The inner wall of the high pressure hose for oil resistant rubber

The inner wall of the high pressure hose for oil resistant rubber, the middle braided wire (steel wire braided hose) or winding steel wire (wire wound hose)
The inner wall of the high pressure hose for oil resistant Hydraulic pipe fittings, the middle braided wire (steel wire braided hose) or winding steel wire (wire wound hose). The poor quality of the hose will appear: tube wall is uneven; steel wire braided tightly (wire small stroke), too loose (steel large stroke) or the number of the steel wire is too small; hose compression deformation (elongation, shortening or bending deformation (national standard) larger wire stroke control within plus or minus 3); the outer layerhydraulic hoses air tightness differences lead to corrosion of the steel wire (main forms: bare wire); the inner layer glue sealing difference and make the high-pressure oil easily into the wire layer; adhesive layer and the steel wire layer adhesion deficiency. This will make the hose to bear force is reduced, finally appear in the weak point of tube wall burst. Especially in the inner layer, poor air tightness of words, a compression, it Water Leakage, then directly burst pressure.
