What type of equipment is used for changing the direction of copper tubing?

The correct choice is non-deforming bending equipment, which is specifically designed for changing the direction of copper tubing without compromising its integrity or structure. This equipment often includes devices like bending jigs or hydraulic benders that allow for precise and controlled bends. Using non-deforming methods is essential because they maintain the tube's wall thickness and prevent the formation of kinks that could restrict flow or lead to leaks.

Tools such as heat bending tools can also be used to bend copper tubing, but they do involve altering the physical property of the material, which is why they are not the best option for achieving an accurate and clean bend without deformation. Hammer and anvil, or wrench and pliers, are not suitable for this purpose as they can damage the tubing, leading to potential failures. Therefore, non-deforming bending equipment remains the most appropriate choice for ensuring durable and effective modifications to the direction of copper piping.
