Oil pipe online cleaning and flaw detecting device

Abstract

The utility model relates to the technical field of oil pipe flaw detection, in particular to an oil pipe online cleaning flaw detection device. The oil pipe online cleaning and flaw detecting device comprises an erecting ring, a rotationally-connected abutting pipe with the L-shaped section is installed on the lower ring face of the erecting ring, an annular air bag is installed in the abutting pipe, and a plurality of annular protruding scraping pieces which are distributed at equal intervals up and down are fixedly installed on the inner ring wall of the annular air bag; the inner diameters of the blade faces of the annular protruding scraping pieces are sequentially decreased from bottom to top. The oil pipe on-line cleaning flaw detection device is provided with a plurality of annular protruding scraping pieces, so that the cleanliness of oil dirt hanging and falling of the oil pipe can be greatly improved, and the inner diameters of the blade faces of the annular protruding scraping pieces are sequentially decreased from bottom to top, so that the abutting force of the annular protruding scraping pieces on the annular air bag and the oil pipe is decreased from top to bottom. Therefore, each annular raised scraping blade is prevented from being strongly abraded.
