The main classification of galvanized steel pipe in details

Steel pipes are widely used in our daily life and have a good effect in all fields. Different areas require different materials which also affect the steel pipe material selection and processing procedure. For example, galvanized steel pipe is widely used nowadays and also plays out superior product performance, which is very popular in steel pipe industry. However, what are the main categories of steel pipes? What are the performances of different types of steel pipes? The name of the steel tube is closely related to the use of the steel pipe, which can be divided into hot galvanizing and cold galvanizing due to the different processing methods and product performance.

The hot dipped galvanized steel pipe adopts the alloy layer of molten metal and iron, which is combined with the coating to make it have good surface quality. Because of serious of machining way, conducting pickling is also necessary after the formation of the alloy layer. By many processing procedures, the surface quality of the steel tube has been improved greatly and it also has higher adhesion which can extend its service life effectively. Its better performance of corrosion resistance makes it application scope widely especially in construction, machinery, coal mine, chemical industry as well as automobile.

Cold galvanizing steel tube, which is often called electrogalvanizing steel pipe. This kind of steel pipe has less galvanizing, so its overall use performance is not as good as hot galvanized steel pipe. Due to the different processing technology, the zinc quantity on the surface of the pipe with poor performance is easy to fall off. This kind of steel pipe is not recommended in modern building house only in some small firms with less formal application. Steel pipe price always fluctuates in the steel pipe market. In the actual purchase, there are many things to consider. First of all is to see the scale and technical strength of the steel pipe supplier. We should know whether the steel pipe supplier have the production qualification or not. Another factor is steel pipe size. As you know different kinds of performance require different pipe specifications. When purchasing pipes, we should make a comparison among different steel pipe manufacturers.

It is necessary to understand the basic knowledge to distinguish the various performances and quality of the steel pipe and learning related pipe knowledge in advance is very important. Making a comprehensive consideration as well as a good price planning can help us choose the suitable products.
