Forming process
Round pipe | Cold roll forming process | Good roller design |
ZTF forming process | Save roller up to 60% and realize electric control adjustment |
|
Square & rectangular pipe |
General round-to-square process | Stable forming process |
Round to square with turkshead | Good pipe quality, reach same wall thickness with round pipe | |
Process of directly forming into square shape | One set of roller can produce all pipe sizes & realize electric control and automatic adjustment |
