The difference between precision seamless steel pipe and seamless steel pipe1 The main feature of the seamless steel pipe ready after oil is that it has no welded seam and can withstand greater pressure than the version. The product can be a rough cast or cold drawn part.2. Precision seamless steel

Seamless steel pipes continue to develop during the entire development trend, and the total number of manufacturers and commodities continues to increase. Due to the large number of seamless steel pipe factories and the relatively large total output in the sales market, many problems have appeared during the entire development trend, among which quality problems and many drawbacks are more typical. In addition, the overproduction of seamless steel pipes is serious, and the development trend of the intermediate field is relatively limited, and the future will also face huge challenges. In the process of the whole development trend, the following problems are mainly encountered:

The seamless steel pipe structure currently used in the project can be classified according to the cross-sectional shape, structural form and manufacturing method. According to the cross-sectional form, seamless steel pipe structure can be divided into three types: round pipe structure (CHS), square
