1. The representation method is different:
Hot-dip galvanized steel pipe generally refers to the standard nominal diameter of the water pipe, which is represented by DN. Hot-dip galvanized steel pipe SC means that the wire is laid through the steel pipe (low-pressure fluid welded steel pipe) SC is an ordinary welded steel pipe, which is equal to the DN of the water major. laying method.
2, the process is different:
The hot-dip galvanized coating is thick, so the anti-corrosion ability is strong. The hot-dip galvanized steel pipe SC is uniform, the surface quality is good, and the thickness of the coating is generally between a few microns to ten microns. Hot-dip galvanizing is a chemical treatment, which is an electrochemical reaction. The hot-dip galvanized steel pipe SC is a physical treatment, only a layer of zinc is brushed on the surface, and there is no galvanized inside at all, so the hot-dip galvanized steel pipe SC is easy to fall off. Hot-dip galvanizing is often used in construction.
The common point of hot-dip galvanized steel pipe and hot-dip galvanized steel pipe SC is that both belong to galvanized steel pipe.
