API cijevi proizvodne linije ERW610
Detalji o proizvodu
ERWΦ610 high-frequency welded pipe production line is the special equipment providing longitudinally welded pipe and cold formed steel for industries such as metallurgy, construction, transportation, machinery, vehicles and so on.Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method to produce the suitable round tube, rectangular pipe and openings cold-formed steel. The whole tube unit used “XZTF” molding process which is our self-developed to produce pipe.
Material of the coil: low carbon steel and low alloy steel σb≤758Mpa,σs≤621Mpa.
Strip Steel: Q195, Q215, Q235, Q345, K55, J55, X52, X65, X70.
Max. grade of steel: X70.
