Abstract
Example is given of the efficient application of explosion energy for improving reliability of process equipment installed at the Nikolaev Alumina Plant by relieving residual welding stresses in welds on decomposers and mixers with a diameter of up to 14 m and height of up to 34 m.
Keywords: explosion treatment, welded decomposers, mixers, welds, residual stresses, extension of service life
