How to improve the wall thickness accuracy of reinforced 3PE anti-corrosion steel pipes

At present, reinforced 3PE anti-corrosion steel pipes are widely used. However, due to the low wall thickness accuracy of reinforced 3PE anti-corrosion steel pipes, uneven thickness occurs, which will have a great impact on the performance of reinforced 3PE anti-corrosion steel pipes, thereby affecting the service life of reinforced 3PE anti-corrosion steel pipes. Therefore, to improve the wall thickness accuracy of reinforced 3PE anti-corrosion steel pipes, reinforced 3PE anti-corrosion steel pipe manufacturers have taken some effective measures.

How to improve the wall thickness accuracy of reinforced 3PE anti-corrosion steel pipes?
1. For the heating of the pipe blank, it is necessary to pay attention to uniform heating, prohibit rapid temperature rise and fall, and keep the temperature rise and fall stable.
2. Use the centering roller to determine whether it is in place, adjust the center axis and opening angle of the core roller, etc.
3. The rolling tool should be installed on the rolling line to ensure that the upper and lower roller spacings are equal and the left and right guide spacings are equal.
4. The mandrel of the rolling mill selects pipes with larger wall thickness for processing. Pipes with uniform wall thickness can reduce the probability of mandrel deformation 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 situation of thinning in the middle and wall thickness exceeding the control range.
