Probe system for ultrasonic guided wave detection of marine pipeline and design method thereof

Abstract

The invention relates to a probe system for an ultrasonic guided wave detection of a marine pipeline and a design method thereof. The probe system provided by the invention comprises multiple probe system unit modules, quick-locking mechanisms, connecting shafts and air sacs, wherein the air sacs are contained in the probe system unit modules; the probe system unit modules are connected through the connecting shafts; the two adjacent probe system unit modules can rotate around the connecting shafts to form a flexible structure; the probe system unit modules which are connected into a whole encircle the outside surface circumference of the detected marine pipeline; the two probe system unit modules at the head and the tail are connected and clamped through the quick-locking mechanisms so as to be annularly positioned at the outside surface circumference of the detected marine pipeline; and the probe system unit modules are sealed by a waterproof material. In the design method provided by the invention, the probe rings and probe ring clamp systems of probe systems are of a modular structure; the probe rings comprise the multiple probe system unit modules; the probe ring clamp systems comprise clamp modules and are mutually connected through the connecting shafts; and the heads and tails of the probe ring clamp systems are locked through the quick-locking mechanism to form the probe system with certain flexibility.

Description

technical field [0001] The invention belongs to the field of nondestructive testing of pipelines, and relates to a probe system and a design method thereof for ultrasonic guided wave testing of marine pipelines. Background technique [0002] In the development of offshore oil and gas resources, pipelines are the main form of oil and gas transportation and the lifeline of offshore oil and gas field development and transportation. Pipeline corrosion is a major safety hazard in offshore oil and gas production. If these potential dangers cannot be discovered in time during pipeline operation, oil and gas leakage may occur, pipeline accidents may occur, and cause major economic losses and negative social impacts. Therefore, in order to ensure the safe operation of marine pipelines during their service and prolong their service life, the safety inspection of in-service pipelines has become an important research topic for countries all over the world. [0003] With the development...

AI Technical Summary

Problems solved by technology

The above two types of flexible probe systems are relatively complicated to install and are not suitable for marine pipeline inspection, and the flexible fixtures are for pipes with a specific outer diameter, which also limits the overall scalability of the flexible probe system
