Multifunctional ultrasonic phased array pipeline circumferential weld detection equipment

Abstract

The invention provides multifunctional ultrasonic phased array pipeline circumferential weld detection equipment which comprises a main body, a magnetic pressure wheel mechanism, an auxiliary support, a fastening device, a left flaw detection probe bracket, a right flaw detection probe bracket, a left flaw detection probe and a right flaw detection probe, wherein the main body comprises a base, a first slide bar, a second slide bar, a slide bar jackscrew, a left slide bar connecting rack, a right slide bar connecting rack, magnetic wheels and an axle; the fastening device is used for fastening the main body on a pipeline to-be-detected; the magnetic pressure wheel mechanism is arranged between the first slide bar and the second slide bar; the auxiliary support is connected with the first slide bar and the second slide bar of the main body; the flaw detection probe brackets are connected with the flaw detection probes and help the flaw detection probes to detect a weld joint of the pipeline to be detected. The equipment can rotate around the flaw detection pipeline smoothly during pipeline circumferential weld detection, thereby preventing impact of accidental conditions such as vibration on the detection effect, enlarging the application range of the equipment, and improving the flaw detection sensitivity and the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of pipeline flaw detection, in particular to a multifunctional ultrasonic phased array pipeline girth weld detection device. Background technique [0002] At present, in the installation and construction of refining and chemical equipment, the amount of non-destructive testing of butt girth welds of large thick-walled and large-diameter pressure pipes is increasing; using A-type pulse ultrasonic testing, the defect display is not intuitive, and the shape of the defect cannot be displayed. And defect measurement is greatly affected by human factors, and the repeatability of defect detection and evaluation is poor; X-ray detection is more and more difficult or even impossible to detect (insufficient penetration); gamma-ray detection is difficult for safety protection (some places are not allowed to use), detection The time is long, the detection time is limited, and the half-life is short. Therefore, not only ...
