Pipe Liner - trenchless pipe rehabilitation

Material for pipe repair (pipe liners) – Products by TENOWO for use in trenchless pipe rehabilitation form the basis for various tube liners available on the market. Precision-tailored to our customers’ needs, our nonwovens are the base material for the application of special coatings and resin systems and are used particularly in curved pipes with varying diameters. With their single- or multilayer constructions of needle and/or stitch-bonded nonwovens, these so-called ‘flex-liners’ offer outstanding properties that meet the requirements for cured-in-place pipe (CIPP) applications. Our products are available in the weight range of 200 g/m² - 1300 g/m² and can be used in diameters from ND30 to ND300.
