Lsaw Pipe Erw Pipe High Speed Tube Mill 3.5mm

• Uncoiler

The uncoiler is of the structure of double expansion and cantilever mandrels. It contains two main parts: main body and the fixed base. The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.

• Automatic shear and welder

Used to cut off the irregular part of the tape head and tail, and align the tape tail of the previous coil with the tape head of the next coil, and weld them together to continuously feed the looper.

Structural form: shear welding bed, pinch feeding device, double centering device, double shearing shearing system, shearing plate system, welding bottom plate driving system, etc.

• Spiral accumulator 4M

This machine is between shear welder and host (forming sizing mill) ,use for after a roll of strip steel are used up, before the next roll strip since prepared from uncoiling, shearing and butt welding time to ensure that the host (forming sizing mill) continuous production and store enough strip steel.

This unit is main include in press & carry material device, accumulator assemble, carry off material unit, electric control unit:

 (１) press & carry material device:It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit; it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press & carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.

(2)Accumulator frame assemble: include the electric motor, frame , inner circle roll, out circle roll and pressure roll. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.

(3)Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.

(4)specification:

• Forming & Sizing

The forming & sizing unit is the vital equipment to the pipe mill line. This unit abide by the roll frame theory. It could continue process some specification steel tube by no-contact welding, that is carrying some strip steel to this unit and let it passing the frame roll to frame tube raw, and then take the electric fluid together on the tube welding surface so as to treat the tube temperature higher to suit welding by the pressing roll welding, and then after cooling, forming sizing and flattener to product what is your demand tube.

• Cold Saw

The cold cutting saw ia able to cut tubes with speeds up to 100m/min An automatic control system allows to optimize blade positioning according to the tube diameter and thickness,setting the speed of feeding and rotation of the blades. this system is able to increase the quality of the cut surface. no burr. in the work process eliminating mechanical clearance, reduce the influence of cold cutting saw blade, saw blade small wastage, reduce the production cost. improve the machine service life.

• Hydraulic testing machine

Φ21.3～Φ48mm Four-station hydraulic testing machine

1.  Length of test steel pipe: 8～12 meters

2. Test steel pipe material: low and medium carbon steel

3. Maximum test pressure of steel pipe: 10MPa (100bars)

4. Holding time (settable): 3～5sec

5. Number of roots per test (four stations): 4 roots

6. Pressure test medium: emulsion/water

7. Low pressure water filling method: pre-filled water (low pressure pump, water storage tank and accessories)

8. Pressurization method: pressurization cylinder pressurization

9. Equipment installed capacity: ≈90KW

10. Efficiency (holding pressure 5S): The maximum production rate is 12 pieces/min (1/2″ pipe), but the air supply pressure from the air compressor to the equipment shall not be lower than 0.6Mpa;

Work process:

Upper pipe → align → chain transport to the water pressure center → clamp → fixed and mobile end test head extends to seal both ends of the steel pipe → low-pressure water fills with water, exhausts → closes the water filling valve and exhaust valve → pressurizes → Protects pressure→Relieve pressure→Retract the fixed and mobile end test head→Clamp loose→Send the steel pipe out of the chain→empty water→discharge

• Automatic palletizing machine

This machine is used to collect, stack steel pipe into 6 or 4 angles, and bundle automatically. It runs stably without manual operation. Meanwhile, eliminate the noise and knocking of shock of steel pipes. Our packing line can improve your pipes quality and production efficiency, reduce cost, as well as eliminate potential safety hazard.
