Technical flow

Raw material (with steel strip coil) → decoiler → shear and butt-welder → strip sccumulator → passively leveling → forming machine → high frequency welding → remove the burrs outside → spraying & cooling → sizing machine → straightening → fixed length cutting → run out table → finished tube

Forming process

Round pipe

Cold roll forming process

Good roller design

Square & rectangular pipe

General round-to-square process

Stable forming process

Round to square with turkshead
