ERW square tube mill & pipe making machine
The high-frequency straight seam square tube welded pipe production line includes two processes: direct square forming and Turkish head round-to-square conversion, producing square tubes and rectangular tubes.
ZTZG has independently developed, designed, and manufactured a square tube production line for large-diameter and small-diameter square tubes, producing different specifications. The entire line is electrically adjustable online and does not require mold replacement.
