Main Features and Advantages

The welded pipe production line is engineered to deliver exceptional performance and reliability. Its key features include:

• High Precision: The system ensures length accuracy of 0–6mm, meeting strict industry standards for line pipe steel applications.
• Efficient Forming Speed: With a forming speed of 60–80m/min, the production line maximizes throughput while maintaining quality.
• Robust Construction: Components like the four-roller delivery machine and straightening machine are built with high-strength materials (e.g., GCr15, 40Cr) to withstand demanding industrial environments.
• Customizable Solutions: The system supports customized drawings for roller tables and stands, ensuring adaptability to specific production needs.

The auxiliary machine composition further enhances the production line’s versatility. For instance, the single-station manual uncoiler accommodates steel strip coils with an inner diameter of Ф762mm and an outer diameter of Ф1800mm, while the shearing and welding unit employs hydraulic cutting and pneumatic pressing for precise seam formation.

Technical Components

The main machine composition includes a passive seven-roller leveling system, forming 7 flat and 8 vertical rollers, and a 6 flat and 6 vertical sizing unit. These components work in harmony to ensure uniform pipe geometry and structural integrity. The extrusion roller shaft and horizontal shaft are designed for durability, with materials like 40Cr and 20CrMnTi ensuring resistance to wear and deformation.

The computer flying saw machine is a critical component for accurate cutting. It features a 900mm saw blade, a 55KW AC motor, and a 22KW DC driving motor, enabling efficient operation at speeds up to 80m/min. The straightening machine eliminates stress and bending through a four-column frame structure, with upper and lower rollers made of GCr15 for high hardness and precision.

Application Scenarios

This welded pipe production line is ideal for industries requiring line pipe steel and welded gas pipe solutions. Common applications include:

• Oil and Gas Pipelines: The system produces φ76–φ89mm pipes suitable for low-pressure gas and water distribution networks.
• Construction Industry: High-strength line pipe steel is used in scaffolding, structural supports, and drainage systems.
• Automotive Manufacturing: The precision and durability of the pipes make them suitable for vehicle chassis and exhaust systems.
• Industrial Equipment: The production line caters to manufacturers of machinery, HVAC systems, and hydraulic components.

The steel pipe line is particularly well-suited for projects requiring high-frequency straight seam welded pipes, which offer superior strength-to-weight ratios and corrosion resistance. Its customizable design allows for integration into existing production workflows, reducing downtime and maintenance costs.
