    Product Advantage

    1.Economical and affordable
    The raw material carbon steel for black steel pipes is rich in resources and the production steps are simple, so the price is relatively low and suitable for various applications.

    2.Rough inner surface
    During the forming process of black steel pipes, the steel pipe blanks will go through processes such as perforation and rolling. These processes will produce a certain roughness on the inner surface of the steel pipe. This will reduce the flow rate of gas or liquid in the pipeline and increase energy consumption and costs. At the same time, this also makes it easy for sediments to form in the pipeline, causing blockage.

    APPLICATION

    Another benefit of black steel pipes is their resistance to corrosion. This is due to the fact that they are coated with a layer of protective oil that helps to prevent rust and other forms of corrosion from forming on the surface of the pipe. This makes them ideal for use in environments where corrosion is a major concern, such as in marine applications or in areas that are exposed to harsh weather conditions.
