Pipeline wrinkling is a localized buckling deformation where folds or wrinkles form in the pipe wall — typically caused by excessive bending, overpressure events, or installation defects.

Pipeline wrinkling is a localized buckling deformation where folds or wrinkles form in the pipe wall — typically caused by excessive bending, overpressure events, or installation defects. Wrinkling reduces effective wall thickness, creates stress concentrations, and can progress to leaks or rupture if left unaddressed.

Wrinkling commonly occurs in pipeline bends, areas of ground movement, or sections subjected to axial compression. Detection requires geometry inspection capable of identifying small-scale wall deformations.

EMPIT’s CMI technology detects pipeline wrinkling and other geometry anomalies through high-resolution aboveground magnetic field analysis — providing precise deformation data without excavation. Combined with bending strain and 3D position data, CMI delivers a comprehensive geometric integrity assessment for at-risk pipeline sections.
