The galvanized layer can effectively prevent steel pipes from rusting in humid and corrosive environments, thereby extending the service life of the pipeline. Compared with high-end pipelines such as stainless steel pipes, galvanized pipes have a price advantage and are suitable for engineering projects with limited budgets. Galvanized pipes have good processing performance and can be used for cutting, welding, and other processing operations, which is convenient for construction. Galvanized steel pipes can withstand high pressure and are suitable for drainage systems that require a certain level of pressure.

Galvanized steel drainage pipe, as the name suggests, is a drainage pipe made by galvanizing the surface of ordinary steel pipes. Galvanized steel pipes are mainly divided into two types: cold galvanized steel pipes and hot-dip galvanized steel pipes. Cold galvanized steel pipes have been banned by the country due to their poor corrosion resistance; Hot dip galvanized steel pipes are widely used in building water supply and drainage systems due to their advantages such as uniform coating, strong adhesion, and long service life.

Large diameter drainage steel pipe, as the name suggests, refers to a drainage steel pipe with a larger diameter. According to different materials and manufacturing processes, large-diameter drainage steel pipes can be divided into various types, such as spiral welded pipes, high-frequency welded pipes, seamless steel pipes, etc. Among them, spiral welded pipes play an important role in large-diameter drainage steel pipes due to their high strength and good corrosion resistance.

Large diameter drainage steel pipes are important drainage facilities widely used in urban drainage systems, industrial drainage, sewage treatment, and culverts. Large diameter drainage steel pipes play an important role in modern construction, and their excellent performance and wide range of applications make them an important component of urban drainage systems.
