Frequently Asked Questions
The system is optimized for low carbon steel (yield strength δs≤275Mpa, tensile strength δb≤500Mpa) in both cold-rolled and hot-rolled coil forms.
The spiral accumulator allows the forming line to continue running while the operator switches coils at the uncoiler, eliminating downtime and maximizing efficiency.
The line is versatile and can produce round, square, or rectangular pipes, though the specific rollers must be configured for the desired shape during setup.
MOSFET inverters provide higher efficiency (η≥85%) and more stable power delivery compared to traditional transformers, resulting in stronger and cleaner weld seams.
Our rollers are made from Cr12 and H13 steel with high hardness (50-60 HRC), significantly reducing wear and the frequency of replacements.
Thanks to the CNC flying friction saw and speed testing rollers, the length tolerance is maintained within 0-6mm for a standard 6.0m pipe.
