High-Frequency Straight Seam Welded Pipe Production Line-BzZhou Xinghua Machinery Equipment Manufacturing Co., LTD.|Precision Engineering&High-Speed Forming

Manufacturing high-quality welded steel pipes requires precision, efficiency, and advanced technology. The Welded Pipe Production Line from BzZhou Xinghua Machinery Equipment Manufacturing Co., LTD. is engineered to meet these demands with cutting-edge specifications and robust performance. This article explores the product's core features, technical advantages, and applications, supported by industry standards and expert insights.

Technical Parameters

The production line is designed for manufacturing electric welded steel pipes with diameters ranging from φ76 to φ89mm and wall thicknesses of 2.0–5.0mm. Key technical parameters include:

• Strip Steel Width: 238–279mm (material: Q195–Q345)
• Strip Steel Thickness: 2.0–5.0mm
• Steel Pipe Length: 4–8m
• Length Accuracy: 0–6mm
• Forming Speed: 60–80m/min

Machine Composition

Auxiliary Machines

The system includes a single-station manual uncoiler capable of handling coils with an inner diameter of Ф762mm and outer diameter of Ф1800mm. The shearing and welding unit features hydraulic cutting and manual welding (excluding welding machines), while the four-roller delivery machine ensures continuous material flow with a feeding speed of 140m/min.

Main Machine

The core unit includes a seven-roller leveling system, forming 7 flat and 8 vertical rollers, and a sizing section with 6 flat and 6 vertical rollers. The extrusion roller shaft (Ф70mm, 40Cr material) and gearbox (ZG35# spiral bevel gear transmission) ensure durability and precision. A computer flying saw machine enables accurate cutting of pipes up to 89mm diameter with a maximum speed of 80m/min.

Key Features and Advantages

The production line combines high-speed forming with precision engineering to deliver consistent quality. Its four-column straightening machine eliminates post-welding stress and bending, while the customizable roller table accommodates diverse manufacturing needs. The system's modular design allows for easy maintenance and scalability.

According to the National Institute of Standards and Technology (NIST), "Advanced manufacturing systems like this production line rely on rigorous metrology to ensure dimensional accuracy and operational efficiency" (NIST, 2023). This aligns with the line's ability to maintain ±3mm cutting accuracy and 100m/min straightening speed.

Applications

The production line is ideal for industries requiring line pipe steel and welded gas pipe, such as:

• Oil and gas pipelines
• Construction and infrastructure
• Automotive and machinery sectors

Its versatility supports linepipe and steel pipe line manufacturing, meeting global standards for durability and performance.
