Handling high-pressure hydraulics is serious business. It often involves working in confined spaces, lifting heavy machine parts or dealing with weather extremes in remote locations.To make engineers and maintenance personnel better aware of the issues surrounding high-pressure systems, CEJN, a quick-connect coupling manufacturer recently published a white paper, “Safety Guidelines for Ultra High-Pressure Hydraulic Applications.” It offers safety advice and practical tips for working with high-pressure hydraulic tools.

Here are a few examples.

Respect pressure
CEJN engineers stress that extreme pressure demands a high level of safety, as a leak or accidental disconnection could be catastrophic. Hose assemblies may fail abruptly and unexpectedly for any number of reasons, and oil shooting out at high pressure and velocity can cause serious personal injury and severe damage to equipment and products. Resulting environmental pollution can also demand costly cleanup.

Potential hazards include burst hose, whipping hose ends, oil-spray leakage, and coupling blow-off. It is critical to shut down machinery immediately if a leak occurs. And never, ever, try to locate the leak with your hands, or any other part of the body when a hose set is pressurized. Instead, use a suitable implement to inspect for hose damage.And if a fluid-injection injury occurs, treat it as a medical emergency and seek immediate treatment.

Don’t mix quick-connect couplings
Don’t mix quick-connect coupling halves from different manufacturers. And do not mix genuine products from a reputable manufacturer with so-called interchangeable parts from other suppliers. Unfortunately, this is especially important today when copycat couplings and hoses are circulating on the market.
The interface between coupling and nipple is crucial. The unique tolerances and dimensions engineered into high-quality parts are compromised by mixing brands. And even if the connection seems to fit, this does not mean that the connector will work optimally and safely. In the worst case, it could lead to accidental disconnection and high-pressure oil spray.
