When using soft rolled tubing, how must it be unrolled and straightened?

When dealing with soft rolled tubing, it is essential to handle it properly to maintain its integrity and functionality. The correct approach is to unroll and straighten the tubing by hand. This method ensures that the tubing doesn’t become kinked or damaged, which can occur if too much force is applied or if it is mishandled with tools or equipment.

Using hands allows for a more controlled and gentle straightening process, minimizing stress on the material. Hand straightening also helps in maintaining the desired curve and ensuring that the tubing can fit appropriately in its intended application, such as entering a compression fitting without difficulties. This technique is especially important as soft rolled tubing is designed to be flexible and malleable, which is compromised if the material is subjected to excessive force or incorrect handling techniques.

In contrast, using rollers, wooden mallets, or focusing only on preparing it for compression fittings may not provide the careful control needed to ensure the tubing remains in optimal condition for use.
