The new diagnostic electrochemical features for the limited technical state of a pipe with macrodelamination was proposed, a reaching of it creates a danger of anmicrodefectegress on external surface. The expertise of the effectiveness of the gas compressor station elbow defectiveness for two type sizes and the liner above ground part of the 30 years operated in the highlandsmain gas pipeline was carried out. The macrodelamination in a wall of two pipes of gas pipeline like “pipe in pipe” were revealed, which were restricted by neighbour ring welds. The monitoring of the revealed delamination spread during 3.5 years was passed over. The practical recommendations regarding an evaluation of workability and residual lifetime od pipes with macrodelamination were developed  Product Description popup.authors Voloshyn Vitaliy А.
