High Frequency Straight Seam Welded Pipe Production Line - BzZhou Xinghua | Precision, Efficiency, Durability

The High Frequency Straight Seam Welded Pipe Production Line is a cutting-edge solution designed for manufacturing electric welded steel pipes with precise dimensions and high-quality standards. This production line is specifically engineered to produce pipes with diameters ranging from φ76 to φ89mm and wall thicknesses between 2.0–5.0mm. It is a critical asset for industries requiring durable and reliable steel pipes for applications such as gas transmission, structural support, and industrial machinery.

Product Overview

The production line is a comprehensive system that integrates advanced machinery to ensure efficiency, precision, and durability. It is tailored for materials such as Q195–Q345 steel strips, which are known for their strength and versatility. The system's ability to handle a wide range of steel strip widths (238–279mm) and thicknesses (2.0–5.0mm) makes it adaptable to various industrial needs. The final product, steel pipes, can be customized to lengths between 4–8 meters, with a length accuracy of 0–6mm.

One of the standout features of this production line is its high forming speed, which operates at 60–80m/min. This ensures high throughput, making it ideal for large-scale manufacturing. The system's design also emphasizes precision, with components like the computer flying saw machine capable of cutting pipes to exact specifications with an accuracy of ±3mm.

Auxiliary Machine Composition

The production line includes several auxiliary machines that ensure smooth and efficient operation:

• Single-station manual uncoiler: This machine handles steel strip coils with an inner diameter of Ф762mm and outer diameter of Ф1800mm, with a belt width of 280mm and weight capacity of 5 tons.
• Shearing and welding system: Equipped with hydraulic cutting and pneumatic pressing platforms, this system allows for manual welding (excluding welding machines).
• Four-roller delivery machine: Designed to store raw materials and feed the welded steel strip into the storage bin, this machine features a gantry frame, upper and lower roller transmission, and a gear split axle box with guide vertical and horizontal pressing rollers.
• Cage looper: This component ensures continuous production by storing raw materials for the forming and sizing machine, with adjustable frames to accommodate different steel strip widths.

Main Machine Composition

The core of the production line consists of the main machine, which includes the following components:

• Technical Parameters: The machine uses Q195–Q345 steel strips with thicknesses of 2.0–5.0mm. It operates at a welding pipe speed of 60–80m/min and is powered by a 250KW DC motor (Z4-280-42) and a ZLY280-10 reducer.
• Unit Arrangement: The machine features a passive seven-roller leveling system, feeding vertical rollers, forming 7 flat and 8 vertical rollers, sizing 6 flat and 6 vertical rollers, and a Turkish ear head with 8 rollers (4 single-sided).
• Roller Shafts: The horizontal shaft is Ф100mm, while the vertical roller shaft is Ф60mm, both made of 40Cr and heat-treated for durability. The extrusion roller shaft is Ф70mm, also made of 40Cr.
• Computer Flying Saw Machine: This system includes a bed, gears, rack box, saw car, and speed measurement system. It can cut pipes with diameters of Ф76–89mm and wall thicknesses of 2–5mm, with a maximum sawing frequency of 15 times/min.

Straightening Machine

The straightening machine is designed to eliminate stress and bending after welding. It features a four-column frame structure with four upper rollers and two lower rollers. The lower roller is active, while the upper rollers are passive and pressed down by a worm gear (manual). The machine operates at a speed of 100m/min, handling pipes with diameters of φ60–φ89mm and wall thicknesses of 2.0–5.0mm.
