Ductile iron pipe scope for gas, water ductile pipe, such as water pipe network transformation, municipal pipe network transformation, industrial water and other liquids transported (wine) delivery. Flexible interface cast iron drainage pipe is a gravity sewage pipe, widely used in high-rise buildings of sewage, rainwater drainage and ventilation. Ductile iron pipe with high quality low sulfur, low phosphorus pig iron, equipped with seed manganese, silicon and other rare materials, cast iron water through a special inoculation, the grain structure refinement, has greatly improved the tensile strength and impact of straight pipe centrifugal casting process performance, high-speed rotation of the product more compact organization. Corrosion-resistant, high strength water will no noise in use for more than 50 years of easy maintenance, easy installation and fast construction can be cut. Ductile iron pipe is mainly known as ductile iron pipe, which has the nature of iron, ductile pipe k9 excellent performance, corrosion resistance of steel, ductility, good sealing effect, easy to install, mainly for municipal, industrial and mining water supply, transport gas, oil and so on. Is the preferred water supply pipe, with a high cost. Compared with PE pipe, from the installation time, ductile pipe is easier than PE pipe installation fast and better internal and external bearing pressure after installation; tightness and corrosion resistance from the point of view, ductile pipe tightness better after installation, but also through a variety of corrosion means to improve the corrosion resistance; from the hydraulic performance point of view, due to ductile pipe specification generally refers to the inside diameter, PE pipe size generally refers to the outer diameter of dn250 ductile pipe, because ductile pipe factory under the same standard conditions, the ductile pipe to achieve more large runoff; from a comprehensive look at the cost of installation and maintenance, ductile pipe has a more favorable price. The main components of ductile iron pipe with carbon, silicon, manganese, sulfur, phosphorus and magnesium. The inner wall of spray zinc, anti-corrosion materials, such as cement mortar. dn250 ductile pipe, ductile pipe manufacturer (certified), ductile pipe is provided by virtue of Liaocheng Industry Co., Ltd. Liaocheng virtue Pipe Co., Ltd. (www.meidegc.com) Shandong Liaocheng, steel leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Industry leaders in the United States and Germany with the staff warmly welcome all inquiries negotiations to create the virtues pipe industry a better future.
