Product Description
ERW508 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 produce the suitable round tube.
Material of the coil: low carbon steel and low alloy steel
(σb≤827Mpa,σs≤690Mpa.)
Strip Steel: Q235, Q345, 20＃, X42, X56, X70, X80.
Our advantage
"FF" Forming Way Advantage
It can save 60% expenses on rollers;
One set of roller can be used to produce all round pipe between Φ168 and Φ406 in the break down section. And roller in the breakdown section needn’t to be changed;
It can reduce product period;
It is easier to restore and adjust roller;
Adjusting and maintaining easier;
All the roller adjusting by servo motor.
Welding Section
Welding section: guide roll stand, squeeze roll stand, HF welder, Inside and outside bead scraping device, polishing roll stand, UT, Annealing, water and air cooling.
What is the delivery time for this machine?
It is need about 10months.
