Medium in the rubber hose
In general, a rubber hose has its special use. For example, rubber water hose is to deliver water. But you can not use it to deliver oil. Because each special rubber tube adopts special material. Thus if you use it to deliver wrong medium, it may cause failure. It’s true that there are multipurpose hoses. But most of them are for unique use.
Each hose has certain working condition limits. While you should use the hose within such limits. Because if you use it beyond those, it will cause damage to the hose and reduce the service life.
Using it below the bending radius will greatly reduce the life of the hose. In addition, avoid the bends at the ends of the connectors.
Never make the hose work in a twisted state. Because that will damage the rubber pipe and reduce the lifespan.
Vibration of the hose
The thermal stress and fatigue stress that vibrations subject the hose to can cause cracks near the joints. Therefore, test the stress-bearing capacity of the hose before leaving the factory.
Some users tend to impede the flow of fluid by kinking the hose. This method is not a good choice. Because it may lead to rupture due to excessive stress on the reinforce layer.
Choose a proper fitting
Check if the pressure of the hose and joint fit each other. Connect with a diameter that is too large will cause abnormal stress. Then it will tear the hose reinforce layer. While connect with a diameter that is too small will make it difficult to fasten and cause leakage. In addition, joints must avoid sharp edges, which may damage the rubber hose. Water or soapy water can be used to assemble couplings. Do not use oils or solvents for assembly unless the hose is to convey these mediums. Do not use a mallet or similar tool to soften the hose.
