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 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, ductile iron pipes transporting drinking water Liaocheng price, pipes shall not pass through poison contaminated areas, should take precautions if they must pass through. 5, where the socket connection ductile iron pipes, ductile iron pipe 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, 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 pipes, fittings, ductile iron pipe wall thickness, 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. Ductile iron pipe and tube, also known as ductile iron pipe, ductile iron pipe is made of. Their different manufacturing methods can be divided into: sand centrifuge tube socket straight, continuous cast iron pipe straight pipe and sand. By its use of different materials can be divided into: gray iron, ductile iron and high silicon iron pipe. Cast iron pipes used for water supply, drainage and gas and other pipeline projects. Ductile iron pipe fittings used in connection trench technology, also known as clamp connection technology, has become the most important technology currently liquid, gas pipe connections, although the technology development in the country later than other countries, but because of its advanced technology nature, the domestic market will soon be received. From 1998 up to now developed k9 ductile iron pipe wholesale, through the development and application of a few years, has gradually replaced the two traditional pipe connection flanges and welding. Not only technically more mature markets generally recognized, and has been actively guide the national regulations and policies.
