Different pipe fittings require different pipe materials, and the quality of pipe fittings is directly determined by the quality of pipe materials. Construction engineering, power plants, chemical plants and other industries use such pipe materials.

[0003] Among them, the pipe material widely used is generally rolled from a steel strip. The steel strip is first unwound by an unwinding device and then pulled by a traction wheel to a rolling mill. The steel strip is extruded into a preset cross-sectional shape during the rolling process of multiple rolling mills. After the steel strip is rolled by the rolling mill, it sequentially enters the downstream welding and scraping stations to weld the joints of the pipe material and remove burrs. After the above operation is completed, the pipe material can be cut to the required specification.

[0004] After the burrs are removed, the pipe material needs to be cooled during transportation. The pipe material passes through a cooling channel during transportation. The pipe material is cooled by cooling water in the cooling channel to provide sufficient structural strength for the pipe material to facilitate subsequent processing. However, due to the length of the cooling channel, the existing pipe material cannot pass through the cooling channel directly using the existing guiding structure and its own rigidity, which makes it difficult to connect the pipe material to the roller group of the subsequent station, causing serious adverse effects on the processing of the pipe material, which needs to be improved.
