The impact toughness of petroleum cracking pipe is the ability of materials to resist deformation and fracture under impact load.

If the 16Mn seamless steel pipe is welded well, its performance and advantages will be greatly improved.

Control the layered structure of seamless steel pipes from the following three aspects: improve the plastic ductility of the structural steel pipe; effectively manipulate the heating temperature; reduce the roll speed ratio.

There are mainly two types of test methods for 16Mn seamless steel pipes.One is the static test method and Another type of test method is the dynamic test method.

The quenching stress at room temperature and the quenching stress at zero are superimposed, and cold treatment cracks are formed when the stack response force exceeds the strength limit of the material.

The color of the precision tube becomes unsightly after rust. These methods can solve this problem.
