Abstract

The invention provides an ultrasonic detection device and a detection method for an in-service pipeline or a pressure vessel. The device comprises a track assembly, a detection trolley, a longitudinaldriving assembly and a detection controller, wherein the track assembly comprises a flexible track and an auxiliary positioning part for positioning the flexible track on a to-be-detected wall surface; the detection trolley comprises a trolley main body, a transverse driving assembly and a phased array detection probe assembly, the phased array detection probe assembly is fixed with the trolley main body, and the trolley main body is arranged on the flexible track and is driven by the transverse driving assembly to move along the flexible track; the longitudinal driving assembly is connectedwith the flexible track and drives the flexible track to move along the to-be-detected wall surface; and the detection controller comprises a probe excitation unit connected with a phased array probein the phased array detection probe assembly, and a movement control unit connected with the longitudinal driving assembly and the transverse driving assembly. The device is suitable for detection ofvarious external diameters and various wall surfaces.

Description

technical field [0001] The invention relates to the technical field of detection of in-service pipelines or pressure vessels, in particular to an ultrasonic detection device and detection method for in-service pipelines or pressure vessels. Background technique [0002] In recent years, with the rapid development of my country's national economy, the demand for energy is also increasing, and at the same time, it has driven the development of a large number of petrochemical enterprises. Whether these industries are used for raw material storage, transportation or industrial process of chemical smelting, a large number of pipelines and pressure vessels are used. The safe operation of these pipelines and pressure vessels is critical. In particular, pipelines or pressure vessels are prone to metal fatigue during long-term pressurized gas transmission and pressure relief, and many pipelines or pressure vessels are placed on the ground, and there are no underground facilities for...
