Precision ERW Pipe Mill Production Line 16-50mm Diameter

The HG50 High-Frequency Welded Pipe Mill Line is designed to produce welded pipes of Ф16～50mm in diameter with wall thickness of 1.0～3.0mm, including square, rectangular, and deformed pipes of corresponding sizes. Utilizing advanced roll pass design, this production line manufactures welded steel pipes with superior machining quality and high precision assembly.

• Enhanced operational and production performance
• Improved operational environment and safety
• Increased product stability
• Higher productivity
• Reduced roll costs

The HG50 production line employs a double-radius hole design to ensure high efficiency while maintaining cost-effectiveness.
