Introduction PPVC Well Casing Pipe and Screen Pipes are an ideal prodcut for protection of domestic, irrigation, industrial & mining bore wells, keeping out the gravel pack and foreign particals providing clean and clear water from the bore wells. Water shortage is a global problem. Due to the serious corrosion problems of iron pipes and steel pipes, not only the service life of water wells is affected, but also many adverse consequences are produced, such as sand gushing, land subsidence, water pollution, ground subsidence, etc., which cause great losses every year. PVC pipe has the characteristics of light weight, strong corrosion resistance, good durability and low cost, so it is widely used in well engineering. PVC-U well pipe system is a new type of plastic pipe product developedaccording to the characteristics of PVC-U series water supply pipeline and market needs in the process of decades of production practice. The PVC-U water plumbing system is composed of PVC-U well wall pipe and PVC-U filter pipe, which is connected by strong thread. Specification
