The Effects of Operational, Testing, and Material Characterizations on the Change in Yield Strength From Plate to Pipe

The rapid growth of energy consumption has increased the demand of pipelines for the transportation of oil and gas. UOE is one common technique for manufacturing pipes, and its pipe products are evaluated by tensile tests after cutting and flattening the specimen. The mechanical performance of the pipe sample has a direct influence on their application and a significant economic impact on manufacturers. There is often a change in the yield...
