Comprehensive understanding of galvanized steel pipe

Galvanized steel pipe is one of the most commonly used steel pipes and has a very good effect in various fields. This kind of galvanized steel pipe goes through a quite complex processing procedure and has advanced processing technology, so the pipe quality is guaranteed. This type of steel pipe meets the requirements of different industries. However, do you master some basic knowledge about this kind of steel pipe? The application effect of galvanized square tube is better. According to the application classification, the pipe effect will be affected by its property as well as adopted processing technology. There are two main categories, one is hot dipped galvanized steel pipe and another is cold galvanizing pipe. Both of the technology and application effect are distinct.

For hot dipped galvanized steel pipe, it is formed by the reaction of molten metal and iron,which is characterized by the formation of an alloy layer that is relatively effective. Generally speaking, this kind of steel tube needs a pickling process and the surface need to be removed materials such as iron oxide, then ammonia chloride aqueous is necessary. The cleaning process can make the surface layer of the round steel pipe more evenly and the adhesion performance will be enhanced. All these procedures can make the service life of the product extended. From the performance view, the overall performance of this kind of steel tube is better and the corrosion resistance is also strong. However, the cold galvanized steel pipe is usually processed by electroplating and the zinc quantity is less, so the overall corrosion resistance is worse than that of hot dipped galvanized steel pipe. Nowadays, the quantity of cold galvanized steel pipe is less and less and pre galvanized steel pipe is more popular in the steel pipe market.

How to distinguish these two kinds of steel pipe? In fact, the distinguish method between hot and cold galvanized steel pipe is simple and can be directly determined through its material and processing parameters. Speaking of application, hot dipped galvanized steel pipe is more common and we should pay more attention to the daily inspection so that we can find problems timely. Steel pipe manufacturers should master more professional knowledge about steel pipes to provide customers with more sophisticated advice when they choosing steel pipes. As a customer, we also need to learn how to check the product parameters. Any doubts about galvanized steel pipe?
