DN100 ductile iron pipe

You know DN100 ductile iron pipe in which the design requirements? Jinrui www.dabaoji114.cn management company is specialized in producing water supply and drainage, manufacturers of gas pipe fittings. Let our company to explain to you: ductile iron pipe burial depth should be determined according to the freezing level, external load and other factors such as pipelines cross. Under normal circumstances, buried at the depth of 0.2 m below the frost line, and meet the following conditions: when the diameter is greater than 100mm, the top tube minimum depth of 1.20 meters. DN100 ductile iron pipe trench bottom width is generally designed tube diameter plus 0.5 meters, and according to soil conditions, determine the slope excavation (i) ductile iron pipe and other pipes, like a uniform flow along the head loss for hf = λ / dv2 / 2g, the only difference "λ"; (hydraulic friction coefficient), the head loss can be calculated from the original cast iron pipe, ductile iron pipe as the loss of local resistance and other pipe, head loss for uniform flow. hf = λ / dv2 / 2g, the only difference "λ"; (hydraulic friction coefficient), the head loss can be calculated from the original cast iron pipe local resistance. The emergence of ductile iron pipe for water utilities provides an excellent new pipe. In order to better application of ductile iron pipe in engineering, design and construction should be familiar with Qingdao ductile iron pipe and ductile iron pipe fittings, characteristic of ductile iron socket tee, continue to find problems and resolve them, to make more rational design, construction more standardized, so that the new pipe to play a greater role in water supply engineering.
