Requirements for the production process of hot-dip galvanized steel pipe

Nowadays, there are many kinds of steel pipe products available in the market. As different production industries are different, the production process of steel pipes is also different. From the current steel pipe market, it is obvious that welded steel pipe is widely used in our daily life. According to the main classification, pipe quality tops the list of customer demands, provided by specification table of galvanized steel pipe. Moreover, it can mainly divided into hot dipped galvanized steel pipe and cold galvanized steel pipe. Compared with these two kinds of steel pipe, hot dipped galvanized steel pipe is more premium both in technology and quality security. So what are process quality requirements for hot-dip galvanized steel pipe? Here is a brief introduction to the actual process of the steel pipe.

Considering the problems in foreign trade of galvanized steel pipe, the standard requirements for hot-dip galvanized steel pipe processing technology are higher. In the form of its basic production and processing technology, hot dipped galvanized steel pipe is mainly used to produce a very good layer of alloy through the reaction of molten metal and iron. In order to ensure pipe quality, we should pay more attention to the zinc coating. General speaking, in the actual production, the first step is the pickling of steel pipe, then remove iron oxide, which can ensure quality of steel pipe processing. After pickling, they should be put into the ammonium chloride aqueous solution in the sink for washing so that the zinc coating can be more uniform. If the alloy layer and coating can be better together, the corrosion resistance of steel will be more effective, while china cold galvanized steel pipe has inferior quality compared with hot dipped galvanized steel pipe.

What are the downstream industries of galvanized steel pipes? Galvanized steel pipe has more downstream industry and the effect is quite good. The quality requirements of galvanized steel pipe are still very high. In order to guarantee the uniformity of galvanized pipe specifications, the steel should be put into the copper sulfate solution for five times in a row. Secondly, we should guarantee the appearance of the steel pipe without shading and bubbles. According to the actual needs of different customers, you can directly contact with steel pipe manufacturers to safeguard the efficient application of steel tube.
