    Welding pipe machine line is complete equipment for welding steel pipes. It rolls the strip or plate then welds the tube to steel pipes by welding or submerged arc welding. Welded pipe making machine is composed of uncoiler, leveling machine, butt welder, loop, straightening machine and high frequency equipment.
    Working Flow
    {steel strip} — un-coiler — (opener & straightener & pincer & leveler) — strip-head shearer & butt welder station — vertical cage accumulator or horizontal spiral accumulator loop — forming M/C (main driving unit + flattening unit + breakdown section + fin pass section +seam guiding stand + high frequency induction welding  system + squeeze welding roller stand + outside scarfing unit + horizontal ironing stand) — emulsion cooling section — sizing M/C (main driving unit + sizing section + speed testing unit + straightener + pull-out stand) — CNC flying saw under computer control — conveyor table.

    Technical specification
    1.Single-head hydraulic unwinding machine: This equipment is located at the forefront of the unit. When in use, the tape coil is put on the coil head, the coil head is tensioned, and the strip steel is passively pulled into the equipment for production.
     Steel strip roll width: 350-720mm;
     Steel strip coil weight: ≤8T
     Outside diameter of steel strip coil: ≤φ1800mmStructural form: Cantilever single cone hydraulic expansion and contractionRoll head expansion:φ460 ~φ520mm (can be customized according to customer requirements)
    2.Feeding trolley: located under the coiler of the unwinder, used to transport the strip to the coiler.
    3.Seven-roller leveling tractor: It is used to pull the strip from the uncoiling machine and to the welded pipe host.
    It consists of a power part, a main part, a shovel device, an auxiliary unwinding pressure head and the like.
    Power part: reducer, motor, etc. The host part is composed of machine base, frame, two pinch rollers and five leveling rollers, sliding shaft seat, pinch traction roller hydraulic lifting and pressing mechanism, etc., active roller and gear The box shaft is connected by a clutch;The shovel board device can swing up and down, and retract back and forth.
    4.Hydraulic shearing butt welding machine: The gantry hydraulic pressure plate is used to press the strip head and the strip tail for welding. There are manual adjustment centering devices before the scissors and after the welding platform to facilitate the alignment of the strip head and tail and prepare for welding. The strip pressing plate is hydraulically pressed for easy welding. The platen is equipped with an automatic wire feeding device. The ball screw is driven by a motor to drive the slider to move back and forth. The welding gun is fixed on the slider, and the proximity switch is used to control the arc starting and stop of the welding gun. The welding torch moves evenly and the welding seam is smooth and flat.
    5. Ground cage spiral looper: This equipment stores a certain amount of strip steel, which is used for continuous high-speed production (including hydraulic pinch rollers, beaters, motors, etc.) when the equipment is docked with strip steel.
    The looper of this machine is 8 meters in diameter and the filling speed is 120m / min.
    Floor cage spiral looper & unrolling to looper floor plan
     
    6.Main machine forming section: seven-roller leveling + eight flat-rollers + eleven vertical rollers + eight gear boxesHost sizing section: five flat rollers + five vertical rollers + five gear boxes (including speed measuring roller device)
