Shaanxi cast iron manhole covers, Shunxiang ductile pipe, cast iron manhole covers are Liaocheng Shunxiang Supply Building Materials Co. (www.lcsxjc.com) 2013 launch of Liaocheng been newly upgraded Building Materials Co., Ltd. Main Shunxiang: cast iron manhole covers ductile iron pipe prices, flexible interface cast iron pipes, fittings, large enterprise specialized in ductile pipe fittings, cast covers aspects of the production process have reached advanced domestic level. Ductile iron pipe fittings strictly enforced GB GB13295-2003 and international standards ISO2531, EN545 standard, covers the implementation of EN124 standards. Currently my company's pipe product specifications DN80-DN800, also can arrange production according to other standards required by the user. Tube million tons annual output of two hundred, have been sold to domestic provinces and Europe, Middle East, Southeast Asia and other countries and regions. Since its establishment perfect cast iron manhole covers, has always pursued "quality first" purpose, mold shop, machine shop, hydraulic workshops, laboratories, workshops and other sand processing and testing equipment, and in 2002 passed the ISO9001: 2000 Quality Management System certification. Now I have a lot of ductile iron pipe stock, will be price, wholesale and retail fashion cast iron manhole cover manufacturer, to provide you with fast quality service, welcome new and old customers to negotiate, Power Conference. Liaocheng Shunxiang Building Materials Co. is a ductile cast iron is an alloy of iron, carbon and silicon. Ductile iron is spheroidal graphite cast iron manhole cover in the form of supply, the general size of 6-7 grade graphite, requiring Pipes on the quality control of the ball for the 1-3 grade level (ball rate ≥ 80%), and thus the material Mechanical properties of its own to get a better improvement, with the nature of iron, steel properties. Annealed ductile iron pipe, the microstructure of ferrite and pearlite, good mechanical properties.
