Problems solved by technology

On November 22, 2013, a particularly serious explosion accident occurred in Sinopec Qingdao Donghuang Oil Pipeline. Crude oil leaked from the pipeline entered the municipal drainage culvert, and the oil and gas accumulated in the culvert in the closed space of the journey met sparks and exploded, killing 62 people and injuring 136. Direct economic loss of 750 million yuan
However, this kind of probe and fixing device cannot adjust the number and installation position of the probes, and the guided wave mode cannot be selected according to the type of pipeline, and a set of devices can only be used for the detection of pipelines with the same diameter. In the work tasks of various pipeline detection the cost is too high

Abstract

The present invention relates to the technical field of non-destructive detection, and in particular relates to a pipeline ultrasonic longitudinal guided wave flexible array detection probe apparatus including a number of probe units, a chain unit for fixing the probe units into an annular array, and a fastener for fitting the detecting ends of the probe units on a to-be-tested pipe. The probe units of the pipeline ultrasonic longitudinal guided wave flexible array detection probe apparatus are compact in structure and good in mechanical coupling effect, and the pipeline ultrasonic longitudinal guided wave flexible array detection probe apparatus has rapid loading and unloading, and modular and flexible features, and can achieve adjustment of jig length, probe array element specification, probe array element number, and a number of parameters of probe incidence angle.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a pipeline ultrasonic longitudinal guided wave flexible array detection probe device. Background technique [0002] As an efficient and reliable fluid working fluid transportation component, pipelines are more and more widely used in modern petrochemical, power generation, transportation and other fields. According to the latest "World Documentary Yearbook" statistics, in 2013, the number of oil and gas transportation pipelines in operation in the world has reached 3.56 million kilometers, and the length of China's oil and gas transportation pipelines has also exceeded 134,000 kilometers, bearing 70% of crude oil and 99% of natural gas. transport tasks. [0003] At present, many pipelines are faced with typical damages such as corrosion and wear, which lead to the thinning of the pipeline wall and the decline of the mechanical strength, resulting in pipeline leak...
