hoop stress longitudinal 1hoop stress 1Hoop stress, abbreviated as \( \sigma_h \) (Greek symbol sigma), is the circumferential and perpendicular stress to the axis imposed on a cylinder wall when exposed to an internal pressure load.

  • Factors and conditions affecting pipe wall thickness:
    • Maximum conditions such as pressure and temperature
    • Fluid properties
    • Fluid velocity
    • Pipe Materials
    • Safety of design factors
  • Three stresses that will cause failure in pipe:
    • Axial stress  \(h\)
    • Hoop stress  \(\theta\)
    • Radial stress  \(r\)
