Methods to Improve the Precision of Cold Drawn Steel Pipe Wall Thickness
(1) Properly adjusting the piercing and rolling process parameters improves the accuracy of rolling mill tools, ensuring uniform deformation of billets and rough pipes during the piercing and rolling process.
(2) Precisely adjust the centering position, install a roller support device to align the top head with the center of the billet, and prevent off-center piercing.
(3) Securely install and adjust the roller, then tighten the top rod to prevent it from sinking.
(4) Implement equipment scheduled maintenance to ensure the equipment remains in good condition and guarantees the accuracy of the wall thickness of the tubes.
(5) Enhance management by regularly measuring capillary wall thickness and promptly adjusting issues as they arise.
