Austenitic stainless pipe inner wall oxide skin nondestructive testing device

Abstract

The present invention discloses an austenitic stainless pipe inner wall oxide skin nondestructive testing device comprising a probe, an electromagnetic detector and a data processor which are sequentially electrically connected; the probe comprises a casing, a permanent magnet, an induction coil, an installation part and two scan parts, induction coil winds the permanent magnet and is installed in the casing together with the permanent magnet, the installation part is embedded in the casing, one ends of the two scan parts are respectively movably connected with the same end of the installation part, when the probe works, an included angle between the two scan parts is adjusted to detect pipes with different specifications. Compared with the prior art, the detection device has the advantages of compact structure, fast detection speed and accurate and reliable detection result, the probe scans a to-be-detected pipe by the scan parts, and does not contact with the to-be-detected pipe, the probe abrasion in the long term detection can be avoided, the service life of the probe is improved, the use cost is reduced, the included angle between the two scan parts is adjustable, the austenitic stainless pipe inner wall oxide skin nondestructive testing device is flexible in use, and is suitable for various specifications of pipelines; therefore, the application prospect is very wide.

Description

technical field [0001] The invention relates to a detection device, in particular to a non-destructive detection device for oxide skin on the inner wall of an austenitic stainless steel pipe, belonging to the technical field of non-destructive detection. Background technique [0002] Non-destructive testing technology, that is, non-destructive testing technology, is a method used to obtain physical and chemical information related to the quality of the test material, such as content, properties or components, without destroying the original state and chemical properties of the test material. Detection method.

Problems solved by technology

This kind of detection probe can detect the presence or absence of oxide skin in the tube, but it cannot accurately reflect the spatial appearance of the oxide scale accumulation in the tube; and the detection probe is large in size, which is not conducive to working in a narrow space, and the shape of the yoke is complicated and difficult to manufacture. And the manufacturing cost is high; in addition, the shape and size of the detection probe are fixed and cannot be adjusted, so it is not suitable for the detection of pipes with different specifications and diameters, and the applicable surface is small
