Liaocheng Shunxiang Building Materials Co., Ltd. is the most powerful ductile iron pipe manufacturer, year-round 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 a solid and reliable new ductile iron pipe 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 iron pipe ductile iron pipe price of Saint-Gobain, the calculation must be set up by the pier, see the 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, installing piping, pressure test after passing the ductile iron pipe, low chloride water rinse 0.03% aqueous solution of potassium permanganate and disinfection is appropriate. 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 pipes, fittings, flexible interface cast iron pipes, fittings, specialized large enterprises. We 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. Liaocheng Shunxiang Building Materials Co. is a ductile cast iron is an alloy of iron, carbon and silicon. Ductile iron is spheroidal graphite form, the general size of 6-7 grade graphite ductile iron pipe plant in Jinan Iron and Steel, Ductile requirements on the quality control of the ball for the 1-3 grade level (ball rate ≥ 80%) therefore the mechanical properties of the material itself have been better improvement, have essentially of iron, steel properties. Annealed ductile iron pipe, the microstructure of ferrite and pearlite, good mechanical properties.
