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.

Some rules must be followed when storing seamless steel pipes

The pipe jacking method to produce seamless steel pipes was proposed by Heinrich Erhard of Germany in 1892.
