This high-frequency welded tube mill line produces round tubes with diameters of 25.4-114mm and wall thicknesses of 0.8-4.0mm. Utilizing roll forming technology, it processes steel strip into various shapes. The system employs high frequency induction heating to create section material of diverse diameters and sizes by welding seams into closed shapes. Advanced aperture technology, PLC automatic control, and British Eurasia digital speed-regulating units ensure reliable operation and easy maintenance.
Equipment is classified by application: Industrial stainless steel pipe making machines and decorative stainless steel pipe making machines.
- Decoiler: Holds and feeds steel strip into the forming section
- Forming section: Utilizes scroll welded pipe dies
- Welder: Performs the welding operation
- Grinding section: Processes weld seams
- Straightening and sizing section: Fine-tunes pipe diameter
- Cutting section: Hydraulic or grinding wheel cutting
- Length fixing: Automated material definition
Our equipment is known for durability, high precision, full automation, ease of operation, continuous production capability, high efficiency, minimal material waste, excellent finished product rate, and low production costs.
- Improper welding torch position
- Misaligned welding torch
- Excessive current causing melting
- Insufficient current for proper welding
- Lack of argon causing unfocused welding
- Contamination (water or oil) on molds or steel
A complete setup requires the pipe making machine, welder, molds/dies/rollers, polishing machines (round or square), polishing materials, and steel strip.
