Product Overview
The F200x200 high precision high frequency welded pipe production line is designed to produce square pipes ranging from 70x70-200x200mm with thickness from 4.0-12mm. This production line incorporates innovative design elements from domestic and international equipment, featuring full PC/computer control for advanced technology, convenient operation, and maintenance.
Key Features
- Rapid roller adjustment system minimizes changeover time between product specifications
- Combined mold system allows production of different tube specifications with adjustments rather than full roller changes (90% roller savings)
- Motorized adjustments reduce tool wear and equipment damage during roll changes
- Composite roll structure changes contact from line to point, reducing wear and extending roll life
