Hose structure is usually divided into: the inner layer, the outer layer and the skeleton layer (or intermediate layer). The tube directly bear the conveying medium wear, erosion; the outer layer to protect the body from the external environment of hose damage and erosion; skeleton layer is the layer of pressure hose, tube gives strength and stiffness. Hose working pressure depends on the material and structure of the skeleton layer.

Full rubber hose
Different skeleton layer, the common hose are:
Full rubber hose (no fabric material)
Fabric hose (skeleton layer is a fabric layer)
2 fabric hose
Fabric hose
Suction hose (outer fabric layer and a layer of metal spiral for work under vacuum conditions)
Braided hose (skeleton layer of woven wire or fabric)
Winding hose (skeleton layer wire or cord winding layer, endurance is common in 80 ~ 600MPa even higher pressures)
3 foam hose
Suction hose
Knitted hose (skeleton layer knitted fabric)
