Hengshui Xu Rui 1308 135 5830 You are welcome! Cast iron drain pipe bridge is mainly responsible for the bridge rain, highway drainage tasks. Cast iron drain pipe is formed by adding a high density of steel pipe material other auxiliary agents, for different drainage requirements, the pore size may be 10mm × 1mm-30mm × 3mm, and can be 360 ??degrees, 270 degrees, 180 degrees, evenly distributed within 90 degree angle range, widely used in highway, railway roadbed, the subway project, waste landfill, slope protection and other tunnels, green belts, playgrounds and high water content caused by drainage areas, as well as agriculture, horticulture The underground irrigation and drainage systems. It is the soft water pipe, plastic blind ditch has become China Civil Engineering Construction (seepage, drainage) in the three main products. Mainly used in railway bridges and drainage, highway guardrails on both sides of the bridge support and engineering and chemical sewage systems. The following works by the Hengshui Xu Rui Rubber Company for your brief iron bridge vent pipe properties and uses. First, the performance characteristics of two ways, the first is the drainage of security, one strength and pliable combine aspects. Orifice located trough, as a two-way effect peaks and filter fabric, orifice clogging, to ensure smooth drainage system; and a unique dual damascene structure effectively increases the external pressure strength of the product, the drainage system is not affected by outside pressure deformation draining effect. Second, the cast iron drain pipes are mainly used in the following areas: 1. highway vertical, horizontal drainage and flooding; 2. the back walls and ditches highway various vertical shift, horizontal drainage; 3. Tunnel underpass of drainage; The municipal engineering, water purification plants, sewage plants, landfills and other drainage; drainage 5 golf courses, sports fields, parks and other green spaces of Xiuxie; 6. Water Conservation hillside slope development; 7. site preparation works of the underground drainage ; at present, I plant vent pipe has been sent to Beijing, Tianjin, Shanghai, Chongqing, Mianyang, Zhuzhou, Hunan, Hubei, Guangxi, Shanxi Linfen, Ganzhou, Jiangxi, Shandong Yantai, Shenyang, Fujian Putian, Nanjing, Xuchang Taizhou, Zhejiang, Guizhou Zunyi, Shanxi Datong, Baotou, Inner Mongolia, Shaanxi Weinan, Tianshui, Gansu and other cities and regions.
