Components of Welded Pipe Unit

The welded pipe unit mainly consists of the following parts:

1. Pipe delivery device. Feeds the steel pipe from the storage rack into the welding work area, providing continuous steel pipe raw materials for welding operations.

2. Positioning device. Accurately positions the two ends of the steel pipe to ensure welding quality and operational efficiency.

3. Transfer device. Aligns and tightens both ends of the steel pipe to achieve precise axial alignment, providing the correct welding position for the resistance welding machine.

4. Resistance welding pipe machine. Using high-strength and dense resistance coils, high temperatures are generated through high current conduction, melting both ends of the steel pipe, and welding to form a long pipe.

5. Release mechanism. Smoothly releases the finished long tube from the workbench to make room for the next cycle of operations.

6. Intermittent pipe feeding. By using a travel switch to control the pipe feeding device, intermittent and continuous pipe feeding can be carried out according to the working rhythm of the resistance welding machine, ensuring operational efficiency.

7. Automation control. Usually, PLC or industrial control machines are used to set, monitor, and control process parameters, reducing the difficulty of manual operation.

8. Safety protection. Equipped with electromagnetic shielding doors, ventilation devices, anti-splash devices, etc., to ensure the safety of operators.

9. The cost is relatively high. The welded pipe unit contains a large amount of mechanical, electrical, and automation technology, and other equipment with high value, which also requires high space, power, and maintenance requirements.

In summary, the welded pipe unit mainly uses resistance welding methods and precise mechanical and automatic control technology to achieve continuous feeding, positioning, rotation, welding, and pipe laying functions of long steel pipes. This can greatly improve the production efficiency and quality of steel pipe welding. The unit has a high cost and is mainly used in large-scale steel pipe processing production lines.
