Product Information

Outline

This product was developed as dedicated pipes for large-diameter rainwater drainage on expressways. It maintains the same high water-tightness as Toyo Drain Ring Pipe.

Characteristics

  • Improved, outstanding water-tightness
    Water-tightness has been improved in comparison with that of conventional sockets.
  • Improved connection strength
    A dedicated socket has been developed and the adhesiveness of the pipe-socket connection improved.
    Water-tightness of the connection is 0.05 Mpa.
  • Low roughness coefficient
    The low flow resistance of the smooth inner walls results in an extremely smooth water flow.
    (n=0.010)
  • High withstanding pressure
    The unique crest-and-trough structure offers high flattening resistance.
  • Corrosion-resistant material
    Polyethylene material is used to provide resistance to corrosion and attacks by a wide range of chemicals, including acids and alkalis.
  • Outstanding workability
    Because the pipes are light and have excellent flexibility, transportation and laying down are easy.
  • Excellent impact resistance
    The use of polyethylene provides superior impact resistance.
