Description

Technical Field

[0001] This utility model relates to the field of automatic adjustment technology for spiral welded pipes, and in particular to an automatic adjustment device for spiral welded pipe forming rollers. Background Technology

[0002] Spiral welded pipe is a metal pipe made from hot-rolled steel strip through spiral coiling and welding. Its characteristics are as follows: **Process Advantages:** Utilizing a continuous spiral forming process, it can produce large-diameter (typically Φ219~Φ3000mm) and ultra-long fixed-length pipes. Different specifications can be produced from the same unit by adjusting the forming angle. **Structural Characteristics:** The spiral weld seam results in a more uniform stress distribution within the pipe body, offering superior pressure resistance and deformation resistance compared to straight-seam welded pipes, making it suitable for high-pressure transportation applications. **Application Areas:** Primarily used in long-distance oil / natural gas pipelines, municipal drainage, bridge foundations, and other projects, especially suitable for pipeline laying in complex terrain. **Technological Development:** Modern spiral welded pipes employ online ultrasonic testing and automatic submerged arc welding technologies, achieving weld quality that meets API 5L / GB / T 9711 standards. Its low production cost and strong adaptability make it a crucial component in energy infrastructure.

[0003] In the production process of spiral welded pipes, several abutting rollers are used to achieve ring forming. However, the traditional method involves manually adjusting the abutting rollers, resulting in low intelligence and an inability to automatically adjust and control the rollers according to the diameter of different pipes, which is inconvenient to use.
