Core Components and Functional Units

The steel pipe line is composed of multiple auxiliary and main machine units, each designed to ensure seamless operation and precision. Below is a breakdown of its key components:

1. Auxiliary Machine Composition

• Single-Station Manual Uncoiler: This unit features a manual expansion and contraction mechanism, capable of handling steel strip coils with an inner diameter of Ф762mm, outer diameter of Ф1800mm, and belt width of 280mm. It weighs 5 tons and ensures smooth material feeding.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this system allows for manual welding (excluding welding machines). It ensures precise edge alignment and robust seam welding.
• Four-Roller Delivery Machine: This component maintains a continuous supply of raw materials to the forming machine. It includes a gantry frame, upper and lower roller transmission, and a gear split axle box with vertical and horizontal pressing rollers.

2. Main Machine Composition

• Forming and Sizing System: The main machine features a seven-roller leveling unit, seven flat and eight vertical forming rollers, and six flat and six vertical sizing rollers. This configuration ensures precise shaping and dimensional accuracy.
• Extrusion and Cooling System: The extrusion roller shaft (φ70mm, 40Cr material) and cooling water tank work in tandem to eliminate residual stresses and enhance pipe quality.
• Computer Flying Saw Machine: This advanced unit includes a bed, gears, rack box, and a high-speed saw car. It can cut pipes up to φ89mm with a maximum speed of 80m/min and a sawing accuracy of ±3mm.

3. Straightening Machine

The straightening machine employs a four-column frame structure with four upper rollers and two lower rollers. The lower roller is active, while the upper rollers are manually pressed using a worm gear mechanism. This system effectively eliminates stress and bending after welding, ensuring straight, high-quality pipes.

Applications and Industry Relevance

The welded pipe production line is widely used in industries requiring line pipe steel and steel pipe line solutions. Its applications include:

• Gas and Oil Transmission: The pipes are ideal for high-pressure gas and oil pipelines due to their strength and durability.
• Industrial Piping: Used in manufacturing plants for coolant, hydraulic, and compressed air systems.
• Construction: Suitable for structural frameworks and support systems in infrastructure projects.

According to the National Institute of Standards and Technology (NIST), advanced manufacturing systems like this production line play a critical role in improving industrial efficiency and product consistency. NIST emphasizes the importance of precision engineering in reducing material waste and enhancing operational safety, which aligns with the capabilities of this welded pipe system.
