China Factory Price Underground Drainage Metal Culvert Pipe/Large Diameter Galvanized Iron Metal Steel Corrugated Pipe

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.

As an important component of urban drainage systems, drainage pipes with large diameters can carry a large amount of rainwater and domestic sewage, ensuring the smooth operation of urban drainage systems. In the industrial production process, large-diameter drainage steel pipes can discharge a large amount of wastewater and waste liquid, ensuring the cleanliness and hygiene of the production environment. In sewage treatment plants, large-diameter drainage steel pipes are used to collect and transport sewage, providing important support for sewage treatment. In underground engineering such as culverts and tunnels, large-diameter drainage steel pipes can ensure unobstructed drainage systems and prevent the occurrence of water accumulation and seepage.

Large diameter drainage steel pipes have a larger inner diameter, which can effectively increase drainage capacity and flow rate, meeting the needs of high flow drainage. Made of high-quality steel, it has high strength and rigidity, and can withstand large pressures and loads, ensuring the stable operation of the drainage system. After anti-corrosion treatment (such as coating with epoxy coal tar, hot-dip galvanizing, etc.), it can effectively resist corrosion and chemical erosion, and extend its service life. Large diameter drainage steel pipes are usually installed using spiral structures or flange connections, with tight connections and convenient installation.
