[0002] Welded pipe is welded steel pipe, which is made of steel plate or strip after curling and welding. The production process of welded pipe is simple, with high production efficiency, many varieties and specifications, and low equipment investment. After the welded pipe is processed into a finished product through multiple processes, it is necessary to apply protective oil on the inner and outer walls of the welded pipe before packaging in the warehouse to prevent the welded pipe from being oxidized and rusted during placement and storage, thereby affecting the quality of the steel pipe. At present, the inner wall of the welded pipe is usually oiled by lifting the whole welded pipe into an oil pool and immersing it in the protective oil in the oil pool. After soaking for a certain period of time, it is lifted up, and the protective oil in the oil pool adheres to the inner wall of the welded pipe, so as to achieve the purpose of oiling the inner wall.

[0003] The existing oil spraying device for the inner wall of the welded pipe usually cannot spray the protective oil evenly on the inner wall of the welded pipe, resulting in poor oiling quality. Therefore, we propose an oil spraying device for the inner wall of the welded pipe. Utility Model Content
