About Bridge spanning pipe AIPOLY guard

This pipe is high- density polyethylene pipe with insulation for preventing pipes from freezing in cold areas.


  • Insulation

    By wrapping hard foaming polyurethane with heat insulation on the high-density polyethylene, freezing of liquid in the pipe can be prevented.

  • Weather resistance

    By adding carbon black, deterioration of pipes due to ultraviolet rays is suppressed and outside open piping enabled.

  • Airtight

    The welding part between pipes and fittings is integrated due to EF welding (electric fusion)/butt welding and thus, high airtight can be kept.

  • Easy construction

    It is lighter than metal pipes and thus it is easy to handle.
    Long pipes are supplied depending on its size, which leads to the easy-construction.

  • Quake resistance

    Polyethylene pipe has a high flexibility and thus can not be cracked by earthquake.
