Remaining strength of Girth welded pipelines due to corrosion defects

Corrosion is an electrochemical process that causes a loss of material in offshore pipelines where the remaining strengths reduce as corrosion advances. Numerous studies have been performed to determine the failure pressures of corroded pipelines, but corrosion on pipelines with additional girth wel...
