Material Preparation
Steel pipe is made of a very high quality kind of round steel as the main material.
Steel Searcher-Steel Pipe having a hollow section much longer than its diameter or circumference. According to the sectional shape, it can be divided into round, square, rectangular and special-shaped steel tubes; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to the purpose, it can be divided into conveying pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high pressure equipment and so on.
Steel pipe is made of a very high quality kind of round steel as the main material.
The principle of perforation is to use high temperature make the round steel for a softening work and then the top of the middle of the solid part are all removed. This time it becomes hollow round steel, which is what we see seamless steel pipe.
Then do the round steel perforation, in the process of perforation, when the solid round steel turns into a hollow round steel.
Then Straightening, inner grinding, deviation correction, outer grinding, flaw detection, finishing, final inspection and packaging.
