k9 grade ductile iron pipe is ideal for the urban water supply pipe, gas pipe network, set high strength, ductility, and corrosion resistance strong advantages, with the nature of iron, steel performance, is a traditional cast iron pipes and upgrading of ordinary steel products ; water-cooled metal mold centrifugal ductile iron pipe production technology and equipment in 1994 through the national scientific and technological achievements; ductile iron pipe year 1994 was named national new products; DN100-1600mm centrifugal ductile iron pipe technology and equipment through the National Machinery Bureau organization New products, new technology achievement appraisal; epoxy ceramic-lined ductile iron pipe and technological achievements by the Ministry of Construction Organization assessment, the technical indicators have reached the US testing standards, the export volume to fill the gap; centrifugal ductile iron pipe for Chinese urban water supply Association, the China Gas Association recommended products. Centrifugal ductile iron pipe in 2002 won the national quality metallurgical products Gold Award. GB ductile iron pipe drainage ductile iron pipe fittings, ductile iron pipe prices GB, GB k9 ductile iron pipes and drainage pipe fittings, ductile pipe to play excellent mechanical properties and external quality, is the cause of piped water bearer, its ultra- strong bearing capacity, reliable sealing performance, unmatched corrosion protection and water quality assurance system, making nearly perfect Branch piped water, even in complex terrain soil balanced saline, marshes, deserts and high slope, but also ball of energy supply task well done new ductile pipe, ductile iron has some frost resistance in the form of spherical graphite is generally the size of 6-7 grade graphite ductile iron pipes and drainage specifications, requirements on the quality of the casting level control for the 1-3 grade (ball rate ≥80%) drainage ductile iron pipe, ductile iron pipe prices Guigang thus the mechanical properties of the material itself has been good improvement, with the nature of iron, steel performance. Annealed ductile iron pipe, the microstructure of ferrite and pearlite, good mechanical properties. Due to ductile pipe specification generally refers to the inside diameter, PE pipe size generally refers to the outer diameter, Guigang ductile iron pipe under the same price as standard conditions, ductile pipe to achieve greater runoff; from a comprehensive look at the cost of installation and maintenance, ductile pipe has a more favorable price. Drainage ductile iron pipe prices virtue of Industry (certified), Hangzhou, ductile iron pipe drainage is provided by virtue of Liaocheng Industry Co., Ltd. Liaocheng virtue Pipe Co., Ltd.
