Ductile Iron Pipe

Shandong Liaocheng Gerui Pipe Industry Co., Ltd. is a well-known joint-stock enterprise in China, specializing in the production and sales of ductile iron pipes and related accessories, as well as providing water supply and drainage and fire engineering services. Our company has two ductile iron pipe and pipe fittings production plants, with high degree of automation and mechanization of process equipment. If electric furnace, spectrum analyzer, etc The key equipment is imported from abroad. The whole production line of centrifugal forming, annealing, zinc spraying, finishing and packaging is at the leading level in China. The double short process continuous casting process of blast furnace electric furnace is adopted to produce centrifugal ductile iron pipes and pipe fittings in strict accordance with iso2531-2008 / 2009, GB / t13295-2013, en545, en598 and other standards. The main products are dn80-2000mm ductile iron pipes Products are widely used in gas transmission, water supply and other projects. Centrifugal nodular cast iron pipe is an ideal pipe material for urban water supply and gas pipeline network. It has the advantages of high strength, good plasticity and strong corrosion resistance. It has the nature of iron and the performance of steel. It is the replacement product of traditional cast iron pipe and ordinary steel pipe; The company has two centrifugal nodular cast iron pipe production plants, casting pipe product specifications from dn80-2600 mm, there are T-type, K-type, n-type, S-type and other interface forms; The production process and equipment of water-cooled metal centrifugal ductile iron pipe passed the national scientific and technological achievement appraisal in 1994; the ductile iron pipe was rated as a national new product in 1994; the process and equipment of DN 1200-1600mm centrifugal ductile iron pipe passed the identification of new products and new technical achievements organized by the State Machinery Bureau; and- The 2600 mm extra large diameter centrifugal nodular cast iron pipe project is listed as the national science and technology industry demonstration project; the epoxy ceramic lined ductile iron pipe has passed the evaluation of scientific and technological achievements organized by the Ministry of construction, and its technical indicators meet the inspection standards of the United States and are exported in batches, filling the domestic blank; S type and N1 type centrifugal nodular cast iron pipe for gas with flexible mechanical interface has been appraised as a national new product by the scientific and technological achievements appraisal organized by the Ministry of construction. The centrifugal ductile iron pipe is recommended by China urban water supply association and China Urban Gas Association. Centrifugal nodular cast iron pipe won the gold cup award of national metallurgical product quality in 2002.
