[0002] Spiral air ducts are mainly used to connect the air circulation between two places and play a role in ventilation. In the market, spiral air ducts are generally divided into three categories according to the material: galvanized spiral air ducts, stainless steel spiral air ducts, and composite spiral air ducts. After the spiral air ducts are welded, most users need to use pickling and passivation paste to clean their welds.
