In the present work, compound 3´-(2,6-dimethoxybenzoyl)-benzyl 2,6-dimethoxybenzoate (RM4) was evaluated for its ability as a corrosion inhibitor in 3% chloride medium and using an API 5L X70 steel working electrode. The electrochemical system by techniques such polarization curves (CP) impedance spectroscopy (EIS), finding through values obtained that efficiency of at 50 ppm reached 73.2% agai...

In this paper, buckling of cylindrical grooved shells under axial load has been examined by theoretical and experimental methods. The shell is made of USA/API – X42 5L steel standards. This material is one of the most common materials used in gas, oil and petrochemical industries. The effect of spiral grooves on cylindrical shell was analyzed, and the results obtained from the Abaqus software w...

The ductile fracture arrest may present supplementary requirement for selection of base material for most demanding steel welded structures. The most representative one with such requirement are gas pipelines. Therefore to ensure that the pipeline materials has adequate toughness to arrest a ductile fracture, the pipe material must be designed and tested in accordance with the specific procedur...
