Introduction 1.Plastic well pipe and water purifier pipe research and develop, and apply, can efficiency solute cast iron and steel well pipe erode distortion, destroy, flow sand problems. 2. corrosion resistance :PVC pipe has stable chemical properties, can resist most of the acid and alkali. 3. Long service life: the service life of PVC pipe at set temperature and pressure is at least 50 years. 4. Good environmental health performance :PVC pipe health performance fully comply with GB/T17219 standard and the relevant water standards of the Ministry of Health of the People's Republic of China. 5.PVC pipe has good grooving (drilling) rate, strong compressive capacity, large transverse flow, in many areas is the best choice to replace reinforced concrete grooving (drilling) pipe. 6. Simple installation :PVC grooving (drilling) pipe joints: rubber ring joints, cement joints, can also be used for crew and flange joints.In addition, PVC-M pipe density is low, light weight, low requirements for workers and construction equipment,construction cost is lower than concrete pipe, steel pipe. 7. Smooth inner wall, no scale, easy flow, no blockage, excellent drug-resistant bacteria, can effectively ensure the long time use of straight pipe. Specification
