Are you worrying your black steel pipe in applications

In the recent years, people prefer black steel pipe to convey water and gas in rural and urban areas for a long time. Specifically, in some practical application sectors, black steel pipe’s strength performance makes it ideal for transporting water and gas in rural and urban areas, as well as widely used for conduits to protect electrical wiring. In oil & petroleum industries people usually use round steel pipe for moving large quantities of oil through remote areas. However, like any metal products, black steel pipe is prone to corrosion and damages in applications over time without any maintenance. Once people would be aware of such a potential risk of black steel pipe in use, there are many possible solutions for you to protect your black steel pipe from any corrosion and damages in advance.

First of all, before you would make a decision on your desired black steel pipe, a good steel pipe manufacturer would become very important for you to avoid many potential risks in your next projects. As a rule, the reliable steel pipe manufacturer will have careful inspections for surface imperfections and surface alterations caused during fabrication processing in a mill, (e.g. welding). This is because certain surface imperfections introduced during the original processing of the steel may not be detrimental to the performance of a coating in service particularly for structures in relatively low risk environment categories. However, as per the specific requirements of the structure, it may be necessary to remove general surface imperfections on welds and cut edges to produce an acceptable surface condition for painting in certain cases.

In addition, surface preparation is the essential first stage treatment of a substrate for cold rolled steel pipes before the application of any coating. The performance of a coating is significantly influenced by its ability to adhere properly to the substrate material. It is generally well established that correct surface preparation is the most important factor affecting the total success of surface treatment. The presence of even small amounts of surface contaminants, oil, grease, oxides and etc. can physically impair and reduce coating adhesion to the substrate. Alternatively, metal coatings applied by thermal spraying require a coarse surface profile to maximize the coating bond which is principally by mechanical keying. Organic paint coatings adhere to the surface mainly by polar adhesion which is aided by mechanical adhesion which is especially important for thick coating films.
