What are the two types of lines used in a hydraulic system?

In a hydraulic system, the two types of lines used are rigid and flexible. Rigid lines are typically made of metal and are used in areas where a solid structure is needed to withstand high pressure without deforming. They maintain their shape and can handle the stress of the fluid movement, providing a reliable pathway for the hydraulic fluid. On the other hand, flexible lines, which are often made of rubber or other materials, allow for movement and flexibility within the system. This is crucial in areas where components may shift or vibrate, ensuring that the fluid can still flow without risk of leakage or damage. Understanding the distinction between these two types of lines is essential for ensuring the integrity and proper functionality of hydraulic systems in aerospace applications.
