1. Carefully observe the steel pipe straightness, the initial adjustment to ensure that the steel pipe and straightening roller body three-fourths contact, and ensure that its clearance is not greater than 0.1mm.
2. Straightening speed should be adjusted according to the bending degree of the steel pipe and the material of the steel pipe.
3. According to the material of the steel pipe, bending degree and the required precision to adjust the distance between the upper and lower rollers to ensure that the amount of straightening pressure.
4. In the process of the pipe is prohibited by hand touching the straightening roller and the movement of the steel pipe, and pay attention to the surface quality of steel pipe to prevent the surface scratches and indentation.
