The spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.) has been widely used by people, and it is also widely used in oil and natural gas transmission pipelines. Then, in order to better ensure the spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.), the spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.) has special requirements for steel strips during its production process. , which can be used to improve the weldability of steel pipes; therefore, when reducing the carbon content, reducing the sulfur content in the steel is beneficial to improve the ductility and crack inhibition of the steel pipe. It also reduces the mixing of sulfide inclusions and improves the crack resistance of the steel. At the same time, it can reduce the sulfur content and improve the quality of the steel strip parts.

The production process of the spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.):

1. Inspection of raw materials: strip coil, welding wire, welding machine.

2. The strip is preformed after straightening, shearing, planing and rolling.

3. The spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.) controls the welding gap and adjusts the forming diameter of the light pipe.

4. Automatic double-sided submerged arc welding machine welding steel pipe forming

5. Measure the diameter of the steel pipe and check the weld manually.

6. Completed the air plasma cutting of the spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.).

7. Both ends of the spiral steel pipe are flat and beveled.

8. Check the spiral steel pipes produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.) in accordance with the implementation standards.

9. The spiral steel pipe produced by Hebei Spiral Steel Pipe Factory (Zhongyuan Pipeline Manufacturing Co., Ltd.) will be delivered to the warehouse after passing the inspection.
