Brief analysis of straight seam welded steel pipe

The production technology of steel pipe such as welded steel pipe was developed in earlier 19th century because of the exploitation and transportation of oil and gas and the manufacturing of boilers, ships, airplanes and so on. To date, it is an indispensable foundation material in nation-building with good performance and it has entered many aspects of our daily life. The steel tube can be divided into many types according to the production methods, surface coating characteristics, section shape and so on. Taking the production method as an example, the pipe can be split into two types: seamless steel tube and welded steel pipe. Besides, the seamless steel tube can be divided even more according to the hot rolling and cold rolling in the production process and the welding steel tube can be divided on the basis of different welding process and welding form. If the classification standard is welding form, the welded steel pipe can be divided into spiral welded pipe and straight seam welded steel pipe.

In the practical application, we can see the relationship which is inextricably between the method and application of the steel pipe as the term of steel pipe is very rigorous. By the pipe term, we can analyze the production process of the steel pipe so as to know the physical and chemical properties of such steel pipes and different properties can be used for different purposes. In the case of welded round steel pipe, it is the shape of bending the steel plate into tube then welding the straight line on the pipe surface. Because of the different welding form of the seam, the structure and properties of welded steel pipe such as square steel pipe vary. Spiral welded pipe is stronger than straight welded pipe although both of them can be used for transportation and structure, but for some high requirements, the former pipe is more common.

By the above comparison, we can know the use of straight seam welded pipe and gain the understanding of the type and application of welded steel pipe is very essential. What is the difference between square steel pipe and round steel pipe? Actually, the square steel pipe has more application in the construction structure because the rectangle structure is stronger than that of round steel pipe. Of course, steel pipe manufacturers should give full play to the concentrated advantages of steel pipe suppliers. It is believed that this kind of steel tube will develop better in production and application.
