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. Since its establishment perfect DN300 ductile iron pipe, 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 ISO9001: 2000 quality Management System Certification. Professional ductile iron pipe factory sales units. Our company ductile pipe standards are in line with ISO2531-98E Company to maintain annual cash more than 10,000 tons. Specifications DN100-DN1200 ductile pipe GB full. Use of blast furnace production of phosphorus. Sulfur in quality cast iron ductile iron pipe by advanced centrifugal casting the current international annealing processes. Water-cooled metal mold centrifugal casting machine casting made. After annealing. socket trimmed. hydrostatic test. internal corrosion of reinforced steel frame. ductile steel prices interfaces in the form of T-Standard wall K9 grade level is .10 or higher level standard effective length of six meters. Ductile iron pipe advantage: the low-pressure pipe, ductile iron pipe with a safe and reliable operation, easy breakage rate, construction maintenance, excellent quick DN400 ductile iron pipe, corrosion resistance and other shortcomings ductile iron pipe: ductile iron pipe connection by human factors such as the operating level, a greater sense of responsibility and other factors, not as good as the advantages of PE pipe construction convenient .PE pipe: PE pipe has good corrosion resistance properties of the anti inorganic stronger than metal pipe, in burying corrosion when not needed, to facilitate construction. Small diameter PE pipe is superior to steel and ductile iron pipe on the price performance .PE tube was Disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have to have a certain effect on polyethylene. If the organic solvent to penetrate the polyethylene DN250 ductile iron pipe, there will be swelling of the physical properties on the decline, the pressure of poor performance resistant to temperature changes.
