FX16 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.

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 Φ1500mm
3) Material tray inner diameter Φ350 - Φ550mm
4) Central height 1000mm
5) Weight bearing 2000Kg
（2） Shearer and butt welder 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) Shearing Responsible for shearing irregular parts of two material rolls and making preparation for welding.
2) Welding Responsible for connecting head and tail of two steel strip rolls.
（3） Vertical material accumulator It’s used to store and feed raw materials for the forming machine so that the machine can work continuously.
1) Structure mode Square pipe welded frame, pneumatic feeding, manual adjust
2) Max thickness of steel strip 1.0mm
3) Max width of steel strip 80mm
4) Max storage capacity 150-300m
5) Power of driving motor 4Kw
6) Max material feeding speed 160m/min
（4） 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
