GB ductile iron pipe, ductile iron pipe prices GB, GB k9 ductile iron pipe, ductile pipe to function as excellent mechanical properties and external quality, is the cause of piped water bearer, its superior bearing capacity, reliable seal performance ductile iron pipe prices, unmatched corrosion protection and water quality assurance system, so nearly perfect division piped water, even in complex terrain balanced saline soils, wetlands, slope and high desert, but also the water supply task well done The new ductile pipe, ductile iron has some frost resistance in the form of spherical graphite is generally graphite size of 6-7, requires casting on the quality control of the ball grade 1-3 level (the ball rate ≥80%), Guigang ductile iron pipe prices thus 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 inner diameter, PE pipe size generally refers to the outer diameter, Guigang ductile iron pipe prices because under the same standard conditions, the ductile pipe can achieve greater runoff; from a comprehensive look at the cost of installation and maintenance 700 ductile iron pipe prices, ductile pipe has a more favorable price. Ductile iron pipe using a water-cooled metal de la Executed centrifuge mold .Dg100mm less use of closed jacket cooling, 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 closed housing unit consisting of a wheel frame supporting the mold 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 off ends are equipped by the mold at the seal, the front end of the housing is mounted a turning cylinder semicircular mountains full sound rae centrifuge housing below with wheels to reciprocate on an inclined track, reciprocating centrifuge using hydraulic equipment, pressure 9.65x105Pa. its speed through the relief valve adjustment, centrifuge cables and cooling water out of the hose is generally fixed to a pillar beside the 300 machine ductile iron pipe prices, the other end of the housing, random move together. Centrifuge production specifications are generally fixed, 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. Company annual production and operation of ductile iron pipes, fittings, "is now stock amounted to" 20000 "tons more than a hundred kinds of specifications. At the same time there are enterprises covering 2000m2 indoor warehouse, 3000m2 outdoor library, technology products according to user requirements and relevant standards organizations operating ductile cast iron pipes. The company is specialized in the production of flexible cast pipe fittings, pipes and pipe fittings to private enterprise. was formerly foundry 500 ductile iron pipe prices, has twenty years of history. The main production of flexible cast iron pipe and related fittings, and a variety of radiators. The company's products through the relevant quality inspection departments qualified for many years to high-quality products and personalized service, Ying won a lot of customer recognition. "high product quality, innovation and Benefit" business purpose We always pursue "first-class quality, first-class service, first-class brand, first-class benefits" pursue "strict, precise, high, that" the management principles. Our company produces ductile iron pipe capable of withstanding high internal pressure, during the pressure test, the test pressure than the international dimension and the European dimension are higher than 1MPa. ductile iron pipe also has good resistance to external pressure, can reduce tube bed and the protective layer production requirements, so economical and reliable pipeline ; In addition, zinc spray, spray paint asphalt, lined with cement and other measures to ensure that the casting of the inner and outer anti-corrosive zinc spray my company's compliance with ISO8179 quality delineation, per square meter of the pipe minimum amount of spraying zinc. 130g, the thickness of asphalt paint is not less than 70μm, cement mortar lining comply with ISO4179 quality delineation and ensure robust chamber mortar, smooth, strong adhesion. ductile iron pipe prices, ductile iron pipe prices, Liaocheng virtue by the virtue of Industry Industry Limited.
