Non-destructive testing and evaluation of technical state of steel technological pipelines of coal enterprises

E. S. Krylov, V. A. Kulish

 
Complex evaluation of technical state by grade system was developed for steel technological pipelines of coal enterprises. The criteria for evaluation are the factors effecting technical state of the pipelines. The KARAT complex of acoustic-emission testing was developed for leakage detection as well as determination of defects of crack type propagating at loading in pipe metal. Branch standard GSTU 101.00174125.002-2003 was developed based on research results. Ref. 10. Tables 2, Figures 2.
