Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 ,Such as figure 2 As shown, a probe system for ultrasonic guided wave inspection of marine pipelines provided by the present invention is composed of a probe system unit module 1 , a quick lock mechanism 2 , a connecting shaft 3 and an air bag 5 . In this embodiment, an ocean pipeline 4 with an outer diameter of eight inches is taken as an example. A total of twenty-four probe system unit modules 1 are arranged on the circumference of the ocean pipeline 4, and each probe system unit module 1 is connected by a connecting shaft 3, and Two adjacent probe system unit modules 1 can rotate around the connecting shaft 3 to form a flexible structure. Each probe system unit module 1 that is connected into one circle is wrapped around the outer surface of the ocean pipeline 4 to be tested, and the two probe system unit modules 1 at th...

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...
