Key Features and Advantages

1. Advanced Forming Technology

The production line utilizes high-frequency straight seam welding technology, ensuring strong and uniform welds. The system includes a seven-roller leveling unit and a seven-flat and eight-vertical forming system, which guarantees precise shaping of the steel strip into the desired pipe dimensions. The six-flat and six-vertical sizing mechanism further enhances the accuracy of the final product.

2. Efficient and Reliable Auxiliary Machines

• Single-Station Manual Uncoiler: Designed to handle steel strip coils with an inner diameter of Ф762mm and an outer diameter of Ф1800mm, this uncoiler ensures smooth material feeding.
• Shearing and Welding Unit: Equipped with hydraulic cutting and pneumatic pressing platforms, this unit allows for precise manual welding (excluding the welding machine).
• Four-Roller Delivery Machine: This machine maintains a continuous supply of raw materials to the forming and sizing unit, featuring a gantry frame and gear split axle box for stability.

3. Precision Cutting and Straightening

The computer-controlled flying saw machine ensures accurate cutting of steel pipes to the required lengths, with a maximum sawing speed of 80m/min and a blade size of Ф900mm. The straightening machine eliminates residual stress and bending, using a four-column frame structure and GCr15 material rollers to achieve a straightening speed of 100m/min.

Applications

This production line is widely used in industries requiring high-strength steel pipes, including:

• Construction: For structural frameworks, scaffolding, and reinforcement bars.
• Oil and Gas: In pipelines for transporting crude oil, natural gas, and other fluids.
• Infrastructure: For water supply systems, drainage networks, and underground utilities.
• Manufacturing: As components in machinery, vehicles, and industrial equipment.
