Flexible ductile iron pipes, ductile iron pipes flexible prices, Shunxiang ductile pipe 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! The main component of ductile iron pipe with carbon, silicon, manganese, sulfur, phosphorus and magnesium. Standard GB/T13295-2003 ISO2531/2003 ductile iron pipe defined using the 18th over after adding casting molten iron ball agent, after the high-speed centrifugal casting machine centrifugal ductile iron pipe into a flexible ductile iron pipes manufacturer, said ductile iron pipe ([span] Ductile Cast Iron Pipes), referred to as the tube, ductile iron pipe and ductile iron pipe. Building Materials Co., Ltd. Liaocheng Shunxiang after using the 18th over ductile iron pipe casting molten iron was added nodulizer, after the high-speed centrifugal casting ductile iron machine into the pipe, called "ductile iron pipe" (Ductile Cast Iron Pipes) , referred to as the tube, ductile iron pipe and ductile iron pipe. 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 flexible ductile iron pipes specifications 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 pipelines, must be located buttress calculated, 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, piping installed, after the pressure test ductile iron pipes flexible prices, 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 pipe, ductile iron pipe fittings flexible pipes, 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.
