Wall thickness detection system and method and storage medium

Abstract

The invention relates to a pipeline detection technology, and discloses a wall thickness detection system and method and a storage medium. The system comprises a first clamping part provided with a first groove, a second clamping part provided with a second groove, a positioning hole, ultrasonic probes, a temperature measuring module, an ultrasonic detector, a circulating pump and a cooling water tank, wherein a cooling channel is formed by the first groove, the second groove and the surface of the pipeline. By means of detachable connection of the first clamping part and the second clamping part, mounting or dismounting can be facilitated, and convenience is improved; cooling liquid injected into the cooling channel can be used as a coupling agent and is used for cooling the ultrasonic probes; a plurality of ultrasonic probes are distributed on the cooling channel to realize multi-point detection; the temperature measuring module monitors the working environment temperature of the ultrasonic probes and is matched with the circulating pump to adjust the flow speed of the cooling liquid in the cooling channel so as to adjust the temperature of the cooling liquid, so that the ultrasonic probe works in a proper temperature range, and the working stability, reliability and detection precision of the ultrasonic probe are effectively improved.

Description

technical field [0001] The invention relates to pipeline detection technology, in particular to a wall thickness detection system, method and storage medium. Background technique [0002] High-temperature pipelines are widely used in petrochemical, coal chemical, nuclear power and other fields. Due to long-term high-temperature and high-pressure working environments, pipelines have failure risks such as wall thickness reduction, corrosion cracking, and perforation leakage. In view of the problem of wall thickness thinning caused by localized corrosion of high-temperature pipelines, the main preventive measure at present is to use high-temperature thickness gauges to regularly measure the thickness of the pipeline at fixed points. Although this method can reduce the occurrence of accidents to a certain extent, it cannot fundamentally Overcome the sudden and occasional characteristics of pipe wall thickness reduction. Due to the large number of pipelines working on the equipm...

In view of the problem of wall thickness thinning caused by localized corrosion of high-temperature pipelines, the main preventive measure at present is to use high-temperature thickness gauges to regularly measure the thickness of the pipeline at fixed points. Although this method can reduce the occurrence of accidents to a certain extent, it cannot fundamentally Overcoming sudden and occasional characteristics of pipe wall thickness reduction

Due to the large number of pipelines working on the equipment site, the wall thickness detection generally adopts a proportional sampling method, which is difficult to ensure full coverage of dangerous parts, multi-point detection cannot be achieved, and the detection efficiency is low; at the same time, ultrasonic probes used in high-temperature detection scenarios The high-temperature couplant is expensive, inconvenient to disassemble and assemble, close contact is required when measuring the wall thickness of high-temperature pipes, the working conditions are poor, and the risk is high
