Scott & Fyfe have developed a new innovation in invertible seamless glass textile liners for the fast assistance of pipe rehabiliation systems


Alphaduct is an extremely flexible product range that offers a perfect solution for the repair of defective pipes with multiple bends of up to 90°. Virtually fold free, Alphaduct products are available in a range of diameters and thicknesses and provide a stable wall thickness even with a change of dimensions. Alphaduct has a 4-D construction and has been developed for use in complex laterals, drains and sewers. This textile has the capability to perform changes in diameter.  Our Alphaduct can be used in conjunction with a high temperature curing process and comes with the option of either a TPU or PVC coating.
