Automatic Steel Pipe Galvanizing Line
GONGDA is one of the famous plating equipment suppliers in China. Our automatic steel pipe galvanizing line features high automation degree, PLC control system, and fluted disc galvanizing method. Variable frequency motor is used for controlling the galvanizing time. Comparing with other hot-dip galvanizing solutions, this galvanizing equipment is more flexible in terms of processing time. The steel pipe with a 1/2"~6"drift diameter can be automatically dipped into the galvanizing kettle. Specifically,two or four pipes with 1/2"~2" diameters could be galvanized by our automatic steel pipe galvanizing line each time, while for those that are 2"~6" in diameter can be processed one piece a time. The inner wall of the pipe is blown by steam, while the outside will be blown by compressed air.
