WIRE – WOUND THIN CYLINDER

From article 5.1.2, the hoop stress on the thin cylinder is two times the longitudinal stress. Hence the failure of a thin cylinder will be due to hoop stress. The hoop stress due to internal fluid pressure is also tensile in nature. In order to increase the tensile strength of a thin cylinder to withstand high internal pressure without excessive increase in wall thickness, they are sometimes prestressed by winding with a steel wire under tension. The effect of the wire is to put the cylinder wall under an initial compressive stress. If now a fluid pressure is applied into the pipe, the bursting force will be resisted jointly by the pipe as well as the wires. A pipe closely wound by wires can therefore withstand a higher fluid pressure than an unbound pipe.
