Method for ensuring the quality of hot-dip galvanized wire during production

Hot wire plating is made of high quality low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanizing, cooling and other processes. Insulation layer of hard insulation products, can use no. 16 ~ 18 galvanized iron wire double strand binding, binding spacing should not be greater than 400mm. However, pipes or corresponding equipment with a nominal diameter equal to or greater than 600mm should be bundled and reinforced with galvanized iron wires of no. 10 to no. 14 or packing steel belts with a spacing of 500mm.

The insulation layer of semi-rigid and soft insulation products should be bound with steel tape, no. 14 ~ 16 galvanized iron wire or adhesive tape with a width of 60mm according to the diameter of the pipe and the size of the equipment. The spacing of the binding, semi-rigid insulation products should not be greater than 300mm. For soft felt, pad should not be more than 200mm.

Hot wire atmospheric relative humidity at the same temperature, the percentage of atmospheric water vapor content and water vapor saturation content, called the relative humidity. Below a certain relative humidity, the corrosion rate of metal antirust oil is very small, but when it is higher than this relative humidity, the corrosion rate increases sharply. Direct contact with acid and alkali by human skin is prohibited. When the acid fog exceeds the targets specified by the state, timely measures shall be taken to control it; otherwise, production shall not be allowed.

Practice for safe operation of hot-dip galvanized iron wire: Remove all hindering tools and piles from work site and equipment. When pickling, the wire is slowly put into the cylinder to prevent acid from splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent the acid from splashing out and wounding people. Wear protective glasses when working. Receiving line and operation should pay attention to safety, others without consent, not on the bus operation. The wire reel should be placed lightly, stacked firmly and neatly, not more than 5 plates.
