Read about START-PROF pipe stress analysis software
Analyzes pipe cross-section stability against external pressure Pwork in vacuum service. Analysis per GOST 32388-2013 with adjustment No. 1.
Stiffening rings at specified intervals increase external pressure stability.
K - stability factor, Ky - stability factor under combined external pressure, axial force, bending moment, and shear force.
