Abstract:

To provide a multiple set pipe device having a cylindrical or regular polygonal piping showing constant longitudinal section or constant cross section in a longitudinal direction and having internal cavities demarcated by separation membranes.

In this multiple set pipe device in the case of a heptagonal device, six cavities are of irregular trapezoidal shape, and the remaining cavity is circular and arranged concentrically with an outer cylindrical piping 1. Each smaller side part 4 of each trapezoidal cavity and an inside outline 5 of the center cavity are outlined. The outer cylindrical piping 1 has seven cavities 2 demarcated by separation membranes 3 and has a constant longitudinal section profile, and the membranes 3 separate the trapezoidal cavities from the center cavity. The outer cylindrical piping 1 and the separation membranes 3 are made of high density polyethylene(HDPE).
