DN1200-1600mm centrifugal ductile iron pipe technology and equipment through the National Machinery Bureau of new products and new technology achievement appraisal; DN1800-2600mm large diameter ductile iron pipe project was listed as a national technology industry demonstration projects; epoxy ceramic-lined ductile cast 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; GB ductile iron pipe, ductile iron pipe prices GB, GB k9 ductile iron pipe, ductile pipe to play outstanding mechanical properties and external quality cast iron drainage pipe connected to piped water is the cause of the bearer, its superior bearing capacity, reliable sealing performance, unmatched corrosion protection and water quality assurance system, so that the water supply pipeline near Branch perfect, even in complex terrain saline soils, wetlands, deserts, high slope and balanced cast iron drainage pipe standards, but also to supply the task well done new ductile pipe, ductile iron has some frost resistance is spherical graphite form, the general size of 6-7 grade graphite, requires casting the quality control of the ball for 1-3 grade level (ball rate ≥80%), ductile iron pipe prices Guigang mechanical properties of the material itself and thus get a 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 cast iron drainage pipes, ductile iron pipe prices Guigang specifications under the same conditions because, ductile pipe to achieve greater runoff; from a comprehensive look at the cost of installation and maintenance, ductile pipe has a more favorable price. Cast iron drainage pipe fittings | virtues of Industry (certified) | Liaocheng cast iron drainage pipe is provided by virtue of Liaocheng Industry Co., Ltd. Liaocheng virtue Pipe Co., Ltd. (www.meidegc.com) (www.meidegc.com) (www.mdwfg.com) (www.mdggc.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.
