250mm×250mm -500mm×500mm High Speed Automatic API Oil Steel Pipe
Making Machine
ERW660 high frequency longitudinal welded pipe production line /
pipe making machine / tube mill is designed to produce welded pipes
of 325mm-660mm in OD and 6mm-20mm in wall thickness, as well as
corresponding square and rectangular pipe.
Advantage:
When producing round pipe, it can utilize ZTF forming technique
When producing square & rectangular tube, it can utilize directly
square-square (DSS) technique
Products:
Architectural structure pipes, API pipes, tower footing tubes,
automobile beam steel pipe and other products.

Forming process:
ZTF forming process:Save alt least 60% roller cost with electric
control adjustment
General round-to-square process:Stable forming process
Round-to-Square with Turks head:Good pipe quality
Process of directly square-to-square(DSS):One set of roller can
produce all tubes with electric control and automatic adjustment
We can also design square tube machine depends on customer’s
requirement.
