Aircraft Hose Tube definition
- Contains and directs flow of materials
- Protects the outer parts of the hose from abuse or destruction by the material being conveyed
Notice that the tube doesn't normally provide pressure strength. Thus if you have abraded a hose down to the tube, the ability of the hose to withstand internal pressure is lost. The reinforcement holds back internal pressure, not the tube.
In the manufacturer of tubes, the synthetic rubber stock is mixed to the desired blend and heated in a mill. A continuous strip is cut from the mill and fed into the tuber. A seamless rubber tube is then formed to the desired diameter and wall thickness by a continuous extrusion process wherein the rubber stock is forced through the annulus of a pin and die combination by the pressure generated by a helical screw rotating in a cylinder. The tube is either extruded directly onto a mandrel or extruded and then mounted on a mandrel for the hose-making operations either by drawing the tube over the mandrel or by pushing the mandrel through the tube using air pressure to momentarily enlarge the tube.
In some instances, such as large I.D. hose, the tube is made by the build-up method. Sheets or strips of tube stock are spirally wound around a mandrel, then reinforced. During vulcanization, the tube becomes a solid mass.
