Galvanized Steel Pipe
Galvanized pipe, also known as galvanized steel pipe, is divided into two types: hot-dip galvanized and electro-galvanized. Hot-dip galvanized galvanized layer is thick, and has the advantages of uniform coating, strong adhesion and long service life. The cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
 
 
 
Production Process:
Black parts inspection→hanging material→degreasing→rinsing→pickling→cleaning→dipping flux→hot air drying→hot-dip galvanizing→internal and external blowing→cooling→passivation and rinsing→unloading→inspection, trimming→typing and marking →Package storage and transportation.
 
Galvanized strip→uncoiling→stretching→rolling pipe→welding→scratching→passivation and rinsing→galvanizing→setting→typing and marking→cutting→packing→drying→weighing.
