Method of making wire braid hydraulic hose
Abstract
Abstract A method of making a wire braid hydraulic hose which when made according to certain specifications will have a known average burst pressure and a known average life of pressure impulse cycles wherein the hose is subjected, immediately after curing, to an internal pressure of approximately 80 to 95 percent of the known burst pressure, maintaining said pressure momentarily and relieving the same whereby the individual wires of the braid will be realigned and repositioned into a permanent close contact with each other so as to substantially increase the strength of the hose and increase the number of pressure impulse cycles it will withstand well above the known average to thereby increase the life expectancy of the hose.
