Cored Double-Wall Polyethylene Pipe (Carrytube)<\/h1>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The cored double-wall polyethylene pipe is one of the most important products in the field of water and wastewater infrastructure, urban wastewater collection networks, drainage systems, and heavy civil construction projects. Due to its special, engineered design, this pipe has become a very suitable replacement for concrete, metal, and PVC pipes in many projects.<\/p>\n

The structure of this pipe consists of two layers:<\/p>\n

    \n
  • A corrugated outer layer (cored) to withstand external pressures<\/li>\n
  • A smooth inner layer for the smooth transmission of fluids<\/li>\n<\/ul>\n

    This combination gives the cored double-wall polyethylene pipe both high mechanical strength and fluid flow with minimal pressure loss.<\/p>\n

    Payesh Gostar Behin Andish Co. is a specialized supplier of various types of cored double-wall polyethylene pipe for civil construction, industrial, and urban projects throughout the country.<\/p>\n\n

    Structure of the Cored Double-Wall Polyethylene Pipe<\/h2>\n\n

    Outer Layer (Cored)<\/h3>\n

    The outer layer is designed in a corrugated shape so that it can withstand the pressures caused by:<\/p>\n

      \n
    • Soil<\/li>\n
    • Traffic load<\/li>\n
    • Ground settlement<\/li>\n
    • Dynamic loads<\/li>\n<\/ul>\n

      This design increases the ring stiffness of the pipe.<\/p>\n\n

      Inner Layer (Smooth)<\/h3>\n

      The inner surface is completely smooth and uniform, which ensures that:<\/p>\n

        \n
      • The wastewater flow moves without pressure loss<\/li>\n
      • Sedimentation is reduced<\/li>\n
      • Clogging along the pipe route is minimized<\/li>\n<\/ul>\n\n\"\"\n\n

        Technical Features of the Cored Double-Wall Polyethylene Pipe<\/h2>\n\n

        High Ring Stiffness<\/h3>\n

        These pipes have very high resistance against external pressures and are suitable for burial at various depths.<\/p>\n\n

        Suitable Hydraulic Performance<\/h3>\n

        The smooth inner surface increases the flow velocity and reduces friction.<\/p>\n\n

        Chemical Resistance<\/h3>\n

        It is completely resistant to acidic and alkaline materials, industrial wastewater, and corrosive environments.<\/p>\n\n

        Long Lifespan<\/h3>\n

        If executed correctly, these pipes can have a useful life of more than several decades.<\/p>\n\n

        Light Weight<\/h3>\n

        Compared to concrete and metal pipes, it is much lighter and has easier transport and installation.<\/p>\n\n

        Suitable Flexibility<\/h3>\n

        It has very good performance against ground settlement and environmental vibrations.<\/p>\n\n

        Complete Sealing<\/h3>\n

        Standard fittings prevent wastewater leakage and the entry of external water into the network.<\/p>\n\n
