ERW273 H.F. Straight Welded Pipe Production Line

Short Description:

ERW273 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 114mm-273mm in OD and 3.0mm-10.0mm in wall thickness, as well as corresponding square and rectangular pipe.

Products: architectural structure tubes, low-pressure liquid tubes, coal transmission belt tubes, drive shaft tubes, guardrail tubes, tower footing tubes, automobile beam steel tube and other products.

Equipment advantages：

√ ZTF forming process save roller up to 60%

√ With direct square forming technology, one set of roller can produce all pipe sizes

√ Electric control and automatic adjustment, high precision,high roller change speed

Forming process

Round pipe	Cold roll forming process	Good roller design
Round pipe	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
