Technical Specifications

Key Components and Functionality

Auxiliary Machine Composition

• Single-Station Manual Uncoiler: Adapts to steel strip coils with an inner diameter of Ф762mm and outer diameter of Ф1800mm. It ensures smooth material feeding with a belt width of 280mm and a weight capacity of 5 tons.
• Shearing and Welding Unit: Features hydraulic cutting, pneumatic pressing platforms, and manual welding (excluding welding machines). This ensures precise edge preparation and secure joining of steel strips.
• Four-Roller Delivery Machine: Maintains a continuous supply of raw materials to the forming machine. It includes a gantry frame, upper/lower roller transmission, and a gear split axle box with vertical and horizontal pressing rollers. Technical parameters include a feeding roller diameter of Ф170mm and a speed of 140m/min.

Main Machine Composition

• Forming and Sizing Unit: Features a seven-roller leveling system, seven flat and eight vertical forming rollers, six flat and six vertical sizing rollers, and a Turkish ear head (8 rollers, single-sided 4 rollers). This ensures precise shaping and dimensional accuracy.
• Extrusion and Cooling System: The extrusion roller shaft (Ф70mm, 40Cr material) and cooling water tank work in tandem to enhance pipe quality and durability.
• Computer Flying Saw Machine: Equipped with a 55KW AC saw motor and a 22KW DC driving motor, this unit achieves a maximum sawing speed of 80m/min and a precision of ±3mm.
• Straightening Machine: A four-column frame structure with four upper and two lower rollers (upper roller pressed manually via a worm gear) eliminates stress and bending. It operates at 100m/min with a straightening roller diameter of φ120mm.

Applications and Industries

The φ76—φ89 High Frequency Straight Seam Welded Pipe Production Line is ideal for industries requiring high-strength, corrosion-resistant steel pipes. Key applications include:
