Both galvanized steel pipe and galvanized welded pipe belong to the galvanized steel pipe series. Galvanized steel pipe is a common seamless steel pipe with a galvanized coating. Its zinc coating is generally thinner, and its advantages are higher corrosion resistance and aesthetic appearance, making it suitable for some indoor pipe installations.
Galvanized welded pipe is a product obtained by galvanizing ordinary welded pipe. Its zinc coating is generally thicker, which has stronger corrosion resistance and a longer service life. Galvanized welded pipes are suitable for high-pressure and large-diameter pipelines, such as those in chemical, petrochemical, and power industries, as well as for outdoor pipeline installations.
