Equidirectional Umbrella Diameter Changing Mechanism for Ultrasonic Inspection of Seabed Pipelines

Abstract:

Article Preview

Ultrasonic inspection is a key method of inspecting wall thickness flaw of seabed oil pipelines. How to lay out ultrasonic probes to fit for three inner diameter pipelines of Φ195mm, Φ247mm and Φ297mm was analyzed detailed. Diameter changing principle feasibility of ultrasonic inspection adopting 10 parallelogram mechanisms was discussed, and the key parts of structure of equidirection umbrella diameter changing mechanism were analyzed. In the end model machine experiment verified that equidirection umbrella diameter changing technology is feasible.
