This equipment plays a key role in the finishing of high-frequency straight seam welded pipes. The equipment with vertical structure adopts pairs of rollers (upper and lower) arrangement, capable to bring with higher straightening accuracy and working efficiency.

Generally, there are two rows of straightening rollers, the number of which varies. The pipe straightening machine utilizes the continuous action of multiple sets of straightening rollers to plastically deform and correct the pipe. As the pipe passes through the rollers, it undergoes repeated bending and reverse loading, gradually eliminating internal residual stress and original curvature. By adjusting roller spacing, pressure angle, and compression depth, the machine restores straightness by operating at the critical state between elastic and plastic deformation. High-precision models integrate detection feedback systems to monitor pipe deformation in real-time and dynamically adjust parameters, ensuring uniform straightening.

Value Highlights

• Heavy-duty design and mechanically rugged structure to guarantee a long-term continuous heavy-loaded operation.
• High strength and hardness design on rolls to guarantee a higher straightening accuracy and sustained heavy-duty performance
• Automatic roll setting available as option. One-click to choose the recipe saved in database about the roller spacing, pressure angle and compression depth while changing sizes and specifications, bringing with convenience and high efficiency

The first upper roll featured with quick lift as option to prevent pipe end dented when pipe entering straightening rolls, and it will press down to straighten the pipe as the pipe comes in
