High pressure hose for the oil and rubber inner wall

High pressure hose for the oil and rubber inner wall, in the middle of braided steel wire (steel braided hose) or winding wire (wire winding hose). Poor quality of the hose will appear: plastic wall of uneven thickness; steel braided too tight (wire stroke is small), too loose (steel travel large) or wire root too few; hose pressurized deformation Hydraulic adapters (elongation, shortening or bending deformation) larger (national standard steel stroke control of plus or minus 3); airtight plastic outer lead wire corrosion poor (main manifestations: Lu steel); inner plastic seal is poor leaving the high pressure oil easily into wire layer; adhesion layer and layer of wires inadequate. The above conditions can cause the hose to withstand reduced, eventually appears at the wall of the weak burst. Especially in the inner layer, poor air tightness, then a pressure, it leaks, then the pressure directly burst.
