The machine is composed by the following elements: Double head uncoiler, hydraulic shearing and manual welding machine, Coiler feeder to accumulator, accumulator, forming and sizing mill, F5-250kw solid state H.F welde, Electric control system, CNC flying friction saw and Roll out table.
Welded pipe production line:
Fiirst strip preparation section:
The coil is prepared for unwinding, and the head and tail of the coil is butt welded. It is then fed into the looper and the strip is pulled from the looper and passed through the unit at a constant speed. The strip is formed into an open tube in the forming unit.
Second, rolling forming and welding:
It is welded into a straight seam welded pipe by solid high frequency to eliminate the water chill after the outer burr, and the round pipe and the square rectangular pipe are sized and shaped in the sizing machine. The sizing steel pipe is pushed in the Turkish head, straightened, and then sawn to the required length with a flying saw. After the steel pipe is sawed to a fixed length, it is quickly transported away from the flying saw by the output roller and pushed onto the gantry for inspection.
This production line meets the production process requirements of square tubes, rectangular tubes and round tubes. Welded pipe unit is special equipment for producing straight seam welded pipes in metallurgy, construction, transportation, machinery, vehicles and other industries. It produces cold-rolled and hot-rolled strip steel as raw materials by cold-bending forming and high-frequency welding. And square rectangular tubes. The deformation process of this forming method makes the force more reasonable, and the material deformation of each frame of the unit is more perfect. The remarkable features of the whole unit: fast, efficient, time-saving and labor-saving. Unit features: high strength, strong rigidity, four side shapes and diagonal lines are perfect, the weld can be placed anywhere on the face or corner of the square tube.
| Working Principle:For welding, it makes full use of two sciences-high-frequency current Skin-Effect and Adjacency Effect to make the current concentrate on the edge, and then the temperature will reach to the point of welding. Then we can make the sheet to pipe by rolling and make the edge melting to one.This technology has the following features:1．It supports many kinds of material like carbon steel, GI and others.
2．One machine could make a large range of pipe sizes by changing mold. 3．One machine could be used to make square pipe, round pipe by changing mold. 4．High working efficiency but low energy consuming. The power is 250KW TNGP. 5．The pipe made by this kind of machine could be used in many areas like water tube, wire pipe and others. |
