The most serious interference affect hose life

Hose and a hard object edges direct point contact , the contact point by the weight of the hose and the pressure of the high-frequency vibration is also a hard object in the repeated friction on the edges to damage the hose . When the hose is worn outer layer enhancement Hydraulic pipe fittings  layer when exposed to the outside world by the external harsh environment erosion and failure. This is the minimum burst pressure is reduced , the peak is very capacity hydraulic shock exceed the minimum burst pressure , followed by burst pipes, so the enhancement layer is not protected against external corrosion to extend hose life is very important. In order to avoid interference worn outer layer , generally between the hose and the material shall not be less than 10mm / m.
