Pig iron product won the national "Silver" award and the "National Building Material Co., Ltd. mainly produces Liaocheng Shunxiang ductile iron pipe, the specification is DN80-DN1600, users meet," the title; ductile iron pipe products in 1999 in Shandong Province Famous Brand lose Oil ductile iron pipe, in 2000 was named the National Metallurgical Product Quality Gold Award, and the National Bureau of Technical Supervision of the same industry user survey, won the title of Ductile brand in the industry. Ductile iron pipe not only for urban gas distribution and gas pressure underground pipe network, but also widely used in water, oil pipelines as well as food, pharmaceutical, chemical industry production process pipe network. My company produces ductile iron pipe can withstand high internal pressure during pressure testing, the experimental pressure than the international scale and European scales are higher than 1MPa. Ductile pipe also has good resistance to external pressure, can reduce the pipe bed and a protective layer making the request, the pipe laying economical and reliable; addition, zinc spray, spray paint asphalt, lined with cement and other measures to ensure the Ductile Iron Pipes inner and outer corrosion resistance. Zinc spray quality in line with ISO8179 Golden Ocean's delineation, per square meter of the pipeline a minimum amount of zinc spray 130g, not less than the thickness of asphalt paint 70μm, cement mortar lining quality conforms to ISO4179 delineated to ensure mortar rugged chamber, Smooth, strong adhesion. The company will always adhere to innovation, pragmatism, integrity and development of the business, sincerely welcome customers to negotiate and cooperate with you hand in hand to create a better future.
