Research of Supporting Ability and Prediction of Residual Life of Casing Pipes at General Corrosion Damage of Inner Surface

The detection and the measuring of developing damages must be accompanied by evaluation supporting ability design in terms increasing size a defect. If type damage is dominant one on further period operation, so received functional dependences can used to predict residual life designs. As illustrated casing pipes 168.3 mm diameter, where general corrosion inner surface, algorithm receive expression for calculation coefficients lowering excessive pressure function nominal thickness wall depth shown. application calculate damaged given.
