ABSTRACT
In recent years, the deep and ultra-deep seas are recognized as the last remaining regions on the planet where oil and natural gas resources are discovered and produced. In order to develop such natural resources in an environmentally safe and cost-effective method, various engineering systems and technologies are being developed. In keeping with this direction of development, there is significant worldwide interest among major offshore structural and system operators in examining the possibility of using high-strength steel for long-distance gas transmission pipelines and risers. In particular, riser pipes using high manganese steel are often made by longitudinal butt welding, In order to make a riser, which is a large pipe structure, it is necessary to do pipework to bend the plate. At this time, welding is required in the longitudinal direction of the riser, and this welding is the longitudinal butt welding. But studies related to the prediction of residual stresses for this are insufficient. In this paper, the residual stress values of longitudinal butt welding of high manganese steel using the hold drilling method were measured. Furthermore, the residual stresses in various directions were calculated using a precise thermal-elastic analysis technique, and comparative verification with the measured values was conducted to see if this method is valid as a residual stress prediction method.
