Key Components and Functionality

The production line consists of multiple specialized units, each designed to optimize efficiency and quality:

1. Auxiliary Machine Composition

• Single-station manual uncoiler: Adapts to steel strip coils with inner diameter Ф762mm and outer diameter Ф1800mm, ensuring smooth material feeding.
• Shearing and welding unit: Features hydraulic cutting and pneumatic pressing for precise welding, excluding the welding machine itself.
• Four-roller delivery machine: Maintains raw material supply with a gantry frame structure, equipped with gear split axle boxes and vertical/horizontal pressing rollers.

2. Main Machine Composition

• Passive seven-roller leveling: Ensures uniform steel strip flatness before forming.
• Forming and sizing units: Includes 7 flat and 8 vertical rollers for shaping, followed by 6 flat and 6 vertical rollers for sizing.
• Extrusion and cooling system: Applies pressure to finalize pipe shape while cooling to maintain structural integrity.

3. Computer Flying Saw Machine

Equipped with a 900mm saw blade, this unit achieves ±3mm accuracy in cutting pipes to fixed lengths of 4–8m. Its 55KW AC motor and 22KW DC drive ensure high-speed operation (up to 80m/min).

4. Straightening Machine

Eliminates post-welding stress and bending through a four-column frame structure with 220×400mm upper rollers and 200×240mm lower rollers. The 30KW motor enables a straightening speed of 100m/min.

Applications and Industry Relevance

The Welded Pipe Production Line is widely used in:

• Construction: For structural steel pipes in buildings and bridges.
• Energy Sector: In gas and oil pipelines, where welded gas pipe ensures leak-proof performance.
• Manufacturing: For producing linepipe and other industrial components.

According to NIST, "precision in manufacturing processes is critical for ensuring the reliability of industrial equipment" (NIST.gov). The production line's adherence to strict tolerances aligns with these principles.
