Hydrostatic testing is an important process that works to help distinguish whether a hose has a fault or not. Leaking or faulty hoses cause millions of pounds worth of damage, losses and slows productivity around the world. Faulty applications in the most dangerous industries can even cause fatalities, which really emphasises the importance of ensuring your hoses and applications are kept under strict management – ensuring efficiency safety and reliability.
When a hose undergoes a hydrostatic test, the pressure is tested at around 1.5 times more than the maximum working pressure. The pressure is then held for a set period of time and is closely monitored with extreme advanced testing technology.
The process is performed to help expose defective materials that have missed prior to detection that could include deteriorated strengths and leaks. Specialist technology companies have custom built rigs that run with highly sensitive computer aided tracking equipment to allow the most accurate testing available within the hose testing industry.
By having the hydrostatic testing process undertaken on your equipment, you are ensuring that you are going to get an accurate analysis upon the integrity of your systems. The process involves placing the pressure vessel into a closed system; usually, a test jacket filled with water and a specified internal water pressure is then applied to the container inside of the closed system.
The vessel is tested with incompressible fluid – like water or oil before it is placed in a process to be monitored closely. The fluids passing through the hose without leakages will confirm that the hose is safe to use. Just because a hose has no visually obvious signs of damage, it does not mean that the hose is safe to use.
Hydrostatic testing aims to help determine the strength of cylinders, pipes and other vessels, along with other tests used to make sure that the material is of a suitable quality. Magnetic particle inspection and liquid penetrate inspection is used to test for cracks on the surfaces, which are conducted as per industrial compliance as a part of safety maintenance.
