Which material property of hydraulic lines is crucial for withstanding pressure surges?

The wall thickness of hydraulic lines is a critical material property for withstanding pressure surges. When hydraulic systems operate, they often experience rapid changes in pressure, which can generate high stress on the lines. A thicker wall strengthens the overall structure of the hydraulic line, allowing it to withstand these surges without risk of bursting or failing.

This ability to resist internal pressure is essential not just for safety—but also to ensure the reliability of the hydraulic system as a whole. Lines that are engineered with the appropriate wall thickness can maintain their integrity under various operational conditions, including potential pressure spikes during system activation or component failures.

While aspects like length, flexibility, and weight are important considerations in the design and functionality of hydraulic lines, they do not directly impact the ability of the lines to handle pressure surges as significantly as wall thickness does. These characteristics may affect installation, operational range, or system response time but do not primarily determine the structural strength needed to resist the stresses imposed by sudden increases in fluid pressure.
