Inversion liner and liner components for conducts |
摘要 |
Inversion liners are provided which in a first embodiment include first and second flexible fabric layers joined to first and second glass fiber containing layers and joined in tubular form, whereby the first and second flexible fabric layers face one another. The second glass fiber containing layer further is bonded to a thin, third flexible fabric layer. A substantially fluid impermeable layer is applied to the opposite side of the thin, third flexible fabric layer. This method and liner construction can save one or more steps in the manufacture of glass-reinforced, polyester felt liners
