When hose assemblies become broken, leaking or disrupted, there will be usually what’s know as an ‘outage’, which can result in down time to processes that can result in lost time, money, resources and cause disaster that could have been prevented with a simple hose test. A professional and experienced hose inspection and testing firm will offer preventative testing that will virtually eliminate unpleasant unforeseen surprises, allowing both employees and customers to get on with their duties and plans comfortably and safely.
Buckley Industrial are a firm that specilise in the testing of hose assemblies, through an inspection and practical test process that allows them to pick out any potential risks to your hose assemblies, expansion joints, couplings and much more. Depending on the application and process undertaken will determine which type of hose testing will be required.
The different types of hose testing include:
Hydrostatic testing involves filling a hose assembly with water, taking it to around 1.5 times the maximum working pressure and holding it for a period of time that will ensure the hose could deal with unexpected pressure increase. Whilst under this pressure, the hose will be monitored close to ensure that the pressure is held and that the hoses integrity is maintained.
The nitrogen testing process consists of a hose assembly becoming filled with nitrogen, whilst submerged under water and bringing it to a specified test pressure. Any leaks will be detected through emanating bubbles. If a pressure drops, then it is registered on highly sensitive tracking equipment. This type of testing can also be done with different gases if necessary, so it may be wise to speak to the firm you are dealing with to find out more details.
The vacuum testing process is usually employed to test hose assemblies in suction applications which will ensure that they stay completely rigid during their service. Facilities usually enable hose testing firms to subject hose assemblies to any negative pressure reading down to a total state (-29.92inHg – inches of mercury).
Electric Continuity Testing:
This type of testing is perfect for certain applications that require an electrical bond between the end fittings of a hose assembly to avoid creating a static build up within the length of the hose. The testing facility will achieve this through incorporating a conductive material within the hose bonded to the end fittings. Continuity is ascertained by measuring the resistance between two ends of an assembly with the use of a multimeter.
Depending on your application, you may need testing and inspection of one type and not the other. Certain applications can be tested properly with one or two of the test methods, so it is always worth undertaking a little research before approaching a firm. Buckley Industrial offer their hose testing and inspection service to anyone that feels they should have their assemblies, expansion joints, couplings etc tested to avoid devastation that can disrupt important processes.
