Basic Info

Product Description

Galvanized welded pipe is a welded steel pipe that has been galvanized. Its galvanized layer is generally thicker, with stronger corrosion resistance and longer service life. Galvanized steel pipes are divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanized welded pipes have thick layers and rough surfaces; electro-galvanized welded pipes have low costs and rough surfaces. Oxygen-blowing galvanized welded pipes: used for steelmaking oxygen-blowing pipes, generally small-diameter welded steel pipes. Galvanized welded pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, etc. In addition, galvanized welded pipes are also suitable for some high-pressure and large-diameter pipelines, such as chemical, petrochemical, electric power and other industrial fields, as well as some outdoor pipeline installations.
