communicating pipeline PVC pipe extruder productio

◆ feature and application It is mainly used to produce PVC high strength communicating perforated pipe. It has reasonable body, easy to operate, high degree of automatization, stable and reliable when it successively produces, can rapidly produce. The main material of PVC high strength communicating perforated pipe is high density PVC. Three plastic extruders together extrude molded pipes, which are mainly used as cover of cable and optical cable in freeway network communication project. Features of communicating pipeline: 1. stress resistance and aging resistance. Using high-quality improved PVC project plastic extrudes once, with high strength of shaping molding, the inner grid shape forms physics Steel structure, its rigidity is 10-100 times higher than common plastic pipe. It is not necessary to envelop, can replace steel tube put through the road safely. Smolder (namely the ability of quenching is good), anti corrosion, aging resistance, with the longevity of over 50 years. Comparation of stress resistance strength of some commonly used underground communicating pipeline: sort Double-wall corrugated pipe PE smooth-wall pipe Single-hole grid pipe stress resistance strength（Kn/m2） 9.2 10.2 144 stress resistance strength percentage 100% 111% 1565% Remark: data in the table are from the testing report of National Chemical building materials quality supervision and inspection center.
