DN1200/1800 large-diameter spiral steel pipe is a large-diameter steel pipe used for transporting fluids or structural support. It has the following characteristics:
DN1200 and DN1800 indicate that the nominal diameter of the steel pipe is 1200 mm and 1800 mm respectively, which are suitable for occasions requiring large flow transmission.
The steel pipe adopts spiral welding process, and the welds are distributed in a spiral shape, which has high welding quality and strength.
Diverse materials: Different materials can be selected according to different use environments and requirements, such as Q235B, Q345, Q355 and other low-carbon alloy structural steels.
Anti-corrosion treatment: In order to improve the corrosion resistance of steel pipes, internal and external anti-corrosion treatments can be carried out, such as 3PE anti-corrosion, IPN8710 anti-corrosion, etc.
DN1200/1800 large-diameter spiral steel pipe is widely used in pipeline systems in petroleum, natural gas, chemical industry, electric power, urban public utilities and other industries to transport fluids or serve as structural support.
