In a non-flexing hydraulic installation, which aspect affects the minimum bend radius?

The correct answer is based on the concept that the minimum bend radius of a hydraulic hose is significantly influenced by the operating pressure. When hydraulic systems operate at higher pressures, the fluid within the hoses exerts considerable force on the hose walls, which can lead to deformation if the hose is bent too sharply. This deformation can compromise the integrity of the hose and the hydraulic system overall.

A hose subjected to high operating pressure requires a greater bend radius to maintain optimal flow and prevent kinking or damaging the hose. A tighter bend could lead to restrictions in fluid flow, increased wear, or even failure of the hose over time. Therefore, understanding the operating pressure of the system is critical when determining the appropriate specifications for hose installation, including the minimum bend radius.

Other factors like the flexibility of the hose can influence how easy it is to maneuver the hose, but it's the operating pressure that ultimately dictates the safety and functionality of the installation. Environmental conditions may have an impact on material degradation or performance but are not as directly tied to the minimum bend radius as the operating pressure.
