In industrial applications, there are many types of steel pipes. Among them, spiral steel pipes and stainless steel pipes are two common types. They play an important role in various industrial fields, and their surface processing differences are key factors affecting their performance and application.
First, let's look at the surface treatment of stainless steel pipes. The surface treatment of stainless steel pipes usually includes two processes: hot rolling and cold rolling. The hot-rolled steel pipes will perform heat treatment and pickling treatment. This process is usually used in industrial slot tanks, chemical industrial devices, etc. Its thickness is thick, generally between 2.0mm-8.0mm. After cold rolling stainless steel pipes, the heat treatment and pickling will be performed again to make the surface show silver -white luster. This processing method makes the material softer, suitable for deep pressure processing, such as car components and water pipes.
On the other hand, the surface treatment of the spiral steel pipe mainly relies on tools such as steel wire brushes to polish the appearance of the steel to remove loose oxide, rust, and welded slag. This processing method will reach different surface levels as needed. For example, the rust removal of the hand can reach the SA2 level, and the power tool removal can reach the SA3 level. If a strong iron oxide skin is attached to the appearance of the steel, a more powerful treatment method is needed.
In the surface treatment of the spiral steel pipe, spraying (throwing) shooting rust is an important way. This method can not only expand the physical adsorption effect of the tube appearance, but also enhance the mechanical adhesion effect of the anticorrosive layer and the tube appearance. Therefore, spraying (throwing) rust removal is the ideal method of rust removal of pipeline anticorrosion. Generally speaking, the spray (sand) rust removal is mainly used for the disposal of the inner and outer surface of the tube, and the rust of shot blasting (sand) is mainly used for the disposal of the tube appearance.
As for the surface shape of the spiral steel pipe, it also has its own uniqueness. For example, the hairy hairline, continuously grinding the grinding pattern products with appropriate granularity polishing sasal bands, is mainly used in the fields of building decoration, elevators, buildings, panels and other fields. In addition, the bright surface is a product obtained by the lighting and being flat after the cold rolling. Its surface gloss is excellent and has a high reflectivity. Materials, etc.
In summary, the surface processing of spiral steel pipes and stainless steel pipes has obvious differences in processing methods, equipment, and purposes. These differences make them each have unique performance and use, which can meet the needs of different fields. In practical applications, we need to choose the appropriate steel pipe types and surface treatment methods according to specific needs and conditions.
