Visual inspections should be performed before each use and before hydro static testing
Thorough visual inspections should occur at least every 6 months
Inspect for the following:
Abrasion damage to cover such as wearing away, tears, or cuts
Cover damage such as dents, kinks and swelling
Displacement of wires
Corrosion and damage of external wire
Damage and displacement of end fittings
Signs of softening or weakening
Other signs of wear and damage to the hose and end fittings
Testing: (Hydrostatic testing should be conducted at least once per year)
A visual inspection should be conducted prior to testing
Do not test hoses that fail visual inspection
Pressurize assembly and hold for 10 minutes. Check for leaks
Test electrical continuity between connections
Reduce pressure and drain hose
If assembly passes test, recheck electrical continuity
Electrical continuity should be checked every 6 months
Cleaning: (Following use, before testing and storage)
Pigging must not be used
Passive flushing is sufficient with such fluids as clean water, detergents, common solvents at ambient temperatures. If sea water is used, drain thoroughly to minimize risk of corrosion to internal wire and fittings
Open ended steam cleaning is suitable as long as max working temperature is not exceeded
Do not exceed max working pressure if using compressed air
