Full Automatic 16mm ERW Pipe Mill for 80x80-200x200mm Square Tubes

The F200x200 high precision high frequency welded pipe production line produces square pipes ranging from 80x80-200x200mm with thickness from 3-16mm. This production line incorporates innovative design elements from domestic and international equipment, featuring full PC/computer control for advanced technology, convenient operation and maintenance, meeting international standards.

• Rapid roller adjustment capability significantly reduces product changeover time, improving efficiency and reducing production costs
• Utilizes combined molds allowing production of different tube specifications through adjustment rather than replacement, achieving over 90% roller savings
• Motorized adjustments minimize tool input and equipment damage during roll changes, extending equipment service life
• Composite roll structure changes contact from line to point, reducing wear and extending roll life
