How to improve the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipe

1. For the heating of the tube blank, we must pay attention to uniform heating, prohibit the rapid rise and fall of the temperature, and keep the rise and fall of the temperature stable.

2. Use the centering roller to determine whether it is in place, and adjust the core roller's center axis and opening angle.

3. The rolling tools should be installed on the rolling line to ensure that the upper and lower roll distances are equal, and the left and right lead distances are equal.

4. The rolling mandrel chooses the pipe with a larger wall thickness for processing, and the pipe with uniform wall thickness can reduce the probability of deformation of the mandrel and improve the wall thickness accuracy of the steel pipe.

5. Improve the process, which can also improve the wall thickness accuracy and avoid the middle being thinned and the wall thickness exceeding the control range.
