With the continuous expansion of applications, the types of welded pipes on the market are becoming more and more abundant nowadays. At the same time, in order to facilitate the distinction, we adopt different classification methods.
Usually, the blank used for welded pipe is nothing more than two material types, namely steel plate and strip steel. Because of the different welding processes adopted, it can be divided into furnace welded pipe, electric welding pipe and automatic arc welding pipe. If it is classified according to the welding form, it can be divided into two types: longitudinal welded pipe and spiral welded pipe. In addition, according to the different shapes of the ends, it can also be divided into circular welded pipes and special-shaped welded pipes.
On the whole, the classification of welded pipe in the industry is divided mainly in combination with material and use. It can be divided into low pressure fluid transport welded pipe, mineral fluid conveying welded pipe, stainless steel welded pipe for mechanical structure, stainless steel welded steel pipe for fluid transportation and stainless steel tube for decoration. As well as the heat exchanger with welded steel pipe and so on.
The so-called welded pipe for low pressure fluid transportation is mainly used for conveying low pressure fluid and other service pipes such as water and gas in practical application. The common material is Q235 a grade steel. While mine fluid transportation welding steel pipe is mainly used for mine pressure, drainage, shaft gas discharge straight seam welded steel pipe. In addition, Wuxi welded pipe also includes stainless steel welded pipes for building decoration.
