Introduction Of Main Equipment

1. Uncoiler
Function: to support and hold strip coil, the coil actively rotates combing with perching knife to peel strip and feed strip end to pinching& leveling machine
Composition: consists of feeding car, cone head uncoiler, and coil peeler.

2. Pinching& Leveling machine
Function: to level strip and feed strip to cutting& butt welding and delivery position.
Composition: hydraulic cylinder drives double roll pinching, worm gear elevator lifts five roll leveling. Lower roll actively drives under actuation of chain wheel, and feeds material driven by planetary cycloidal reducer.

3. Cutting& Butt Welding
Composition: butt welding platform can be wholly moved, consists of front& back pressing plate and butt welding platform
Function: to cut off plate head& tail, and butt weld them.

4. Vertical Roll
Composition: consists of vertical roll and its base. Lead screw drives vertical roll to adjust width, left& right.
Function: to avoid steel strip from being off center.

5. Edge Miller
Function: to mill welding groove to strip edge and mechanically collect the scrap
Composition: consists of machine device, width adjusting device, oil cylinder screw down Positioning device, driving device and tool disc.

6. Delivery Machine

Function: to offer feeding dynamic to the whole production line.

Composition: consists of machine body, speed reducer, coupling and electric motor. AC VF speed regulation

7. Pre-Bending Guide Board

Function: to pre-bend strip edge and feed strip into forming unit

Composition: consists of pre-bending device, upper& lower guide board

8. Forming Unit:

Function: to force the strip to bend as per requirement

Composition: three-roll forming, outside control roll sizing, consists of 1#,2#,3#,4#,5#,6# roll and its stand, base.

9. Front Bridge

Function: base of all equipment before forming, with the function of adjusting forming angle

10. Rear Bridge

Carrier of all equipment after forming, with the function of fine-tuning angle, cut-off and outlet pipe.

11. Buried Parts Of Host Machine:rail of host machine.

12. Flying Cutter

Function: carrier for cutting pipe to length

13. Inside& Outside Welding Device

Carrier of LINCOLN welding torch, with the function of adjusting welding torch position

14. Centralizer

To keep real bridge output in line, meantime connect with outside welder.

15. Hydraulic System Of Host Machine

Hydraulic pump station is the work system of each hydraulic device that reply on hydraulic power. It is used to supply pressure medium with controllable direction, pressure and flow to each action element (as hydraulic cylinder, hydraulic motor, etc.), to reset and achieve recycling work.

15.1 Arrangement Of Pump Station

Horizontal arrangement: motor pump group is horizontally installed on cover plate of oil tank, which mainly suits hydraulic system of good self-absorption like small displacement or small displacement variable pump.

15.2 Work Medium And Temperature

Work medium: recommend to use the anti-abrade hydraulic oil, YB-N46

Medium temperature: normal temperature: 35-60 0C, when the temperature below 15 0C or exceed 60 0C, must heat or cool till the normal temperature.

15.3 Adoption Of Hydraulic Component

Adopt the product produced by introducing Rexroth technology.

15.4 Cooling Of Hydraulic Pump Station

Force cooling: water cooling

15.5 Electric control

Control way: to control the hydraulic pump station by junction box.

Control power: Voltage: 380V, frequency: 50Hz, coil control power of the electromagnetic valve is DC 24V

16.Electric system

Electric system of host machine applies to operate and control each individual equipment of large diameter SSAW pipe production line, belongs to non-standard electric control system, control from uncoiler till rear bridge.

Consist of PLC auto-control system, DC speed governor, AC speed governor and digitalized display system, of which design and spare parts are in line with IS9001 and CCC standard

Have speed auto-balance governing, manually continuous adjustment

Equipped with automatic plate speed display system

Equipped with pipe sizing control and automatic cutting off system

Electric motor above 22KW (without speed regulating system) equips with reduction voltage starting

Input reactor is equipped for AC VF device and DC speed regulation device to lower pollution to power net side.

Profibus technology is used, Germany SIEMENS S7-300 serial PLC (CPU315—2DP) as main control, submodule at bus terminal and module at site adopts SIEMENS ET200 serial. Protection level of element at site is IP44, as for control cabinet and operation panel is IP20.

AC speed regulator is SIEMENS M440 serial VF speed regulator, DC speed regulator is

Eurotherm 590P serial.

Control function of electric control system is designed to tightly linked with unit process, individual equipment and hydraulic system, and can control as per variation.
