How to improve the wall thickness accuracy of reinforced 3pe anticorrosive steel pipe

1. For the heating of the tube billet, it is necessary to pay attention to uniform heating, prohibit rapid rise and fall of temperature, and maintain a stable rise and fall of temperature.
2. Use the centering roller to determine whether it is in place, and adjust the center axis and opening angle of the core-holding roller.
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 guide distances are equal.
4. The mandrel of the rolling mill should be processed with a pipe with a larger wall thickness. The pipe with a uniform wall thickness can reduce the probability of deformation of the mandrel and improve the accuracy of the steel pipe wall thickness.
5. improve the process, which can also improve the accuracy of the wall thickness and avoid the situation of intermediate thinning and the wall thickness exceeding the control range.
