Connection is key to fluid power system efficiency

Compatibility

Another key factor to consider is compatibility. It can be all too easy for a system to be specified without properly considering whether the tube compound is compatible with the fluid. A chemical resistance chart is a good tool, enabling the specifying to select a hose, hose tube, couplings, cover and O-rings that are consistent with the demands of the fluids. Failure to do so can lead to permeation, which will in turn result in loss of fluid within the system. Compatibility is also an important consideration on the braids, fittings and components yet, they are often forgotten during the specification process. Yet, systems exposed to aggressive fluids, can result in catastrophic failure and even major health and safety implications.

International thread terminations are available in different formats with BSP, Metric, JIC and SAE among the most frequently used. Knowing the equipment’s country of origin is a great starting point when selecting what thread end is used. It’s important to be aware of these differences and ensure that the system components are compatible and therefore safe for use on site.

Interestingly and unknown amongst much of industry is the testing and validation of the hose and coupling interface under strict testing parameters. Eriks is in fact one of a handful of distributors with the capability to test and validate both its own hose and coupling combinations as well as bespoke solutions for clients; ensuring efficiencies on site are met and more importantly that the safety of employees working in and around these connections can be assured.

Regular inspections

Achieving maximum hose performance and safety requires regular inspections of the hose and components prior to, during and after use. Hoses that have become worn or damaged can present a danger to employees and should be replaced immediately.

While testing and validation is imperative pre-installation, failure to properly maintain hoses can also have serious consequences, such as costly material spills, clean-up, downtime and injury. However, regular scheduled inspections, corrective measures and hose replacements can be far less expensive than replacement or repairs made after a failure.

Weak link

It’s vitally important to be aware of all the factors involved when specifying hose and coupling equipment. Get it wrong and a hose assembly is potentially the weak link in your production process. It can be an entrance point for contamination or leakage and a health and safety risk. Get it right and a high-quality hose assembly will not only maintain a fluid system’s efficiency and reliability, but can play a key role in your plant’s performance.
