[0002] With the rapid development of my country's economic level, steel pipes, as an excellent workpiece, are widely used in industrial fields such as construction and machinery. Due to the harsh working environment, the surface of steel pipes is very easy to oxidize. If the rust or oxide layer on the surface of the steel pipe is not removed in time, it will not only reduce the quality and performance of the steel pipe, but also shorten the service life of the steel pipe. Steel pipe manufacturers need to remove rust on the surface of the steel pipe before flaw detection and painting.
