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...

Pipe elbows (bends) are considered critical pressurized components in the piping systems and pipelines due to their stress intensification effect of bend curvature. They prone hence more exposed different corrosion failure modes than straight pipes. Late detection such elbow damages can lead dangerous emergency situations which cause environmental disasters, pollution, substantial consumer loss...
