Ductile iron pipe, ductile iron pipe applications has iron, ductile iron pipe essence, performance, corrosion resistance of steel, ductility is good, easy to install, mainly used for municipal, industrial and mining water, gas, oil and other ductile iron pipe production technology since the 1990s, introduced from abroad, after digestion, absorption, improvement and innovation, our ductile iron pipe production is now higher specification, ductile iron pipe, to meet a variety of customer needs, product long service life, environmental health, water pipe is much preferred. Liaocheng virtue Pipe Co., Ltd. The main products of ductile iron pipe using today's advanced technology, in strict accordance with ISO2531 ISO production and testing, to produce cement-lined, lined with epoxy resin, ceramic liner, outer spray ring epoxy resin, self-anchored pipe and other specifications models of ductile iron pipe. Products with good toughness, corrosion resistance, easy installation features, is widely used in water supply, drainage and other industries. And exported to over 30 countries and regions in the world. In the domestic and international market has a high visibility, reputation and market share. And passed ISO9001 quality system certification and ISO2531, ISO4179, ISO8179, EN545, EN598, BS6920 certification in kind. Liaocheng virtue Pipe Co., Ltd. ductile iron pipe is ideal for urban water supply pipes, gas pipeline network, high-set strength, ductility, and corrosion resistance and strong advantages, with the nature of iron, steel performance, is the traditional cast iron pipe and general Pipe replacement products; ductile iron pipe main components are carbon, silicon, manganese, sulfur, phosphorus and magnesium. On the ferrite and pearlite matrix distributed a certain number of spherical graphite ductile iron pipe, different caliber and to extend the requirement based on the nominal rate, the proportion of Fujian ductile iron pipe, the matrix structure of ferrite and pearlite are The difference, small-diameter ratio of pearlite generally not more than 20%, the general control of large diameter is about 25%. Minimum tensile strength: 420 / Mpa, minimum yield strength 300 / Mpa, a minimum elongation of 7%. Ductile iron pipe performance standards GB / T13295-2008 ISO2531 / 2008. Water-cooled metal mold centrifugal ductile iron pipe production technology and equipment 94 through the national scientific and technological achievements; ductile iron pipe was named the year 1994 state-level new products; ductile iron pipe in 2002 won the national quality metallurgical products Gold Award. Products undergo strict composition analysis, metallurgical testing, dimensional inspection, surface quality inspection, pressure ring test, tensile testing, hardness testing, hydrostatic testing, leak test, the thickness of the lining and the outer coating, such as quality inspection. All of the above test items qualified rear allowed the factory.
