      The oil and gas production has grown steadily, and the care with its transportation grid needs to be maintained and expanded. The pipeline used in the transport of gas and oil by-product requires materials with high ...
    • The effect of hydrogen on the fracture toughness of friction-stir welded API 5L X70 pipeline steels 

      Giarola, Joseane; Ávila Díaz, Julián Arnaldo; Cintho, Osvaldo; Cavalcanti Pinto, Haroldo; Oliveira Falcao, Marcelo; Bose Filho, Waldek (2022-08-10)
