CORROSION PROCESSES IN METAL AND WELDED CONNECTIONS OF THE MAIN GAS PIPELINES

Basiev K.D., Tibilov V.I., Bigulaev A.A., Alborov A.D., Tibilov O.V.

The processes of development of stress-corrosive cracks in steels and welded joints of gas-main pipelines are being considered. The technique and samples to assess the tendency of steels to the nucleation of stress corrosive cracks is being developed. Analysis of the stress-corrosive cracks obtained in laboratory environment on X-46 and X-70 steels allows studying the kinetics of their  development and determining optimal technologies that improve the quality of pipe sheet products. The studies were conducted in the North-Caucasian Institute of Mining and Metallurgy and  «Stroygazconsulting” LLC
