High-quality, smart pig dent inspection complies with rules for gas, liquid lines

ROSEN has developed an innovative high-resolution in-line inspection (ILI) technology for the characterization and sizing of dents. Introducing a high-quality in-line inspection process for dents and mechanical damage can provide the basis information like the geometric data of dents and stress riser to start a managed integrity process for the inspected line. The performance of a geometry inspection configuration for dents can be estimated by using an analytical model. According to this model, the ROSEN Electronic Geometry Pig (EGP) tool achieves a high probability of detection although equipped with only eight channels around the circumference.
