what is hoop's stresses in pipes and their ratios.

Question

Accepted Answer

Hoop stresses in pipes are circumferential stresses that occur due to internal pressure, and their ratios are important for determining the safety of the pipe.

Hoop stress is calculated using the formula: P*D/2t, where P is the internal pressure, D is the diameter of the pipe, and t is the thickness of the pipe wall.
The ratio of hoop stress to longitudinal stress is important in determining the safety factor of the pipe. A lower ratio indicates a safer design.
In thick-walled pipes, the hoop stress is the dominant stress component, while in thin-walled pipes, the longitudinal stress may be more significant.
