Hydraulic hose failure is a serious problem, regardless of the industry or type of equipment involved. Hose failure can lead to downtime of the machine and the entire system, as well as costly maintenance costs and other financial losses. If high-pressure equipment is involved, employees may be at physical risk in the event of a hose failure.
3. High temperature and heat aging lead to hydraulic hose failure
When hoses are exposed to extreme temperatures, they lose elasticity and harden. High temperatures cause the plasticizer in the elastic tube to rupture, then harden and begin to rupture. Over time, these cracks will eventually reach the outside of the hose. If you remove the hose, a cracking sound at the bend or the bending shape does not bounce back, it is due to thermal aging.
In order to minimize the impact of thermal aging, avoid unnecessary operation of hoses in high temperature areas, and confirm that the rated temperature of the hose is suitable for continuous operating temperature. If thermal exposure cannot be avoided, consider using a thermal protection device on the hose, such as Silicone Fire Sleeve.
4. Failure of hose caused by corrosion
Corrosion occurs in the inner tube, usually caused by concentrated high-speed fluids (which may be present in particles). The fluid gradually erodes the inner tube of the hose, and an external leak may occur as the erosion continues.
One of the best ways to prevent hose corrosion is to determine the size of the hose with the maximum expected flow rate. Another way to minimize the impact of hose corrosion is to verify that the abrasion of the fluid is compatible with the type of hose used, that is, to select a type of hose that is resistant to corrosion.
