K9 Shandong Ductile Iron Pipe

The nature of centrifugal ductile iron pipe has iron, high performance, corrosion resistance of steel, ductility, good sealing effect, easy to install, mainly ductile iron pipe used in municipal, industrial and mining water, gas, oil and the like. 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 quick and better bearing pressure inside and outside the installation; from tightness and corrosion resistance point of view, ductile pipe tightness better after installation, but also through a variety of means to improve the corrosion resistance of corrosion; from the hydraulic performance point of view, due to ductile pipe specification generally refers to the inner diameter, PE pipe size generally refers to the outer diameter, the same size as under conditions of ductile pipe can achieve greater runoff; from Comprehensive installation and maintenance costs, the ductile pipe has a more favorable price. The main components of ductile iron pipe carbon, silicon, manganese, sulfur, phosphorus and magnesium. Inner wall spray zinc, cement mortar anticorrosive materials. Ductile Iron low cost makes this material more popular, casting more efficient, but also less ductile iron machining costs. Ductile iron pipe is a combination of magnesium or magnesium rare silky agent before pouring molten iron in the graphite ball, stress concentration decreased, so that the pipe has a high strength, high elongation, impact resistance, corrosion resistance, good sealing Advantages; inner wall of cement mortar lining, improve water environment of the pipeline to improve the water supply capacity, reducing energy consumption; nozzle with flexible interface, and the pipe itself has a large elongation (> 10%), the flexible pipe better, in buried pipelines to be working with the soil around the pipe joint, improve the stress state of the pipe, thereby improving the reliability of the network operation. Therefore, China's water industry generally ductile iron pipe as the competent material. Buying Shandong k9 ductile iron pipes to find Qingdao Jinrui Pipe Co., Ltd. www.qdjrgy.com, Tel: 13697654893
