Introduction of two main specifications of welded steel pipe

When it comes to steel pipe, we may think that straight seam welded steel pipe is more of a kind of popular pipe than any other pipe types. Besides, it is also the most common pipe in the steel pipe market. Why would we say that? As it is very common in the general type so we can say that it is a very common steel pipe. In addition, it is widely used in all walks of life especially in the construction industry and we can see it everywhere. Its special performance lies on large application scope, so it is a special type of steel tube. Today, we will introduce the most basic steel pipe specifications of welded steel pipes.

Among the international prevailing standard, there is a basic classification. Actually, the classification is based on the shape of the steel tube that is from general to specific. That is respectively divided into round steel pipe and square steel tube. For welded steel pipe specifications, round steel pipe is very common steel pipe no matter in our daily life or in production industry. This classification standard also means that there exists certain relationship between pipe term and pipe application. Speaking of square steel pipe, it is popular with projects that has high requirements of stability.

Apart from shape classification standard, there will be more detailed division. International standard is divided according to the diameter size of the pipeline. For round steel pipe, it is divided for internal diameter while for square steel pipe, it is determined according to the width of a transverse walls. The difference between them is that the determination of the caliber is different. Of course, in our actual life, the two kinds of steel tube will have a more detailed classification such as a plenty of application for mechanical parts. This kind of specification is described in accordance with international standards.

The price fluctuation of welded steel pipe has influence on the pipeline of two kinds of specifications. Under the same conditions, the price of square steel pipe is higher than that of round steel pipe. This is because square steel tubes make up large amount of materials compared with economical round steel pipe. In addition, the smaller the size of the two types of steel pipes, the lower the price is. Steel pipe manufacturers should know more details when producing these two main specifications of welded steel pipe.
