Comprehensive Machine Composition

Auxiliary Machines

• Single-Station Manual Uncoiler: Designed for flexibility, this unit accommodates steel strip coils with an inner diameter of Ф762mm, outer diameter of Ф1800mm, and a belt width of 280mm. Its manual operation allows for adjustments to material dimensions, ensuring compatibility with diverse production needs.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this system supports manual welding (excluding automated welding machines). It ensures precise edge alignment and secure joints, critical for maintaining pipe integrity.
• Four-Roller Delivery Machine: This machine maintains a steady supply of raw materials to the forming unit. Its gantry frame structure, combined with upper and lower roller transmission, ensures smooth material flow. Technical parameters include a feeding roller diameter of Ф170mm and a maximum speed of 140m/min.
• Cage Looper: Designed to store raw materials, this component ensures uninterrupted production by feeding the forming machine with consistent material supply. Its adjustable frame accommodates varying steel strip widths.

Main Machines

• Forming and Sizing Unit: The core of the production line, this unit features a seven-roller leveling system, seven flat and eight vertical forming rollers, and six flat and six vertical sizing rollers. The vertical roller shaft (Ф60mm) and horizontal shaft (Ф100mm) are made of 40Cr steel, treated for enhanced durability.
• Extrusion and Scraping System: The extrusion roller (Ф70mm) is constructed from 40Cr steel, ensuring uniform pressure distribution during pipe shaping. A scraping mechanism removes excess material, improving surface finish.
• Computer Flying Saw Machine: This advanced system includes a bed, gear rack, saw car, and precision sensors. It can cut pipes up to 8m in length with an accuracy of ±3mm. Key components include a 55KW AC saw motor and a 22KW DC drive motor, with a maximum cutting speed of 80m/min.
• Straightening Machine: Featuring a four-column frame, this machine eliminates residual stress and bending in the welded pipes. It employs upper (Ф220×400mm) and lower (Ф200×240mm) rollers made of GCr15 steel, operating at 100m/min for pipes with diameters of φ60–φ89mm.

Applications and Industry Relevance

The Welded Pipe Production Line is ideal for industries requiring high-strength, corrosion-resistant steel pipes. Key applications include:

• Oil and Gas Sector: For transporting crude oil and natural gas through pipelines.
• Construction Industry: As structural supports and scaffolding materials.
• Automotive Manufacturing: For exhaust systems and chassis components.
• Water Supply Systems: In municipal and industrial water distribution networks.

According to the National Institute of Standards and Technology (NIST), precision in manufacturing processes is critical for ensuring material integrity and operational safety. The production line's adherence to strict dimensional tolerances aligns with NIST's standards for industrial equipment, as highlighted in their research on manufacturing precision.
