Core Components and Functionality

The production line comprises several critical units, each contributing to its overall performance:

Auxiliary Machine Composition

• Single-Station Manual Uncoiler: Designed to handle steel strip coils with an inner diameter of Ф762mm and an outer diameter of Ф1800mm, this component ensures smooth material feeding. Its manual adjustment capability allows for flexibility in handling different coil sizes.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this system facilitates efficient material processing. Manual welding (excluding welding machines) ensures adaptability to specific project requirements.
• Four-Roller Delivery Machine: This unit maintains a steady supply of raw materials to the forming machine. Its gantry frame structure and gear split axle box design enhance stability and precision during operation.

The welded gas pipe produced by this system benefits from the auxiliary machines’ ability to handle high-speed operations while maintaining dimensional accuracy. This is crucial for applications where gas transmission requires leak-proof, durable piping.

Main Machine Composition

• Forming and Sizing Units: The system employs a seven-roller leveling mechanism, followed by a forming process with seven flat and eight vertical rollers. This configuration ensures uniform shaping of the steel strip into a cylindrical pipe.
• Extrusion and Cooling Systems: The extrusion rollers (Ф70mm, 40Cr material) and cooling water tank work in tandem to eliminate residual stresses and improve the pipe’s structural integrity. The cooling process is critical for preventing deformation during high-speed production.
• Computer Flying Saw: This advanced unit enables precise cutting of pipes to specified lengths (4–8m). Its AC motor (55KW) and DC drive system (22KW) ensure high-speed, accurate operation, reducing material waste and downtime.

The integration of these components reflects the production line’s focus on efficiency and precision. For example, the steel pipe line produced by this system is designed to withstand high-pressure environments, as emphasized by NIST’s research on material durability and manufacturing standards (NIST).

Applications and Industry Relevance

The Welded Pipe Production Line is widely applicable in sectors requiring reliable piping solutions:

• Oil and Gas: The pipes are ideal for transporting crude oil and natural gas, where their high strength and corrosion resistance are critical. NIST’s work on material testing and standards ensures that such pipes meet global safety requirements (NIST).
• Construction: The production line’s ability to create pipes with precise dimensions makes it suitable for infrastructure projects, including water supply systems and structural frameworks.
• Mechanical Engineering: The system’s high-speed operation and accuracy cater to industries requiring mass-produced, high-quality piping for machinery and equipment.

The adaptability of the production line to different materials (Q195–Q345) further enhances its appeal. For instance, the linepipe can be customized for specific applications, such as high-temperature environments or aggressive chemical exposure, as noted in technical guidelines from the American Society of Mechanical Engineers (ASME).
