Hose testing of quality

Inner adhesive layer is a medium hose contact work, prolonged immersion medium, corrosion, friction, also sealed media, the role of protection layer. In order to meet the work requirement, requires an inner adhesive layer has a certain thickness, temperature, corrosion resistance, wear resistance, but also has some tightness, flexibility and strength. Enhanced layer is the part of the hose under pressure, across the hose with the necessary stiffness and strength. Hose is a hose layer of the outer cover, due to the contact with the external environment, not only requires wear resistance, has a certain thickness, also calls for a certain degree of corrosion resistance and aging resistance.
