Ф600~2700x16 Front swing spiral welded pipe production line
I. Overview:
Spiral welded pipe unit adopts the intermittent production form of front swing, which is a complete set of spiral welded pipe production line equipment with the integration of mechanical, electrical automation control and hydraulic control. The equipment in the host area completes the production of steel coil to spiral steel pipe through the processes of uncoiling, leveling, milling, molding, welding, etc. The equipment in the finishing area completes the processing and inspection processes such as flat head chamfering of steel pipe, hydrostatic test, X-ray flaw detection, ultrasonic flaw detection, and diameter expansion, etc. The machine is used for the production of spiral seam welded pipe.
Spiral steel pipe machine is used to manufacture spiral seam welded pipe, can use the same width of the strip steel production of different diameters of steel pipe, with different width of the strip steel production of the same diameter of steel pipe.
Spiral welded pipe is widely used in different industries and different occasions, such as low pressure fluid transportation pipe, city gas pipeline, electric power and heat pipeline, urban construction pile pipe, industrial structure pipe, national large-scale oil and gas transportation pipeline, etc., in order to meet the needs of different industries and markets.

III. Φ600-2700mm process flow
1. Main Machine Process Flowchart:
Raw material steel coil → Uncoiling (head removal) → Pinch leveling → Electric centering → Cutting and butt welding → Electric centering → Edge milling → Manual centering → Feeding → Guide plate → Forming → Inner and outer welding → Flying cut → Pipe output
2. Process description:
The crown block lifts the steel coil to the center of the uncoiler cone head; Under the action of the oil cylinder, the double cone head rises and falls, the center of the cone head is aligned with the center of the inner diameter of the steel coil, and the left and right oil cylinders act to make the cone head clamp and press down the steel coil. Then, the idler motor is started to drive the idler to rotate and drive the steel coil to rotate. At the same time, the head disassembling machine swings the oil cylinder to make the shovel head abut against the plate head of the steel coil (the steel coil wrapping tape is cut manually), and the strip head is led out (the uncoiler can realize transverse centering according to the different plate widths).
The head of strip steel is fed into the pinch machine by the swing roller of the head stripper. After the upper roller of the pinch machine is pressed down by the hydraulic cylinder, the head of strip steel is fed into the five-roller leveler for leveling under the rotation of the pinch roller.
After the tail of the last coil of strip steel is cut completely, it stops at the butt welding position, and after the head of the last coil of strip steel is cut completely, it is sent to the butt welding position by a five-roll leveler; After cutting, the head and tail of strip steel are pressed on the workbench of butt welding device through vertical roll alignment, and then welded by automatic submerged arc welding machine. (Shutdown of the above processes is completed)
The strip steel enters the forming machine under the control of guide plates and vertical rollers. The forming machine adopts three-roll all-inclusive auxiliary universal forming with adjustable external control rollers to bend the continuously fed strip steel into a spiral steel tube cylinder. At the same time, internal welding is carried out at the bite point of the forming machine, and external welding is carried out at a half pitch or a half pitch position. When the output of the welded steel tube reaches a fixed length, the fixed-length control system sends a signal to control the flying cutter to cut the steel tube. The steel pipe cut to length is sent to the steel pipe rotary device by the pipe transport trolley, and then sent to the conveying roller table in the finishing area by the steel pipe rotary device, and the steel pipe enters the finishing area for other processes.
