Abstract: A flexible hose assembly includes a flexible fluid permeable annular carcass arrangement having an inner and an outer diameter formed about a central axis. The carcass arrangement provides skeletal strength to the hose assembly against radial forces. The carcass arrangement has a plurality of interconnecting strips forming convoluted joints between the strips. The convoluted joints have an inner lip and an outer lip at opposite ends of the strips; and the carcass further comprises a plurality of channels formed along an entire length of first and second sides of the strips, the channels creating at least one fluid passage in each of the convoluted joint forming the carcass for the passage of fluids between the inner and outer diameters.

Abstract: A flexible hose liner is provided having a cylindrical body extending along a longitudinal axis from a first end to a second end. First and second sleeves form the cylindrical body by separate continuous ribbons having a plurality of convolutions formed in a helical pattern along the cylindrical body from the first end to the second end. A ring is formed in each revolution about the longitudinal axis of the continuous ribbon of the first and second sleeves. A plurality of rings form the cylindrical body, each ring has a first convolution and an ending convolution such that a mechanical connection is formed between the ending convolution of a preceding ring and the first convolution of a succeeding ring. The mechanical connection of the between the rings of the first sleeve being different from the mechanical connection of the rings of the second sleeve.
