Liaocheng virtue Pipe Co., Ltd. is a production and sales: ductile iron pipe, flexible interface cast iron pipes, fittings, large enterprise specialized in ductile pipe fittings, manhole covers casting the production process have reached advanced domestic level. Ductile iron pipe fittings strictly enforce the national standard GB13295-2003 and international standards of ISO2531, EN545 standard, covers the implementation of EN124 standard. At present, our company's pipe products specifications DN80-DN800, also can arrange production according to other standards required by the user. Fittings annual production of two hundred thousand tons have been sold to domestic provinces and Europe, the Middle East, Southeast Asia and other countries and regions. Perfection Since its establishment, has always pursued 'quality first' purpose DN300 ductile iron pipe, mold shop, machine shop, hydraulic workshops, laboratories, workshops and other sand processing and testing equipment, and passed ISO9001 in 2002: 2000 Quality Management System Certification. Ductile iron pipe using a water-cooled metal de la Executed centrifuge mold .Dg100mm less use of closed jacket cooling DN400 ductile iron pipe, Dg150rnm mold all over with rain cooling. Pouring stream need to join calcium alloy plant inlet end for inoculation, after each casting is completed, the need in the mold surface with a thin layer of dry air spray CaSi powder, a centrifuge is the upper and lower halves unit consisting of a closed case ductile iron pipe, mold roller bearing frame mounted on the bottom of the housing, the front end of the mold set with the ring gear, DC motor is mounted on the housing by the end of the direct drive gear mold shell Hugh mold through at both ends are equipped with seals, housing attached to the tip of a mountain of semi-circular cylinder flip sound full rae centrifuge housing with wheels below to reciprocate on an inclined track, centrifuges reciprocating hydraulic system, the pressure is 9.65x105Pa. its speed through the relief valve adjustment, centrifuge cables and cooling water out of the hose is generally fixed on the pole next to the machine, and the other end of the housing, together with the random movement . Centrifuge production specifications are generally fixed DN450 ductile iron pipe, if you want to produce several sizes on a single centrifuge tube, replace the fan package, iron water plant and supporting the mold roller racks. Ductile iron pipe is a cast iron is an alloy of iron, carbon and silicon. Ductile iron is spheroidal graphite form, usually graphite size of 6-7, requires casting on the quality control of the ball grade 1-3 level (ball rate ≥80%), and thus the material itself machinery improved performance has been good, with the nature of iron, steel performance. Annealed ductile iron pipe, the microstructure of ferrite and pearlite, good mechanical properties. DN200 ductile iron pipe | ductile iron pipe | DN500 ductile iron pipe is provided by virtue Liaocheng Industry Co., Ltd. Liaocheng virtue Pipe Co., Ltd. (www.meidegc.com) (www.meidegc.com) (www.mdwfg.com) (www.mdggc.com) strong, credible, Liaocheng in Shandong steel industry has accumulated a a large number of loyal customers.
