Cylinder Hoop Stress

Cylinder hoop stress, abbreviated as $\sigma$ (Greek symbol sigma), is the circumference stress in a cylinder of pipe having both ends closed due to internal pressure.

Cylinder Hoop Stress Formulas
$\sigma_h \;=\; ( D \;/\; 2 \; t ) \; ( p_i - p_e )$ (Thin Wall Pipe) $\sigma \;=\; p_i \; d \;/\; 2 \; t$
