Hoses, fittings and hose assemblies all contribute to this by transmitting fluids at high pressures. Hose inspection and failure - Hydraulic power is accomplished by using high-pressure fluids to transfer energy and do work. They may also be subject to internal mechanical and/or chemical wear from the conveying fluid and may fail without warning.ĥ. Hose assemblies and elastomeric seals should be inspected and replaced at specific replacement intervals, based on previous service life, government or industry recommendations, or when failures could result in unacceptable downtime, damage, or injury risk. Replacement intervals - Hose assemblies and elastomeric seals used on hose fittings and adapters will eventually age, harden, wear and deteriorate under thermal cycling and compression set. Ensure that hose is not operating outside of its published maximum working pressure and that surge or peak pressures are also below this point.Ĥ. Personnel must avoid potential hazardous areas while testing and using the system. Functional test - Operate the system at maximum operating pressure and check for possible malfunctions and leaks. Inspecting for hose abrasion is critical in hose maintenance.ģ.
