F200×200 High Precision Welded Pipe Production Line Welding Tube Machine
The F200×200 high frequency straight seam precision welded pipe production line is mainly used to produce electric welded steel pipes with a thickness of 2 to for round pipes and square pipes. On the basis of digesting and absorbing similar equipment at home and abroad, each single machine of this production line is innovatively designed in combination with my country's national conditions. The operation and maintenance are convenient, the design level and manufacturing quality are in the leading position in the country, and the structure and precision have reached the level of the units introduced in recent years. This unit has high processing quality and assembly accuracy, and adopts a reasonable roll pass, which can produce electric welded steel pipes with relatively high precision.

3. Main parameters of each unit
loading Car is steel welding structure, has lifting saddle and transverse car two parts.Lifting saddle is four-column guide rod type, oil cylinder lifting saddle.Transverse car is steel structures, on the car body is equipped with four wheels.the car driven by a motor, walking along on the rail which fixed in basis.
The uncoiler is of the structure of one cone. Used to support steel coil and provide raw material for production line.The machine is mainly composed of base, main shaft, rotary support, pneumatic brake device system, for expansion cantilever type.hydraulic expanding and Pneumatic driving
The straight head is main used to lead the new coil steel head feed into the flattener unit after uncoiler unit bring the coil into the working place
The leveling machine is used for leveling the steel strip head and end, makes it easy for shear and welder.
Shear &welder is used to cut the irregular ends of the strips and then connect the strips by welding.
The horizontal accumulator is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.
Forming machine. The steel strip go into the forming stand then in the forming part into a round shape, then be welded and shaped to the square.
used to precisely cut the pipe to length automatically under the condition that the pipe continuously delivered from the mill at high speed.
