Hefei ductile iron pipe, flexible cast iron pipes, ductile pipe Shunxiang provided by Shunxiang ductile pipe. Liaocheng Shunxiang Building Materials Co., Ltd. (www.lcsxjc.com) Shandong Liaocheng Premium Business League certification company, has Shunxiang other brands, has a good reputation, honesty, service-oriented "business alliance Service" icon on the page We will be happy to serve you! Liaocheng Shunxiang Building Materials Co., Ltd. is the most powerful ductile iron pipe manufacturer Jigang ductile iron pipe plant, perennial supply of ductile iron pipe, cast iron pipe fittings, flexible cast iron drainage pipes. Today we ask Liaocheng Shunxiang Building Materials Co., as we explain the whole process of ductile iron pipe installation. 1, the groove bottom width of the trench should be excavated the following equation: B = D1 +2 (b1 + b2) of the formula: B-outer edge of the excavation width of the groove bottom of the pipe (mm) D1-width of the pipe structure Working width (mm) b1-pipe side (mm) b2-pipe side support width (mm). 2, designed in accordance with the factors supporting the trench trench soil, groundwater, slotted section, loading conditions, require solid and reliable, to prevent landslides, shall not prejudice the support tube and pipe steady. 3, T-type interface in a vertical or horizontal pipe bend should be located buttress. Buttress size should be determined based on the calculated diameter, angle, work pressure and other factors. 4, when the delivery of drinking water pipes shall not pass through poison contaminated areas, should take precautions if they must pass through. 5, where the socket connection ductile cast iron pipes flexible pipelines must be calculated set Buttress, see National Building Standard Design Atlas 03SS505 "flexible water pipe interfaces buttress." 6, the outer ductile iron pipe anti-corrosion coating deposited tube should be based on soil conditions to select galvanized and epoxy asphalt coating or coatings higher requirements. 7, after the completion of the pipeline installation, pressure test, to use low chloride water flushing and disinfection of 0.03% aqueous solution of potassium permanganate. I believe that through the above explanation, we have a certain understanding of the installation of ductile iron pipe. Liaocheng Shunxiang Building Materials Co., Ltd. is a production and sales of centrifugal ductile iron pipe, ductile iron pipe fittings pieces quotes, flexible interface cast iron pipes, fittings, specialized large enterprises. We will always adhere to innovation, pragmatism, integrity and development of the business of ductile iron pipe, sincerely welcome customers to negotiate and cooperate with you hand in hand to create a better future.
