Annotation:
On the basis of the stress-strain state, the authors of the article investigate the depressurization of a polymer reinforced pipeline loaded by internal pressure and fixed at one end in a rigid seal. To solve the equations of the mathematical model, the finite element method was used in the COMSOL Multiphysics numerical simulation environment. The influence of the load magnitude and fastening methods on the stress-strain state of a polymer reinforced pipeline loaded by internal pressure has been studied, and three-dimensional, flat and one-dimensional distributions of equivalent stresses and strains have been obtained. The depressurization area was determined at a distance of 15 mm from the seal and the possibility of using a cylindrical-conical seal, which increases the depressurization pressure by 30 % was determined. The influence of pipeline damages on stresses distribution was assessed.
