HG75 High Frequency Welded Steel Pipe Mill 16-76mm

it is designed to produce welded steel pipes ,include round pipe , squre pipe and deformed pipe.

Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling.

Double expansion and cantilever mandrels

1. double expansion and cantilever mandrels.

2. Contains two main parts: main body and the fixed base.

3. Equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.

4. Mandrel consists of four-bar linkages that could move radially at the same time.

5.The four-bar linkages in two groups are fitted on two shafts respectively. Powered by air cylinder, they expand and contract radially.

Automatis shear and welder

It is used to cut the irregular ends of the strips and then connect the strips by welding. So it can let the line runing without stop when the before coil finish

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

Round pipe:16-76mm

0.7-2.5mm

Squre pipe:20x20-60x60mm

Thickness:0.7-2.0mm

1.The finished pipes run along the Roll Table and to be automatically moved onto the Bench. Then simple Packing Machine packs the pipes in hexagon shape.

2.The simple packing machine contains container and pneumatically driven alignment equipment.

3. Motor of Roll Bench: 3KW

4. Two direction down load pipe

5. With frequency converter to control running speed.
