Which type of tubing requires a greater minimum bend radius?

Steel tubing over 1.5 inches OD requires a greater minimum bend radius due to its rigidity and thickness compared to other materials. The physical properties of steel, especially in larger diameters, limit the degree to which it can be bent without risking structural integrity or causing kinking. Proper bending techniques must be employed to avoid damage, making it essential to adhere to specified minimum bend radius requirements for this tubing.

In contrast, aluminum alloy, copper, and plastic tubing often have greater flexibility and can be bent more easily without requiring such large radii, allowing for tighter turns in installation. This flexibility often results in lower minimum bend radius requirements for these materials.
