Hydraulic lines - Import export

Non-rotating asset components seldom receive the routine surveillance they need Hydraulic systems represent another way industry converts electricity to mechanical energy. A pump, normally powered by an electric motor, moves hydraulic fluid through a system. The system is typically made up of a reservoir to hold the hydraulic fluid, high pressure lines to carry the fluid, control valves that ensure the fluid is sent where needed, relief valves for safety, and cylinders to produce mechanical energy. The pump and motor receive attention while the balance of the system is run-to-failure. Ultrasound testing could change this lackadaisical approach; especially considering its versatility, ease of use, and applicability to most hydraulic defects. External and Internal Leaks External leaks can often be found by visual inspection. Some external leaks, like a ruptured hose or fitting, are easy to spot. Simply follow the trail of spilled oil. Others are not so obvious.
