Improving the Wall Thickness Accuracy of Reinforced 3PE Anti-corrosion Steel Pipe

Now the application of reinforced 3pe anti-corrosion steel pipe is more, however, because the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipe is not high, there is a phenomenon of uneven thickness, which will have a great impact on the performance of reinforced 3pe anti-corrosion steel pipe, thus It affects the service life of reinforced 3pe anti-corrosion steel pipes. Therefore, manufacturers of reinforced 3pe anti-corrosion steel pipes have taken some effective measures to improve the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipes.
1. For the heating of the tube billet, it is necessary to pay attention to the uniform heating, and it is forbidden to raise and lower the temperature rapidly, and the temperature should be kept stable.
2. Use the centering roller to determine whether it is in place, adjust the central axis and opening angle of the core-holding roller, etc.
3. The rolling tools should be installed on the rolling line to ensure that the upper and lower roller distances are equal and the left and right guide distances are equal.
4. For the rolling mandrel, choose pipes with larger wall thickness for processing. Pipes with uniform wall thickness can reduce the probability of mandrel deformation and improve the accuracy of steel pipe wall thickness.
5. Improve the process, which can also improve the accuracy of the wall thickness, and avoid the situation that the middle is thinned and the wall thickness exceeds the control range.
