Decriptions
“NEW GARDEN” Brand hot DIP galvanized pipe, the basic steel pipe is high-frequency welded pipe, and then the pipes will be pre-processing as De-greasing, Rinsing, Pickling, Washing ,Dipping Fluxing, Hot Air Drying etc before dipping galvanized. The inner and outer surfaces of the pipes are bright and uniform in color, and the welds are evenly formed into a linear shape. Each pipe is detected by eddy current. The hot-dip galvanizing used in the steel pipe is No. 0 zinc, which has strong corrosion resistance, and the inside and outside of the pipe have undergone special anti-corrosion treatment.
production process
Material Inspection(Steel Pipe) --- De-greasing --- Rinsing --- Pickling --- Washing --- Dipping Fluxing --- Hot Air Drying Inside and Outside Hot-dipped Galvanizing Blow --- Cooling --- Passivation and Rising --- Unloading --- Inspection and Trimming --- Type Identification Packaging and Storing and Transportation
