Abstract An approximate procedure for calculating the limiting stress-strain state (SSS) of helically corrugated pipes that operate under an axial force is developed. The calculation reduces to determination of the elastoplastic SSS of a shell of revolution with a circular corrugation, which is under axial and torsional loads. The problem is solved using the geometrically nonlinear theory of shells in a quadratic approximation based on Kirchhoff-Love hypotheses, and relationships of the theory of deformation with respect to low-curvature trajectories. The SSS of a self-compensating helically corrugated pipe is investigated, the limiting axial load estimated, and good correspondence between the results obtained and experimental data indicated on the basis of the procedure that we developed.
