Customization Large Diameter Road Drainage Galvanized Metal Culvert Pipe

Galvanized pipes can only be used in neutral or weakly alkaline environments. Once used in acidic environments, they will be corroded and affect their service life. Galvanized pipes need to meet certain conditions during welding, and the welded parts are prone to rusting due to the vaporization and consumption of the zinc layer after welding. Therefore, corresponding anti-corrosion measures should be taken during welding. Galvanized steel drainage pipe is a drainage pipe material with excellent performance and moderate price. It has been widely used in building water supply and drainage systems. However, attention should also be paid to its anti-corrosion performance and welding issues during use.

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.
