The disclosed embodiments include in-line inspection devices, methods to perform in-line inspections of pipeline and protective casings, and methods to determine anomalies of pipeline and protective casings. The method includes deploying an in-line inspection device in a section of a pipeline enclosed by a protective casing. While the in-line inspection device is traveling along the pipeline, the method also includes transmitting, at a frequency, a transmitted signal toward the protective casing; and detecting a scattered signal scattered by the protective casing. The method further includes detecting a scattered signal scattered by the protective casing. The method further includes locating an anomaly of the protective casing based on the scattered signal.

An apparatus includes a body and a fluid sampling conduit disposed within the body. The body is configured to be disposed within a pipe flowing a fluid. The fluid sampling conduit is configured to obtain a sample of the fluid flowing in the pipe. The apparatus includes an odometer wheel coupled to the body and an elastomeric ring surrounding at least a portion of the body. The elastomeric ring is configured to remove material disposed on an inner wall of the pipe as the apparatus travels through the pipe. The apparatus includes a solid sampling subsystem coupled to an external to the body. The solid sampling subsystem includes a capsule, an inlet valve, and a tubing. The inlet valve, when opened, allows at least a portion of the material removed from an inner wall of the pipe to flow through the tubing and into the capsule.
