ABSTRACT:
This invention relates to non-destructive testing of metallic pipelines using a pig having a novel way of mounting sensors for detecting any defect in the pipe wall. The sensors are mounted around the outer edge of an elastomeric cup which is rigidly fixed to the pig body. The sensors are maintained in contact with the internal surface of the pipe by a spring member which urges the sensors radially outward from the pig body.
