Abstract
A design criteria is developed for the axial length effect of pressurized multiple layered spiral wound hose with clamped end couplings. Upon application of hydraulic pressure, the hose section in the vicinity of the clamped end is assumed to deform from a right circular cylinder to a truncated cone with constant wire helix angle. The solution obtained from solving equations of equilibrium for a single naturally curved thin rod experiencing small axial deformation is used to piece-together a layer solution which in turn is plied-up to form a complete hose. Continuity of solutions at the interface of the conical and cylindrical regions is enforced. This enabled transition zone length (axial length of cone) to be expressed as function of hose geometry. Both four and six-layered hose with inside diameters 1.0, 1.25, and 2.0 inches (25.4, 31.8, and 50.8 mm) are considered.
