Problems and solutions for flexible metal hose
Aging
Observe the hose surface for aging phenomena such as cracks, hardening, brittleness or loss of elasticity. After long-term use, rubber will gradually age due to environmental factors. If the degree of aging is severe, it will affect the performance and safety of the air hose.
Wear
Check the rubber air hose surface for obvious wear, scratches or damage. If the wear area is deep, the wall thickness of the hose is significantly thinner, or there is penetrating damage, which will cause air leakage. At this time, replace it in time.
Bulge
Check whether the hose has bulges. This may be caused by internal structural damage or excessive local pressure. Hoses with bulges are prone to rupture. Thus you should replace as soon as possible.
Discoloration
If the color of the hose changes significantly, it may be eroded by chemicals or affected by long-term high temperature. At this time, its performance may have changed. Therefore, you should evaluate whether to replace it.
Flexibility check
Bend the hose manually and feel its flexibility. If the hose becomes stiff and difficult to bend, or cracks or abnormal sounds appear when bending, it indicates that its flexibility is insufficient. Then you should replace it.
