The answer is yes, DN50 galvanized steel pipe is widely used in residential, commercial, and industrial water supply pipelines. The zinc coating provides a protective barrier against corrosion, extending service life compared to ordinary carbon steel pipe.

However, when used for potable water, buyers should pay attention to the pipe’s zinc coating thickness and quality certification (such as ISO, ASTM, or EN standards). A proper hot-dip galvanized coating ensures better resistance to rust and contamination.

DN50 galvanized steel pipe is a reliable choice for water supply systems, provided it meets national standards and has sufficient zinc coating thickness.
