The product adopts an advanced casting pipe production process, namely hot-die centrifugal casting of ductile iron pipe. It can be divided into two types: pressure pipe and non-pressure pipe, which are mainly used for water transportation, oil transportation and gas transmission. It has the characteristics of corrosion resistance and long service life (up to 100 years). Its thin wall strength is high, it can save a lot of founding pig iron; high conveying pressure, guarantee safe water supply (gas, oil); simple construction, low construction cost; production cost Low, low energy consumption, high economic efficiency; high technical content of products, with the performance of steel pipes, is the main pipe used for pipeline installation in China's urban construction. The equipment used in the production process is a hydraulic pipe drawing water jet hot mold centrifugal ball cast pipe casting machine, or a water-cooled metal type centrifugal pipe casting machine, using circulating water, no pollution to the water source, and no waste water or waste gas; The use of medium frequency electric furnace saves energy, calms water quality, and has no pollution to the atmosphere and surrounding environment. The product is resistant to bending, vibration and pressure.
