At present, the seamless steel pipe has been widely used in many fields and plays more and more important roles. And in general, the seamless steel pipe features are smaller outer diameter, high precision to carry out production with small scale. And the seamless steel pipe uses cold roll technology to endow the seamless steel pipe with higher precision with more complex across-area of the seamless steel pipe. Another seamless steel pipe feature is its more outstanding performance with more thick metals.

In addition, the seamless steel pipe has thick walls to make sure the economical efficiency and practical ability of the seamless steel pipe. The thinner the walls of the seamless steel pipe are, the more their process cost will increase. And the technique of the seamless steel pipe decides its limitation. Generally, the seamless steel pipe has lower precision than API steel pipe. And the walls of the seamless steel pipe are no uniform with low brightness both of inner walls and outer walls of the seamless steel pipes. And there are some black spots on the surface of the seamless steel pipe due to the technique limitation of the seamless steel pipe. Another seamless steel pipe feature is that the inspection and formation of the seamless steel pipe must be carried out off-line processing. Therefore, the seamless steel pipe has superiority in the aspect of high pressure, high intensity as well as mechanical structure and materials.

The seamless steel pipe feature also includes its classification. The seamless steel pipe can be classified into hot rolling, hot extrusion as well as cold rolling according to its technique. And the seamless steel pipe also is able to be classified into half ferrite and half martensitic stainless steel, martensitic stainless steel, austenite stainless steel as well as austenite-martensitic stainless steel according to stainless metallographic structure.

In addition, the mechanical production eliminates the defects like cracks, folds, chaps, flaws, separation layer as well as scab. After elimination, these defects will not make the wall thickness and outer diameter exceed minus deviation. And due to the technique of seamless manufacturing, the seamless steel pipe is able to deliver liquid like water and oil perfectly. And the water proof and corrosion resistance performance makes it able to be the ideal material for liquid delivering. And the seamless steel pipe is playing more and more important role in modern society for construction materials due to its unique seamless steel pipe features. In conclusion, the seamless steel pipe features make it superior to other kinds of steel pipes to a great extent. And the mechanical manufacturing makes sure complete process and favorable quality of the finished seamless steel pipe. The future of the seamless steel pipe is bound to be better and better.
