We have known three types of galvanized pipes, cold galvanized pipes, cold galvanized steel pipes, hot-dip galvanized steel pipes. The stable performance and reasonable price of the hot-dip galvanized steel pipe are widely used in the pipeline today. It is widely used in our modern production and life, which brings great convenience to our life.
Cold galvanized pipe is galvanized, the amount of zinc is very small only 10-50g/m2, its corrosion resistance and hot-dip galvanized pipe is too much difference, the regular hot-dip galvanizing tube manufacturers do not use galvanizing, only those old small enterprises, small scale factory will use galvanizing, the price is very cheap.
Cold galvanized steel pipe, zinc layer and steel tube base layer, thin layer, thin layer of zinc, simple attachment on the steel tube surface is very easy to fall off, so the corrosion resistance is very poor, it is forbidden to use in the building housing.
The hot-dip galvanized steel pipe is made by the latest hot-dip galvanizing process. The steel pipe is chemically reacted with the molten zinc liquid to form a tightly structured zinc iron alloy layer, which is integrated with the pure zinc layer and the steel tube matrix, so the corrosion resistance is very strong.
The price and quality of the product have always been the key to measure the quality of the product. The product quality of the galvanized pipe is too low and the product is too low. The high price of the product may be the production of the big brand, which must be doped with the brand effect, so the galvanizing tube is chosen to see the price and the galvanized pipe manufacturer is good at the word of mouth. Purchase.
