The core advantage of this equipment lies in its working mode of “Spiral Feeding + Multi-directional Straightening”. By arranging the axes of the straightening rolls at a certain oblique angle to the pipe axis, the steel pipe naturally undergoes a rotational movement as it passes through. This ensures uniform stress distribution on every part of the pipe body, effectively eliminating composite defects such as longitudinal bending, local dents, and cross-sectional ellipticity. This all-dimensional straightening mechanism is particularly suitable for high-precision and high-volume round pipe production requirements.
