The present invention is directed to an improved metal strips straightener, including an infeed device and a pressure frame. The infeed device has one or more leveling rollers, and the pressure frame has a roller frame. The roller frame has one or more roller blocks to bring a metal strip into a upward full encirclement wrap. Each roller block is attached with a camshaft, where each camshaft is connected to a motorized drive system. Rotation of the camshafts actuates the roller blocks to move the metal strips, applying pressure on the metal strips during the passing through of the roller blocks. A closing cylinder is attached to one end of a roller block, where the closing cylinder has a convex contact surface. Multiple roller blocks are connected to each adjacent roller blocks via their connected closing cylinders.

A method to improve the collapse resistance of metallic tubular products is disclosed. Stress is applied to the metallic tubular products in order to change the residual stress profile of the metallic tubular products, such as those that have completed a straightening process, resulting in a residual stress profile that improves collapse resistance. The metallic tubular product is subjected to radial compression processing to control the residual stress profile and to enhance collapse resistance. The radial compression process may be applied after the tubular product has been subjected to a straightening process.
