A method of computing stress in pipeline walls, caused by deformation or corrosion defects on the basis of measurements carried out by a special inspection gauge
for CDRiA Pipeline Services
With the use of Flugge thin-shell theory, a method was developed for computing stresses in pipeline walls on the basis of data on its deformations acquired by a special inspection gauge. Analysis in linear range took into account: inspection gauge accuracy and pressure inside pipeline. On the basis of the above-mentioned method, a computer code was developed, which was later introduced into regular use by a main Polish pipeline operator.
