Diameter scope: (id) |¦ì50mm-|¦ì200mm Double wall corrugated pipe introduction Double wall corrugated pipe (id|¦ì50mm-|¦ì200mm) is a new type of plastic pipe. It has many advantages, such as high ring stiffness, high strength, light weight, noise damping, high uv stability, long life, good bend, high pressure, high impact strength, strong corrosion resistance, and cold and heat resistance and so on. It can be put sealed rubber ring in the troughs of the pipe¡¡¥s two sides. It has a very good waterproof seal. Double wall corrugated pipe can be laid in poorer sections of the geological and used for faster construction. Double wall corrugated pipe also can be widely used in communications, telecommunications, and cable lying. Double wall corrugated pipe line features: In order to meet the demand of plastic pipe market, huasu company designed and developed this hdpe double wall corrugated pipe extrusion line sbg 200 by absorbing advanced technology from foreign countries plastic machinery industry. This corrugated pipe extrusion line is the latest study achievement in the plastic extrusion field. This extrusion line is suitable for the high speed extrusion of hdpe, ldpe, and pp material. Sbg 200 hdpe double wall corrugated pipe extrusion line adopts directly extruding (single extruder or two extruders¡¡¥ co-extrusion) and formi
