Spiral Hydraulic Hose Shelf life in SAE Standard

Do you know how many years the Society of Automotive Engineers (SAE) usually limits the standard shelf life of unused bulk spiral hydraulic hoses? It is 10 years. But the service life of spiral high pressure hydraulic hose will not reach 10 years at all. Factors such as operating conditions, ambient temperature, pressure, and the type of hydraulic fluid all play a role in how long a spiral hydraulic hose survives in service. The high pressure 4 wire hydraulic hoses, such as, EN 856 4SH, EN856 4SP, SAE 100 R12. SAE 100 R13, SAE 100 R15 often work in harsh environment, their service life is more easily to shorten. 

So for safety, Most spiral hydraulic hoses are designed to pass the cyclical impulse pressure requirements at specific pressure levels above the rated working pressure, temperature and bend radius.This qualification testing requires the use and assembly with the properly specified end fittings attached to the spiral hydraulic hose for a number of cycles.  

Most two wire braid hydraulic hose require a successful testing of a minimum of 200,000 pressure impulse cycles, while most wire spiral hoses require at least 500,000 cycles. This is why spiral hydraulic hoses are normally considered longer service life hoses. 

Hydraulic Hose Manufacturers Extend Wire Spiral Hose Shelf Life

While in fact, most hydraulic hose manufacturers exceed the SAE impulse standard to  extend spiral hydraulic hose shelf life. Evergood hydraulic hose company produce spiral hydraulic hose with anti-million impulse. Our 4 wire hydraulic hose EN 856 4SH, EN856 4SP, SAE 100 R12, SAE 100 R13, SAE 100 R15, etc, can work under high pressure for a long time. Super oil resistant Korea LG rubber make spiral high pressure hydraulic hose more sturdy and stronger to fight with oil fluids.

Extend Spiral Hydraulic Hose Shelf Life methods for users

Besides the hydraulic hose manufacturing process, the following precautions will also help extend the service life of spiral hydraulic hose.

• Protect spiral hydraulic hose against wind, rain, sun, and temperature
• Clean dirt and water in the hydraulic fluid
• Use Protective sleeves to protect spiral hydraulic hose 
• .......

These protections are important, but it is more important to buy a high-quality spiral hydraulic hose. Evergood high pressure hydraulic hose is specially designed for harsh environments and provides one-year warranty service. Contact us to learn more!
