How to make a distinction between various galvanized pipes in the actual purchase

Today, galvanized steel pipe has entered into millions of household and even become integral part of the normal production activities and living life. However, as a layman, it is believed that the vast majority of people even know little about the pipe and sometimes are even wrong about the pipes in default of professional knowledge of the products. For steel pipe users, it is very necessary to be able to make a distinction between various galvanized pipes correctly in the actual purchase. Here, we will come to a basic knowledge of galvanized pipe, and will learn how to distinguish between various galvanized pipes.

Technically speaking, galvanized steel pipe is a steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. It is also sometimes called galvanized iron pipe. In general, from the perspective of the shape of the steel pipe, round steel pipe and square pipe are the two most common kinds of pipes. In this regard, it is very easy for people to make a distinction according the specific shapes of pipes. Nevertheless, it seems a little difficult to distinguish between the hot dipped galvanized steel pipe and the electro-galvanized steel pipe. Because these two kinds of pipes are almost the same from their shapes, and rather, the essence of the difference is their distinct processing methods.

As a rule, with different processing technology, there will be different product costs. That can be clearly reflected in the different pipe pricing of the two kinds of pipes. Due to the high costs, hot dipped galvanized steel pipe price is more expensive than that of the electro-galvanized steel pipe. On the other hand, hot dipped galvanized steel pipe has a wider range of applications than the electro-galvanized steel pipe. Nowadays, the electro-galvanized steel pipe has been out of the steel market because of national ban on the actual purposes.

Furthermore, from a professional point of view, there is a significant difference between the two pipes from the appearance. Two different processing methods will not only affect the specific application in the practical use, but also will cause distinct steel pipe appearances. As almost all the steel pipe manufacturers know, hot dipped galvanized steel pipe has a thicker zinc layer than the electro-galvanized pipe. As long as we have a careful look, it is easy to make a distinction between these two kinds of pipes.
