Residual stress measurement inside a welded pipe

The inner diameter of pipes is a critical location for design and performance assessment. Corrosion, fatigue, and stress corrosion cracking often attack the pipe inner diameter, which can lead to leakage and possible failure of the system. Tensile residual stresses in welded pipe joints can have a significant impact on structural integrity and performance because they accelerate crack initiation and growth. In engineering design, understanding the magnitude and distribution of residual stresses on the pipe inner diameter allows accurate structural assessment and planning for inspection. Measuring residual stress on the pipe inner diameter is challenging and provided a unique opportunity to express our commitment to innovation.
