What is the minimum bend radius for a MIL-H-8788-10 hydraulic hose operating at 1,200 psi and 210º centigrade through 60º travel?

The determination of the minimum bend radius for hydraulic hoses is crucial to ensure that the hose performs effectively without suffering structural damage or affecting the hydraulic system's performance. For a MIL-H-8788-10 hydraulic hose operating at 1,200 psi and a high temperature of 210º centigrade, it is essential to consider the hose's specifications and the operational parameters.

The correct choice of a minimum bend radius of 7-1/2 inches is based on established guidelines for hydraulic hose performance under specific pressure and temperature conditions. MIL-H-8788 hoses are designed to withstand significant operational stresses, but excessive bending can lead to kinking, cracking, or other forms of damage that compromise the integrity of the hose.

In this case, the minimum bend radius is dictated not only by the internal pressure and temperature but also by the travel angle of 60º. The combination of these factors necessitates a relatively larger bend radius to maintain safety and functionality. Therefore, the specification of 7-1/2 inches aligns with the industry standards for hydraulic hoses under these conditions, ensuring that the hose can operate effectively without risk of damage.

Understanding these parameters helps in maintaining system reliability and safety, which is why choosing the correct minimum bend radius is
