PVC-U drainage pipes with PVC resin as the main raw material, adding an appropriate amount of additives, the extrusion and injection molding of plastic products, mainly for the construction of drainage, rain water system. PVC-U drainage pipe has the following characteristics: 1, excellent physical and chemical properties. Production of PVC pipes and fittings, corrosion resistance, high impact strength, fluid resistance (30% compared with the same caliber of cast iron pipe flow), anti-aging, long service life (according to the Ministry of Construction show that the test data, the age of indoor 50 years 315 drains, outdoor 30 years) drains, is building drainage, Rainwater, an ideal material for chemical sewage. 2, light and practical, easy to install. Weighs only 1/5 of the same caliber of cast iron pipe, can greatly accelerate the progress of the project and reduce construction costs. 3, the wall is smooth, fluid drainage, pipeline clogging, check the mouth unique design. Facilitate inspection operation, without any tools. 4, saving construction costs. Use PVC-U Plastic Drain overall cost than using the same specifications as the cast iron pipe is low, lower maintenance costs. 5, the product in white, bright color, bright and smooth, can make a more modern building modern charm. Drain is formed by adding the high-density polyethylene (HDPE) and other additives exterior corrugated plastic pipe new seepage drainage, flooding the bellows is perforated by at recess, tube surrounded by outsourcing geotextile processing. According to the bellows can be divided into single-wall and double-wall bellows permeable permeable bellows. As the product of the hole in the trough and is elongated, effectively overcome the flat products susceptible to plugging the hole and the drawbacks affecting drainage effect for different drainage requirements drains Atlas, pore size can be 10mm × 1mm-30mm × 3mm, and can be 360 ??degrees, evenly distributed within the range of 270 degrees, 180 degrees, 90 degrees, widely used in highway, railway roadbed, the subway project, waste landfill, tunnels, green belts, playgrounds and slope protection, drainage areas due to the high water content of concrete drain specifications, as well as agriculture, horticulture of 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. Municipal sewer drain pressure depends on the size of the network, the choice of arms and straight wall tube bellows. Straight wall pipe pressure bearing ability, can be used for large-scale drainage outfall pipes dedicated network. 315 drains, drains, two-out plastic provided by Xiong Zan Pair bright plastic products factory. Xiong Zan Pair Ming plastics factory (1620231.707070.cn) strong, credible, in Baoding UPVC pipe industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead two-out plastic into the brilliant and you work for a better future!
