Spiral Duct Specific measures:

Spiral Duct Install the smoke baffle plate on the trolley inside the steel tube and place it at the plasma gun cutting point of about 500mm. After the steel tube is cut off, it will stay for a while to fully absorb the smoke.Note Spiral Duct that the smoke baffle should be accurately positioned after cutting.In addition, in order to make the trolley supporting the dust baffle coincide with the rotation of the steel tube, the wheel Angle of the trolley must be consistent with the Angle of the inner roller.This Spiral Duct method can be used for plasma cutting of large diameter spiral welded pipe with a diameter of about 800mm.For diameter less than 800mm, Spiral Duct pipe diameter small smoke can not be from the direction of the pipe, do not install internal baffle.However, there Spiral Duct must be an external baffle to keep out cold air at the inlet of the smoke suction of the molding machine.The Spiral Duct above is all about the cutting method of spiral steel pipe. If Spiral Duct you have any questions, please Spiral Duct contact our customer service directly. We will serve you wholeheartedly.
