The manufacturing of galvanized iron wire mesh typically involves several key steps. Initially, high-quality steel or iron wire is sourced, which is then drawn through a series of dies to achieve the desired diameter. After the wire is prepared, it undergoes galvanization, where it is immersed in molten zinc or subjected to a hot-dip galvanization process. This results in a robust protective coat that enhances corrosion resistance.
One of the primary determinants of the friction factor is the roughness of the inner surface of the pipe. Galvanized iron pipes often exhibit a relatively high level of roughness compared to other materials, such as PVC or copper. This rough surface can lead to increased turbulence in the fluid flow, resulting in a higher friction factor. Suppliers need to pay close attention to the manufacturing processes that can influence the surface finish of their pipes. Techniques such as improved galvanization methods or surface treatments could significantly reduce the internal roughness and thereby lower the friction factor.
