.
6) Vertical frame Adjusted through lead screw. Diameter of shaft is Φ35mm 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 11Kw
3) Power of driving motor 11Kw
（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.
